00:00:00.000 --> 00:00:00.880
SBU CFNS: Recording.

2
00:00:03.280 --> 00:00:03.860
Okay.

3
00:00:10.950 --> 00:00:11.600
Okay.

4
00:00:11.750 --> 00:00:12.609
SBU CFNS: All right.

5
00:00:13.440 --> 00:00:16.129
SBU CFNS: Okay, is everybody

6
00:00:16.360 --> 00:00:20.340
SBU CFNS: able to see my like the screen?

7
00:00:20.540 --> 00:00:25.349
SBU CFNS: Okay, what I did here is I took the drawing that we got from Chris.

8
00:00:25.400 --> 00:00:26.980
SBU CFNS: and I put

9
00:00:30.070 --> 00:00:33.790
SBU CFNS: right. What was, you know? Yeah, it's it's a

10
00:00:33.980 --> 00:00:35.580
SBU CFNS: so.

11
00:00:36.200 --> 00:00:42.339
SBU CFNS: Okay, I won't. Try to. I what I did is I on top of the jams. I laid out

12
00:00:42.430 --> 00:00:48.500
SBU CFNS: the 8 counters that we're presently, considering the building there are 38 wide

13
00:00:48.550 --> 00:00:53.090
SBU CFNS: in 150 long, and the redo is on the jan.

14
00:00:53.140 --> 00:00:58.499
SBU CFNS: So that's what I have in the middle that there's an 8 scintillators 15 by 3.8

15
00:00:59.070 --> 00:01:00.470
SBU CFNS: centimeter squared.

16
00:01:00.500 --> 00:01:01.999
SBU CFNS: and

17
00:01:02.450 --> 00:01:03.789
SBU CFNS: it was just to give

18
00:01:03.880 --> 00:01:05.710
SBU CFNS: our

19
00:01:06.220 --> 00:01:12.740
SBU CFNS: designer for figuring out the support where everything is going to go where they would be.

20
00:01:13.650 --> 00:01:27.460
SBU CFNS: And so here here's what I also gave them that. the rates for the electron are high right the up to 3.6 Megahertz and the positron rates are lower by factor of 10

21
00:01:29.980 --> 00:01:34.560
SBU CFNS: 130 kilohertz. And so what we

22
00:01:34.870 --> 00:01:39.159
SBU CFNS: want to do is to form a left right coincidence for each one of the

23
00:01:39.320 --> 00:01:55.239
SBU CFNS: scintillators and the simulators now have. We'll have 6 sims on that. We'll do a past some of of that, and then amplify them. Put it through a discriminator. so that's we. And then we'll do it, or of the electron arm to the

24
00:01:55.780 --> 00:02:02.800
SBU CFNS: that can form a fast coincidence. and then we will generate a trigger for the gems, and

25
00:02:02.930 --> 00:02:05.809
SBU CFNS: we want to be able to do

26
00:02:07.210 --> 00:02:13.609
SBU CFNS: coincidence, resolving time. I'm. I'm hoping it's somewhere better than 200 bicoseconds I don't.

27
00:02:13.800 --> 00:02:16.329
SBU CFNS: No, we we haven't yet reached that. However.

28
00:02:17.720 --> 00:02:18.500
SBU CFNS: So

29
00:02:18.730 --> 00:02:24.679
SBU CFNS: this is our first prototype bar. This is 30 Why, 150 long.

30
00:02:24.900 --> 00:02:29.909
SBU CFNS: and we had 4 sims on it, and we had. We use the scintillator that was

31
00:02:30.010 --> 00:02:32.659
SBU CFNS: in the shop 3 thick.

32
00:02:32.700 --> 00:02:47.609
SBU CFNS: there is a micron portal. It's an old one. It's not in very great shape, and this is what we got that? The timing from the end to end we call the top versus bottom. Here. The best we got was a sigma 525 P. P. Picoseconds.

33
00:02:47.810 --> 00:02:54.480
SBU CFNS: Okay, and I think that was done at 54 volts by its voltage. And we got 5, 34 at

34
00:02:54.540 --> 00:02:57.049
SBU CFNS: a slightly more operating conditions.

35
00:02:59.650 --> 00:03:01.850
SBU CFNS: Sorry

36
00:03:02.150 --> 00:03:05.560
SBU CFNS: this is you out the board?

37
00:03:13.110 --> 00:03:14.740
SBU CFNS: The real cost of fraction.

38
00:03:14.790 --> 00:03:15.920
SBU CFNS: Do you hear me?

39
00:03:15.960 --> 00:03:18.019
comparative on the board?

40
00:03:18.550 --> 00:03:21.390
SBU CFNS: We we did a direction for

41
00:03:22.790 --> 00:03:24.980
SBU CFNS: also amplitude

42
00:03:25.210 --> 00:03:31.230
SBU CFNS: And and so there's different ways of doing it. but but basically that was the best thing to get

43
00:03:31.480 --> 00:03:34.150
what? What's the Sorry, but what's the

44
00:03:36.440 --> 00:03:40.120
SBU CFNS: how? How wide are these in the expected line? Application

45
00:03:42.980 --> 00:03:45.740
SBU CFNS: It's almost 30 wide.

46
00:03:46.080 --> 00:03:48.950
SBU CFNS: Oh.

47
00:03:49.040 --> 00:03:51.560
SBU CFNS: that's what you're saying.

48
00:03:52.300 --> 00:03:53.550
SBU CFNS: Do you have a sense of?

49
00:03:55.630 --> 00:03:57.320
SBU CFNS: I can't do this now on my head right now.

50
00:03:57.970 --> 00:04:00.450
SBU CFNS: How long? What is the light propagation time?

51
00:04:00.690 --> 00:04:01.839
SBU CFNS: It's all right

52
00:04:02.840 --> 00:04:03.780
for it.

53
00:04:38.200 --> 00:04:45.820
SBU CFNS: I I believe those results were where we had across coincidence between the Alpha G Bar that that this is another

54
00:04:45.940 --> 00:04:57.119
SBU CFNS: there with his own electronics that that we were using. This one is 20 by 20 so it's it's a square bar that's 700 long.

55
00:04:57.160 --> 00:05:00.070
SBU CFNS: and then we cross that it? with our.

56
00:05:00.130 --> 00:05:01.819
SBU CFNS: So this is give or take

57
00:05:02.050 --> 00:05:10.600
SBU CFNS: the the time variation across the 2. And so you can see that this one is producing 500 people seconds as well.

58
00:05:12.170 --> 00:05:13.330
SBU CFNS: It's it's no better.

59
00:05:13.600 --> 00:05:15.299
SBU CFNS: And and then what we did

60
00:05:15.460 --> 00:05:23.979
SBU CFNS: we did the same thing they did. They took 2 of their bars and measured the time of flight of a cosmic ray going down through the top bar and the bottom bar

61
00:05:24.270 --> 00:05:31.159
SBU CFNS: right, and so we did the same thing. This is the time of light between the Alpha Bar and our test. For

62
00:05:31.270 --> 00:05:34.819
SBU CFNS: Okay. And here we got 335 people. Check.

63
00:05:36.900 --> 00:05:40.039
SBU CFNS: What's that from the

64
00:05:41.450 --> 00:05:46.389
SBU CFNS: this is for this is a coincidence single. And you guys are completely

65
00:05:46.630 --> 00:05:50.750
SBU CFNS: all the time

66
00:05:50.870 --> 00:05:56.940
SBU CFNS: at any time at the time of the day.

67
00:06:01.350 --> 00:06:10.159
SBU CFNS: Yeah.

68
00:06:11.480 --> 00:06:12.260
SBU CFNS: okay.

69
00:06:12.600 --> 00:06:13.380
SBU CFNS: And

70
00:06:13.580 --> 00:06:18.370
SBU CFNS: again we've tried to correct for the time lock for the very low pulsite signals.

71
00:06:19.250 --> 00:06:25.889
SBU CFNS: So this is the prototype that I was hoping to have new results. So we

72
00:06:30.250 --> 00:06:31.439
SBU CFNS: this is

73
00:06:31.660 --> 00:06:34.800
SBU CFNS: this is time over threshold. This one is

74
00:06:39.400 --> 00:06:46.259
SBU CFNS: they. They measured, they they stretch the signal, the amplified. They measured the they digitize the call site.

75
00:06:46.320 --> 00:06:51.699
SBU CFNS: I don't want to do any of that. We don't have time for for space, and just the

76
00:06:52.160 --> 00:06:56.070
SBU CFNS: so they? They're in a variable

77
00:06:57.600 --> 00:06:59.480
SBU CFNS: So this is what we did.

78
00:06:59.780 --> 00:07:03.930
SBU CFNS: We we now have the 4 or 4 scent. Later it arrived.

79
00:07:04.020 --> 00:07:06.460
SBU CFNS: so we made a new simulator.

80
00:07:07.070 --> 00:07:09.450
SBU CFNS: and this one is 38 wide.

81
00:07:09.780 --> 00:07:29.640
SBU CFNS: but we don't have an electronics board to read it out where the Sams are have to be sitting here, and eventually they'll be at 6.3 spacing for the new board. We're designing, so we wanted to put them onto the all board, and then we had to have a 7 and a half millimeters facing. So we built these

82
00:07:29.970 --> 00:07:35.359
SBU CFNS: asymmetric. My guys, okay, and unfortunately

83
00:07:35.530 --> 00:07:41.299
SBU CFNS: our technician who was going to mount this. He had them out more Sims on the board, because we already put.

84
00:07:41.370 --> 00:07:48.210
SBU CFNS: or if we only had 10 test Sims, we put 4 on one side and for the other, and we didn't have enough

85
00:07:48.240 --> 00:07:54.780
SBU CFNS: to have probably so. that's under way, and we'll have results on that

86
00:07:54.850 --> 00:07:57.449
SBU CFNS: probably before Christmas.

87
00:07:58.080 --> 00:07:59.730
SBU CFNS: So this is the

88
00:08:01.030 --> 00:08:05.860
SBU CFNS: what i'm proposing for the final design. So here we now have a 38 elevator

89
00:08:05.910 --> 00:08:07.610
SBU CFNS: counter with 6

90
00:08:08.190 --> 00:08:24.670
SBU CFNS: light guides with 6 point, 3 facing on each end. I I went to 6 because we're worried about damage, and we thought if they get a few of them get damaged, we could still continue running and not have to open up and exchange them. we'll also get more light with with 6 of them.

91
00:08:24.850 --> 00:08:25.560
So

92
00:08:25.680 --> 00:08:26.470
SBU CFNS: so we

93
00:08:27.250 --> 00:08:28.250
SBU CFNS: not, for

94
00:08:28.510 --> 00:08:29.760
SBU CFNS: this is the

95
00:08:30.510 --> 00:08:35.339
SBU CFNS: new electronics board that we've designed it Hasn't yet gone out for

96
00:08:35.830 --> 00:08:39.760
SBU CFNS: production. So now we have 12

97
00:08:40.450 --> 00:08:44.339
SBU CFNS: Sims mounted on one board. That will hold too simply

98
00:08:44.620 --> 00:08:48.509
SBU CFNS: right, 6 on each. The Alpha board has 16

99
00:08:48.570 --> 00:08:50.930
SBU CFNS: sims on one card, and

100
00:08:51.120 --> 00:08:55.679
SBU CFNS: so that would have had 4 4 times 4.

101
00:08:56.490 --> 00:08:57.420
SBU CFNS: So

102
00:08:58.030 --> 00:08:58.909
SBU CFNS: got it.

103
00:08:59.210 --> 00:09:01.349
SBU CFNS: What will happen here is we will

104
00:09:01.430 --> 00:09:09.340
SBU CFNS: do the sum of 6 on each end for the calendar. We send that through a pass amplifier, and then a discriminator.

105
00:09:09.480 --> 00:09:14.950
SBU CFNS: and we'll in the Fpga. We'll check for a father. Turn around

106
00:09:15.080 --> 00:09:26.429
SBU CFNS: versus the electron arm. Coincidence, and then the Fpga will read out both the leading edge of the trailing edge, so we can measure the title of the threshold and which is a crude measurement of the amplitude.

107
00:09:29.160 --> 00:09:36.600
SBU CFNS: So there's the other side of the board. Here these are polls for mountain

108
00:09:40.790 --> 00:09:48.919
SBU CFNS: the next stage is, we have to design a power Distribution Board. and we want to test false, so we can time everything in

109
00:09:49.150 --> 00:09:55.720
SBU CFNS: and account for any table length delays, and then we have to develop the Fpga trader system.

110
00:09:56.710 --> 00:09:57.640
SBU CFNS: And

111
00:09:57.970 --> 00:09:59.749
SBU CFNS: I put this in for y'all

112
00:09:59.920 --> 00:10:00.550
alright.

113
00:10:01.030 --> 00:10:03.840
SBU CFNS: Yeah.

114
00:10:04.060 --> 00:10:15.550
SBU CFNS: the detailed electron detailed electronics here. please ask me questions about it, which I couldn't answer. So there's about 4 slides here that I got

115
00:10:15.630 --> 00:10:26.140
SBU CFNS: about 2 weeks ago from our our electronics vehicle. So let's see. I'm trying to find yeah.

116
00:10:26.920 --> 00:10:30.639
SBU CFNS: hopefully, our which connect the the the Ips.

117
00:10:31.000 --> 00:10:32.859
SBU CFNS: Sorry. Each of the

118
00:10:33.090 --> 00:10:35.209
SBU CFNS: here's the read out. There's the 6.

119
00:10:35.390 --> 00:10:42.200
SBU CFNS: Number 6. Okay, there. oh, so so. So

120
00:10:43.780 --> 00:10:48.380
SBU CFNS: I would beat them out. I would put them in serious, because that makes them faster.

121
00:10:49.090 --> 00:10:49.900
I

122
00:10:51.980 --> 00:10:57.300
SBU CFNS: right? So so instead of I mean this essentially so sorry. Put them on serious.

123
00:10:57.740 --> 00:11:03.870
SBU CFNS: and and read out the current signal of all of them. You have to have their match lines into here.

124
00:11:04.000 --> 00:11:09.600
SBU CFNS: I mean that's that's the we

125
00:11:09.860 --> 00:11:11.890
SBU CFNS: bring them out in virtually all 6

126
00:11:12.150 --> 00:11:14.099
SBU CFNS: right. That's that's a power of us.

127
00:11:14.380 --> 00:11:18.949
SBU CFNS: but that. But the Ipm speed is essentially limited by its capacity.

128
00:11:19.260 --> 00:11:27.610
SBU CFNS: We have a capacitor on board to hold the the charge. No, no, no, basically the capacity of the ipm itself limits how fast the right time is.

129
00:11:28.160 --> 00:11:30.320
SBU CFNS: and if you put that in serious.

130
00:11:30.450 --> 00:11:32.770
SBU CFNS: the capacity is essentially

131
00:11:32.900 --> 00:11:34.690
SBU CFNS: divided by the number of

132
00:11:35.230 --> 00:11:39.700
SBU CFNS: side yet, so the capacity is lower, so the signal gets up faster.

133
00:11:40.330 --> 00:11:43.269
SBU CFNS: So you get probably better timing if you put them serious.

134
00:11:44.290 --> 00:11:47.759
SBU CFNS: Great! i'll talk to our designers like that.

135
00:11:49.780 --> 00:11:52.040
SBU CFNS: that's that's not how the other one was done.

136
00:11:53.930 --> 00:12:02.469
SBU CFNS: So in in news. We put the 2 of them in a series, and and I mean, we get a 100 people.

137
00:12:02.910 --> 00:12:05.030
SBU CFNS: Yeah, you also using construction.

138
00:12:05.250 --> 00:12:07.609
SBU CFNS: They use that in construction on it. Yes.

139
00:12:08.580 --> 00:12:10.949
SBU CFNS: but I don't think the walk

140
00:12:11.440 --> 00:12:13.539
SBU CFNS: it gets you from a 100 to 300.

141
00:12:19.480 --> 00:12:21.990
SBU CFNS: I'll. I'll talk to you about that.

142
00:12:22.160 --> 00:12:23.580
SBU CFNS: It's good for you.

143
00:12:25.050 --> 00:12:26.990
SBU CFNS: So here's Here's our cell now.

144
00:12:29.440 --> 00:12:30.950
SBU CFNS: And for now

145
00:12:31.200 --> 00:12:34.690
SBU CFNS: and the last one is, is

146
00:12:37.870 --> 00:12:43.689
SBU CFNS: any comments on this one? or maybe maybe you could send me your comments.

147
00:12:43.850 --> 00:12:47.259
SBU CFNS: Yeah, the one was the transistors.

148
00:12:48.270 --> 00:12:51.970
SBU CFNS: Maybe so. Yeah. So that's one side. Yeah.

149
00:12:52.890 --> 00:12:57.280
Okay.

150
00:12:58.100 --> 00:12:58.810
yeah.

151
00:13:03.150 --> 00:13:06.850
SBU CFNS: yeah. But it's the same as I. Yeah, okay.

152
00:13:07.400 --> 00:13:08.449
SBU CFNS: You take a look.

153
00:13:12.300 --> 00:13:15.050
SBU CFNS: Any other comments, questions

154
00:13:15.810 --> 00:13:24.730
Konstantin (Vancouver, BC): From Constant here Just one comment. This was designed for the Alpha G experiment at the Sur, and the B is over there 3 meter long.

155
00:13:24.860 --> 00:13:30.060
Konstantin (Vancouver, BC): so that that's probably why they didn't go for ultimate possible resolution from these senses.

156
00:13:33.390 --> 00:13:38.459
SBU CFNS: It was it time we decided. We just adjusted the volume of concentrate you all right.

157
00:13:39.260 --> 00:13:41.060
SBU CFNS: so we'll speak again.

158
00:13:41.100 --> 00:13:46.680
Konstantin (Vancouver, BC): This was designed for the Alpha G Experiment that the so it was 3 meter long Boris.

159
00:13:47.410 --> 00:13:49.380
Konstantin (Vancouver, BC): for doing time of light measurement.

160
00:13:49.400 --> 00:13:52.660
Konstantin (Vancouver, BC): So probably that's why they did the go for ultimate

161
00:13:52.690 --> 00:13:55.479
Konstantin (Vancouver, BC): resolution because it was not needed it.

162
00:13:57.180 --> 00:14:02.650
SBU CFNS: Yeah. But John is saying we could get a better rush time if we some of the

163
00:14:02.760 --> 00:14:04.710
SBU CFNS: and we devoted series.

164
00:14:05.460 --> 00:14:10.450
Konstantin (Vancouver, BC): Yeah, yeah, that's that's what i'm saying, I really need it. Probably didn't do it because it was not needed

165
00:14:10.700 --> 00:14:12.760
Konstantin (Vancouver, BC): for the Alpha Jeep design.

166
00:14:14.400 --> 00:14:17.229
SBU CFNS: Yeah, we'll have to talk to Peter, and there goes next to me.

167
00:14:20.560 --> 00:14:24.610
SBU CFNS: We have the layout, but you know 6 of them are serious.

168
00:14:25.090 --> 00:14:33.939
SBU CFNS: It would be 6 times the 60.

169
00:14:35.530 --> 00:14:37.740
SBU CFNS: But it is for my speed

170
00:14:38.040 --> 00:14:38.720
awesome.

171
00:14:39.650 --> 00:14:40.330
Yeah.

172
00:14:44.990 --> 00:14:47.469
SBU CFNS: I mean, 2 is, Find this class as well.

173
00:14:49.890 --> 00:14:53.070
SBU CFNS: The

174
00:14:54.120 --> 00:14:57.019
SBU CFNS: we have.

175
00:14:58.620 --> 00:15:01.350
SBU CFNS: we don't have individual thresholds for each.

176
00:15:01.770 --> 00:15:06.839
SBU CFNS: So what we have is an adjustment for the 6

177
00:15:10.040 --> 00:15:12.090
SBU CFNS: we have individual.

178
00:15:12.550 --> 00:15:15.140
SBU CFNS: you know we can get adjusted, maybe

179
00:15:15.750 --> 00:15:16.660
SBU CFNS: 6.

180
00:15:16.880 --> 00:15:19.579
SBU CFNS: The same

181
00:15:20.210 --> 00:15:20.990
right?

182
00:15:29.640 --> 00:15:31.949
SBU CFNS: It's nice.

183
00:15:32.960 --> 00:15:34.430
SBU CFNS: because normally they have

184
00:15:41.440 --> 00:15:42.760
Yeah.

185
00:15:43.030 --> 00:15:57.729
SBU CFNS: that well, we can just threshold 36, and what we got

186
00:15:57.980 --> 00:15:59.720
SBU CFNS: I remember very well.

187
00:16:00.210 --> 00:16:05.990
SBU CFNS: I haven't

188
00:16:06.030 --> 00:16:07.020
all that we are

189
00:16:16.510 --> 00:16:17.480
SBU CFNS: so

190
00:16:17.980 --> 00:16:22.819
SBU CFNS: so I don't know if you use a new for black, or even before

191
00:16:27.030 --> 00:16:28.979
SBU CFNS: I think, and he saw to them

192
00:16:29.430 --> 00:16:32.700
SBU CFNS: we saw the

193
00:16:33.750 --> 00:16:37.020
SBU CFNS: the.

194
00:16:37.120 --> 00:16:41.529
SBU CFNS: and so we started that to be similar.

195
00:16:41.730 --> 00:16:46.149
SBU CFNS: But we didn't actually have an individual setting any more. The whole world was power with one.

196
00:16:46.400 --> 00:16:55.110
SBU CFNS: This is actually confusable Reason I know this is because when we kind of find the documentation, how we set them per channel on those boards. The answer is, we get that

197
00:16:55.190 --> 00:17:08.470
SBU CFNS: they they were matched, but the the the tricky part is I. It's not. Let's say, 2 281 is out of 60 voice. It's 231 out of the

198
00:17:08.950 --> 00:17:11.770
SBU CFNS: so it does change your

199
00:17:11.829 --> 00:17:13.589
SBU CFNS: I,

200
00:17:21.920 --> 00:17:27.229
SBU CFNS: but that that's not one about having them daily check, because that you can be good combinations.

201
00:17:28.220 --> 00:17:30.529
SBU CFNS: We have a total

202
00:17:30.960 --> 00:17:42.050
SBU CFNS: right.

203
00:17:44.090 --> 00:17:46.140
SBU CFNS: hey? That's all I had.

204
00:17:47.620 --> 00:17:49.740
SBU CFNS: So

205
00:17:50.490 --> 00:17:58.720
SBU CFNS: any any questions. I I guess it kind of had a general question. we're we're going to be doing some tests

206
00:17:58.730 --> 00:18:10.729
SBU CFNS: data taking that at at some point next year. we'll use for you ready, and we don't for that, or we can attempt for not so we're not going to attempt to use the board. We have to have a lab. Okay.

207
00:18:10.950 --> 00:18:16.140
SBU CFNS: these I'm. Hoping that out the board might be in the

208
00:18:18.260 --> 00:18:22.649
SBU CFNS: We haven't, yet they the this

209
00:18:22.720 --> 00:18:27.580
SBU CFNS: next.

210
00:18:29.050 --> 00:18:34.070
SBU CFNS: and we will also, you know.

211
00:18:42.750 --> 00:18:45.360
SBU CFNS: we tested 2 different lengths of life. Got it?

212
00:18:56.330 --> 00:19:00.580
SBU CFNS: I think they

213
00:19:01.280 --> 00:19:02.490
SBU CFNS: right, because it's

214
00:19:02.720 --> 00:19:04.830
SBU CFNS: essentially what to take is to take.

215
00:19:04.880 --> 00:19:07.909
SBU CFNS: I just hopefully. At the same time I will take care of that.

216
00:19:08.490 --> 00:19:16.899
SBU CFNS: and and by the theorem it can go back to a smaller area, and it's the same line. It must be longer

217
00:19:16.920 --> 00:19:18.059
SBU CFNS: at a same moment.

218
00:19:18.220 --> 00:19:26.310
SBU CFNS: so so ideally, if if you get more

219
00:19:29.160 --> 00:19:31.290
so.

220
00:19:31.660 --> 00:19:34.359
SBU CFNS: we we we

221
00:19:39.800 --> 00:19:41.930
SBU CFNS: no, it's a trade off.

222
00:19:42.010 --> 00:19:46.360
SBU CFNS: I'm just looking up

223
00:19:55.270 --> 00:19:58.970
SBU CFNS: and and the

224
00:19:59.020 --> 00:20:03.120
SBU CFNS: it's optimized to.

225
00:20:13.690 --> 00:20:15.190
So, you know.

226
00:20:15.810 --> 00:20:19.740
SBU CFNS: Yeah.

227
00:20:19.940 --> 00:20:20.680
let me go.

228
00:20:31.900 --> 00:20:36.770
SBU CFNS: Okay.

229
00:20:37.550 --> 00:20:38.370
I don't even

230
00:20:39.420 --> 00:20:45.680
SBU CFNS: the

231
00:20:46.140 --> 00:20:49.980
SBU CFNS: No, i'm a little board that we can trade off collecting all of the night.

232
00:21:08.690 --> 00:21:09.480
Okay.

233
00:21:14.130 --> 00:21:18.039
SBU CFNS: So so one thing, I'm.

234
00:21:18.470 --> 00:21:21.480
SBU CFNS: There is also in the

235
00:21:25.600 --> 00:21:26.440
SBU CFNS: and

236
00:21:26.890 --> 00:21:33.150
SBU CFNS: I don't know how we are right, all of the all the same.

237
00:21:37.420 --> 00:21:40.290
SBU CFNS: everything the same

238
00:21:40.770 --> 00:21:43.410
SBU CFNS: on the

239
00:21:43.430 --> 00:21:46.070
SBU CFNS: to change the

240
00:21:47.240 --> 00:21:49.100
SBU CFNS: I have no idea

241
00:21:49.390 --> 00:21:56.389
SBU CFNS: how much time.

242
00:21:58.650 --> 00:21:59.670
SBU CFNS: So

243
00:21:59.870 --> 00:22:00.859
SBU CFNS: I mean this

244
00:22:01.160 --> 00:22:04.140
SBU CFNS: the month.

245
00:22:28.160 --> 00:22:30.110
SBU CFNS: That's small for you. Okay?

246
00:22:30.540 --> 00:22:33.220
SBU CFNS: Oh, well.

247
00:23:18.320 --> 00:23:20.360
SBU CFNS: I mean, yeah, I mean

248
00:23:49.100 --> 00:23:50.090
more like.

249
00:24:05.590 --> 00:24:06.330
yeah.

250
00:24:15.210 --> 00:24:20.009
SBU CFNS: how much?

251
00:24:48.460 --> 00:24:50.689
SBU CFNS: Only if we know how much.

252
00:25:18.360 --> 00:25:20.609
SBU CFNS: So this is a little bit.

253
00:25:28.500 --> 00:25:35.260
Yeah.

254
00:25:50.400 --> 00:25:51.060
go ahead.

255
00:25:54.800 --> 00:25:58.729
SBU CFNS: So let's say you can go back to June. 1020,

256
00:25:58.960 --> 00:26:02.320
SBU CFNS: So it's already. And then you go back to this.

257
00:26:09.820 --> 00:26:14.660
SBU CFNS: so

258
00:26:17.190 --> 00:26:26.359
SBU CFNS: Yeah, okay, pretty good. so we came up with, for we we're saying this for good time. Yeah.

259
00:26:26.590 --> 00:26:31.500
SBU CFNS: So I believe next is

260
00:26:31.880 --> 00:26:32.949
SBU CFNS: I got it.

261
00:26:38.460 --> 00:26:48.099
Konstantin (Vancouver, BC): I get you close because you close. I put the URL in the chat. If somebody wants a copy.

262
00:26:48.220 --> 00:26:49.360
SBU CFNS: sure.

263
00:26:50.290 --> 00:26:53.009
SBU CFNS: Oh, i'll, I'll run it here.

264
00:26:54.240 --> 00:27:03.150
SBU CFNS: I uploaded it. Yeah, if you can, if you can zoom out so you can see the whole thing. Yeah. Good. Good. Good. Yeah.

265
00:27:04.110 --> 00:27:05.190
Konstantin (Vancouver, BC): The

266
00:27:06.690 --> 00:27:09.570
Konstantin (Vancouver, BC): So you can see the beam is coming in

267
00:27:09.660 --> 00:27:13.560
Konstantin (Vancouver, BC): from the left, and bunches of 1.5, nanosecond

268
00:27:14.330 --> 00:27:18.719
Konstantin (Vancouver, BC): a heating the target. Then the electrons go one way, positron, go one way.

269
00:27:19.290 --> 00:27:25.789
Konstantin (Vancouver, BC): and it says their electron rate is a megahertz and positron rates is kilohertz.

270
00:27:26.490 --> 00:27:27.570
Konstantin (Vancouver, BC): Oh.

271
00:27:27.760 --> 00:27:32.560
Konstantin (Vancouver, BC): and I say, I I kind of believe this, but in this environment I really have.

272
00:27:33.170 --> 00:27:36.919
Konstantin (Vancouver, BC): It's hard to project how noisy it's going to be.

273
00:27:39.060 --> 00:27:45.810
Konstantin (Vancouver, BC): Then the signals from the discriminators on the board as might is just described to go into.

274
00:27:45.830 --> 00:27:47.200
Konstantin (Vancouver, BC): and the Fpga

275
00:27:47.320 --> 00:27:49.550
Konstantin (Vancouver, BC): and the cables are fairly.

276
00:27:50.710 --> 00:27:52.990
Konstantin (Vancouver, BC): I don't know how long these cables are going to be.

277
00:27:53.120 --> 00:27:56.070
Konstantin (Vancouver, BC): There could be a lot. These these are going to be echoed.

278
00:27:56.390 --> 00:27:57.700
Konstantin (Vancouver, BC): I report cables.

279
00:27:59.640 --> 00:28:09.589
Konstantin (Vancouver, BC): Then they arrive into the Fpga and you form an an or between the electron side and push it up, quiz it on side, and then you go into coincidence

280
00:28:11.340 --> 00:28:13.710
Konstantin (Vancouver, BC): and the queens. The coincidence

281
00:28:14.360 --> 00:28:20.770
Konstantin (Vancouver, BC): trigger is the geometry doubt, and the trigger is the Ttc. To measure the time and the

282
00:28:20.850 --> 00:28:23.880
Konstantin (Vancouver, BC): false legs, which is the PAL size

283
00:28:24.740 --> 00:28:34.880
Konstantin (Vancouver, BC): all of the hits. And then the whole thing goes into the Midas. I, PC. And my Us. Is our data acquisition system developed by Stefan Rit out of Psi

284
00:28:37.480 --> 00:28:41.599
Konstantin (Vancouver, BC): the 2. The the challenges in this

285
00:28:41.900 --> 00:28:44.570
Konstantin (Vancouver, BC): our project is the high rate

286
00:28:45.040 --> 00:28:56.500
Konstantin (Vancouver, BC): of a Megahertz is out of a counter, and that makes it difficult to use a commercial Tdc. Like Vbtdc. Is from Kay, and like an 1190, which we have it

287
00:28:56.540 --> 00:29:00.469
Konstantin (Vancouver, BC): big numbers which have good resolution for this experiment.

288
00:29:03.190 --> 00:29:05.430
Konstantin (Vancouver, BC): and it's hard to use

289
00:29:07.050 --> 00:29:09.849
Konstantin (Vancouver, BC): some like Trp. Cdc.

290
00:29:09.890 --> 00:29:17.110
Konstantin (Vancouver, BC): Which is, which is kind of would be the right thing. But it we cannot add this custom, coincidence, logic inside of it.

291
00:29:19.050 --> 00:29:21.470
Konstantin (Vancouver, BC): So rate is one challenge.

292
00:29:21.850 --> 00:29:23.410
Konstantin (Vancouver, BC): the timing

293
00:29:23.660 --> 00:29:28.580
Konstantin (Vancouver, BC): result. In this 1.5 nanosecond, the bunches is the other challenge.

294
00:29:29.710 --> 00:29:38.360
Konstantin (Vancouver, BC): and to time the coincidence we hope to use these 5 delays that are present in all of the Fpga inputs

295
00:29:41.510 --> 00:29:44.320
Konstantin (Vancouver, BC): and the 4 major tight coincidence.

296
00:29:44.450 --> 00:29:47.900
Konstantin (Vancouver, BC): It is going to be also difficult, and we hope

297
00:29:48.120 --> 00:29:49.970
Konstantin (Vancouver, BC): for the trigger

298
00:29:50.190 --> 00:29:52.639
Konstantin (Vancouver, BC): to be of the order of one kilohertz.

299
00:29:53.080 --> 00:30:00.690
Konstantin (Vancouver, BC): as I'm. Told the maximum GM. Firing rate is of the order of a 5 kilohertz, so we don't want to waste that time.

300
00:30:00.720 --> 00:30:03.430
Konstantin (Vancouver, BC): and hopefully, we'll be able to control that somehow

301
00:30:04.470 --> 00:30:08.769
Konstantin (Vancouver, BC): by increasing the coin. So it's or decreasing it.

302
00:30:11.030 --> 00:30:16.690
Konstantin (Vancouver, BC): The Tdc. We're going to implement a the Fpga Tdc. A wavelet. Tdc.

303
00:30:17.250 --> 00:30:23.480
Konstantin (Vancouver, BC): These I do not expect big difficulties. This has been done by others many times now.

304
00:30:25.130 --> 00:30:30.739
Konstantin (Vancouver, BC): and the big challenge is to measure the both the arrival, time and the pulse.

305
00:30:31.650 --> 00:30:33.320
Konstantin (Vancouver, BC): Ian. And if you should wait.

306
00:30:35.550 --> 00:30:43.559
Konstantin (Vancouver, BC): and that's why we were under to trouble with a commercial Tdc Trb. 3 where it had trouble measuring the pulse width.

307
00:30:45.040 --> 00:30:46.870
SBU CFNS: Surprise?

308
00:30:47.410 --> 00:30:56.169
SBU CFNS: Yeah, I mean, we have to be bad experiences. Dv: 3 to amuse. Yeah, yeah, but we're using it an Al Fuji experiment to measure the type of light

309
00:30:56.480 --> 00:30:59.179
Konstantin (Vancouver, BC): type of light of the

310
00:30:59.420 --> 00:31:03.860
Konstantin (Vancouver, BC): particles and the old indication that it works for that application quite Well.

311
00:31:05.000 --> 00:31:07.799
Konstantin (Vancouver, BC): we do see it crash twice a day.

312
00:31:08.080 --> 00:31:18.649
SBU CFNS: So so that's a that's pretty good stand out for.

313
00:31:20.780 --> 00:31:24.560
Konstantin (Vancouver, BC): So that's pretty much the shape of the shape of this system.

314
00:31:25.440 --> 00:31:32.439
Konstantin (Vancouver, BC): So there's going to be some about 3 Kfpga programming, which is kind of for me. That's the challenge the interested in this.

315
00:31:32.950 --> 00:31:34.180
SBU CFNS: So so

316
00:31:35.010 --> 00:31:38.849
SBU CFNS: I have a any question, what what does Cp mean?

317
00:31:39.440 --> 00:31:40.850
SBU CFNS: How does that happen?

318
00:31:40.880 --> 00:31:45.649
Konstantin (Vancouver, BC): So this is a signals from the accelerator that we usually use

319
00:31:45.800 --> 00:31:48.939
Konstantin (Vancouver, BC): in this kind of experiments. So we have the Rf. Signal.

320
00:31:49.230 --> 00:31:55.240
Konstantin (Vancouver, BC): which is the Rf. Clock of the accelerator, and the Cp. Is the capacity of probe.

321
00:31:55.640 --> 00:32:11.049
SBU CFNS: which is also a signal that actually sees over actual particles going through the accelerator. It's it's a non-intercepting tour line that goes through. So it's it's the proportional to the current. Yeah, okay, so we we can use this also a lot. The the

322
00:32:11.060 --> 00:32:15.769
SBU CFNS: the problem I have with with the being to the machine people is I. I want that past

323
00:32:16.060 --> 00:32:25.539
SBU CFNS: timing signal on that. I think they integrate it to a microsecond. You need to use this for us, so that' be issue. But we have about for our proton being.

324
00:32:25.600 --> 00:32:43.319
SBU CFNS: and in the the cyclotron for all of our baseline experiments we have it 2023 Megahertz, and we would get a fast signal. It could probably be fast control and feed it into our Tdc. To get the beam. The time to fight along the beam line. So so the the other problem I see is that i'm not sure.

325
00:32:43.510 --> 00:32:46.349
SBU CFNS: Weather like a like 7 times

326
00:32:46.510 --> 00:32:48.339
SBU CFNS: for, and logic

327
00:32:48.440 --> 00:32:50.590
SBU CFNS: can get us down

328
00:32:50.710 --> 00:32:54.500
SBU CFNS: in the in the window in the coincidence window.

329
00:32:54.540 --> 00:32:57.739
SBU CFNS: so that the that the coincidence rate is small enough.

330
00:32:58.200 --> 00:33:04.470
SBU CFNS: So so what what I had in mind was that we would actually base this on the Tdc results.

331
00:33:04.680 --> 00:33:09.479
SBU CFNS: So the the digital part of the Fpga it would look at the

332
00:33:09.740 --> 00:33:13.540
SBU CFNS: maybe you can correct the time for time of the threshold.

333
00:33:13.680 --> 00:33:14.849
SBU CFNS: and then make

334
00:33:15.050 --> 00:33:16.909
SBU CFNS: That's not a window

335
00:33:17.060 --> 00:33:21.359
SBU CFNS: on the corrective. Cdc. Times and trigger the javascript.

336
00:33:21.510 --> 00:33:25.070
SBU CFNS: Well, that's what I was thinking about, but it's not about in here, right?

337
00:33:26.330 --> 00:33:28.539
Konstantin (Vancouver, BC): That certainly is a possibility.

338
00:33:28.580 --> 00:33:32.459
SBU CFNS: It is a possibility. The

339
00:33:33.840 --> 00:33:35.240
Konstantin (Vancouver, BC): I

340
00:33:36.940 --> 00:33:39.820
Konstantin (Vancouver, BC): we we're thinking for off-site

341
00:33:40.040 --> 00:33:43.629
Konstantin (Vancouver, BC): to to be able to resolve the individual budget beams or slides.

342
00:33:44.500 --> 00:33:49.580
Konstantin (Vancouver, BC): Yeah, my mind, I think I don't think we'll be able to resolve it. You will be Budget pibs.

343
00:33:49.880 --> 00:33:52.650
Konstantin (Vancouver, BC): So for me a coin that it's fairly rough.

344
00:33:53.060 --> 00:34:00.719
Konstantin (Vancouver, BC): but gives us a useful gym trigger rate. I, after making it from the Tgc output.

345
00:34:00.780 --> 00:34:02.730
Konstantin (Vancouver, BC): could be a possibility.

346
00:34:03.700 --> 00:34:09.270
Konstantin (Vancouver, BC): But I do not give up on trying to make a tight coincidence.

347
00:34:09.370 --> 00:34:11.299
Konstantin (Vancouver, BC): using Fpga logic.

348
00:34:11.449 --> 00:34:14.059
Konstantin (Vancouver, BC): In the worst case I can feed the

349
00:34:14.239 --> 00:34:20.510
Konstantin (Vancouver, BC): posit positron and electron signals out and the build a little custom

350
00:34:20.790 --> 00:34:26.029
Konstantin (Vancouver, BC): one Nanosecond coincidence unit and feed the result back into the Fpga.

351
00:34:27.940 --> 00:34:36.390
SBU CFNS: If I cannot do this with using Fpga, I think, without the type of a threshold correction. Your your window cannot be so small.

352
00:34:37.290 --> 00:34:41.990
SBU CFNS: That's that's a problem. I can meet the type of a threshold information to make the window so small.

353
00:34:42.060 --> 00:34:44.959
SBU CFNS: because you have to correct the the signals

354
00:34:45.110 --> 00:34:46.390
SBU CFNS: on on a like

355
00:34:46.810 --> 00:34:49.679
SBU CFNS: event level by the time of thresholds.

356
00:34:50.870 --> 00:34:58.759
SBU CFNS: Yeah, so there's 2. There's 2 separate issues.

357
00:34:58.840 --> 00:35:07.219
SBU CFNS: Yeah, everything's better if you do that. That's that's what I thought he was going to do was actually trying to do the the

358
00:35:07.240 --> 00:35:17.469
SBU CFNS: yeah, but but it's the output of the Tdc. In the Fpga. Not just the

359
00:35:18.130 --> 00:35:18.790
SBU CFNS: like.

360
00:35:19.390 --> 00:35:21.829
SBU CFNS: First of all, logic all ends

361
00:35:24.250 --> 00:35:27.490
Konstantin (Vancouver, BC): the

362
00:35:27.660 --> 00:35:43.089
Konstantin (Vancouver, BC): they T. I I think the Ttc. Latency is going to be acceptable for this to trigger the gem. It's not going to come too late, so it's a possibility. But the question, the issue here is not time resolution. The issue is the GM. Trigger.

363
00:35:43.690 --> 00:35:44.439
SBU CFNS: Yeah.

364
00:35:46.180 --> 00:35:50.210
SBU CFNS: But but that's a function of the the coincidence. We know it's right.

365
00:35:50.370 --> 00:35:52.179
Konstantin (Vancouver, BC): That's correct. That's correct.

366
00:35:52.630 --> 00:35:59.230
Konstantin (Vancouver, BC): So if I control the coincidence of which in the box as end on my picture.

367
00:35:59.310 --> 00:36:05.800
Konstantin (Vancouver, BC): then we don't need to do it on the Tgc. If I can do it, then I will do it out of the Gcc. That's correct.

368
00:36:09.380 --> 00:36:10.930
Konstantin (Vancouver, BC): I think it should be doable.

369
00:36:11.690 --> 00:36:14.959
SBU CFNS: So so we can actually withstand quite a lot of

370
00:36:15.060 --> 00:36:23.720
SBU CFNS: latency because we have the Apv. We don't. We have 4 like 4 s. Yeah. 4 microseconds. So

371
00:36:24.600 --> 00:36:30.109
SBU CFNS: you can do actually, quite a lot of project in the Fpga kind of our blocks before the decision has to come out.

372
00:36:32.670 --> 00:36:36.529
Konstantin (Vancouver, BC): That's right. That's right. Yeah, this. This is a sufficient time.

373
00:36:38.390 --> 00:36:41.699
Konstantin (Vancouver, BC): Yeah, I I yeah, we'll think about this.

374
00:36:41.720 --> 00:36:43.569
Konstantin (Vancouver, BC): I think I think it's.

375
00:36:43.650 --> 00:36:47.310
Konstantin (Vancouver, BC): I think it's something something we can control much better

376
00:36:47.380 --> 00:36:48.589
Konstantin (Vancouver, BC): then the

377
00:36:48.750 --> 00:36:52.699
Konstantin (Vancouver, BC): but i'll try to do fast time in use of Fpga fabric.

378
00:36:53.220 --> 00:36:54.310
SBU CFNS: Yeah.

379
00:36:56.970 --> 00:37:03.150
SBU CFNS: that was our original request was to do the fast

380
00:37:04.500 --> 00:37:05.299
which.

381
00:37:06.970 --> 00:37:11.229
SBU CFNS: if it can be done, should should easily be available within my microphone.

382
00:37:11.970 --> 00:37:13.890
Konstantin (Vancouver, BC): Yeah, yeah, and

383
00:37:14.510 --> 00:37:21.260
Konstantin (Vancouver, BC): And then they came By their understanding of that we need to do this State coincidence.

384
00:37:21.450 --> 00:37:25.140
Konstantin (Vancouver, BC): and it's it's going to be challenged. It's going to be interesting.

385
00:37:27.190 --> 00:37:36.150
Konstantin (Vancouver, BC): They are F and the Cp. So I talk to some of the accelerator people, and it looks like all of these signals are too high frequency in this machine for us.

386
00:37:36.220 --> 00:37:38.340
Konstantin (Vancouver, BC): So that's that. Unfortunately.

387
00:37:38.440 --> 00:37:45.910
Konstantin (Vancouver, BC): it's not going to be this as useful as in the systems. We use another experiments here. No, but

388
00:37:46.400 --> 00:37:48.940
SBU CFNS: we could. What we used to do.

389
00:37:49.170 --> 00:37:50.100
Yes.

390
00:37:50.270 --> 00:37:53.379
SBU CFNS: we used to do a capacity probe, divide by 2,

391
00:37:53.780 --> 00:38:12.479
SBU CFNS: so we would use some past discriminators to get a logic call to short logic. I'll send it to a discriminator. Then use it out bar to detail the next one, so we would change the frequency from 23 megahertz to 44 megahertz, and and get a pulse every 88 nanoseconds instead of going to be 4.

392
00:38:12.540 --> 00:38:20.929
SBU CFNS: Yeah. So we know how to do that in external logic. Yeah, I don't. I mean you can just use a Pn. Which goes from 660 to 66.

393
00:38:21.440 --> 00:38:22.959
SBU CFNS: Right it will be.

394
00:38:23.480 --> 00:38:27.569
SBU CFNS: we would know. I mean, as long as that frequency is really stable.

395
00:38:28.350 --> 00:38:34.439
Konstantin (Vancouver, BC): Well, the 660 signal is a it's a microwave signal. It's not even an electrical signal.

396
00:38:35.640 --> 00:38:50.479
SBU CFNS: so it it's too high to to get into the Fpga, it would have to be externally locked up here as an external pl on it, and and and divide by 10, or divide by 8 or whatever to get it into something that the

397
00:38:50.520 --> 00:38:53.140
SBU CFNS: the Fpga can withstand.

398
00:38:53.330 --> 00:38:54.709
Konstantin (Vancouver, BC): Yeah, what?

399
00:38:55.030 --> 00:39:00.110
Konstantin (Vancouver, BC): And we're talking to the accelerator people to see what what signal they have that can do this for us.

400
00:39:00.290 --> 00:39:15.039
SBU CFNS: Yeah, we you don't track it down completely yet. We're going to have to do something about it with with the machine people for the and the electronics. But I I think we could solve with the rate problem into the Fpga. We can solve constantly, just by divided by 2 or 4. I mean.

401
00:39:15.220 --> 00:39:22.350
SBU CFNS: yeah, I think so. We want the time pick off. That's that's what we want to do on high resolution in that. Yeah.

402
00:39:22.460 --> 00:39:28.630
Konstantin (Vancouver, BC): yeah, if we can run it if you can run the synchronously with the beam. That would be very helpful.

403
00:39:29.340 --> 00:39:30.909
SBU CFNS: And I forgot about that.

404
00:39:33.270 --> 00:39:37.759
Konstantin (Vancouver, BC): Yeah. So that's that's about. I have any more questions

405
00:39:38.730 --> 00:39:40.659
SBU CFNS: that looks good. Thank you.

406
00:39:41.070 --> 00:39:52.149
Konstantin (Vancouver, BC): Oh, yeah, I forgot to mention. So for for development of all of this. we have our development, this station, which which is one Alpha bar and one. The dark light bar

407
00:39:52.220 --> 00:39:53.680
Konstantin (Vancouver, BC): was a for

408
00:39:54.620 --> 00:39:58.939
Konstantin (Vancouver, BC): 4 sets of electronics. So we have 4 Tdc signals

409
00:39:59.140 --> 00:40:04.900
Konstantin (Vancouver, BC): out of which we form. We can form the coincidence, and we can play with all of this using a cosmic race

410
00:40:05.220 --> 00:40:07.519
Konstantin (Vancouver, BC): and the source.

411
00:40:08.350 --> 00:40:11.969
SBU CFNS: Well, constantly. One thing came up this morning

412
00:40:12.040 --> 00:40:17.839
SBU CFNS: was the fact that right now we have 8 bars times 2, which is 16.

413
00:40:18.280 --> 00:40:21.799
SBU CFNS: and we read out both in. So there's 32 signals

414
00:40:21.920 --> 00:40:31.640
SBU CFNS: that we've got. And the question was, supposing we decided that we wanted 10 simulators instead of 8, which would increase the total number of signals up to 40.

415
00:40:31.660 --> 00:40:33.009
SBU CFNS: What can we do then?

416
00:40:33.410 --> 00:40:36.089
Konstantin (Vancouver, BC): Well, right now we're using a

417
00:40:36.110 --> 00:40:42.750
Konstantin (Vancouver, BC): use an Fpga port we built for the Alpha G experiment that happens to have the right number of connectors on it.

418
00:40:43.460 --> 00:40:48.049
Konstantin (Vancouver, BC): It is not clear that the Fpga on this board is a cyclone, 5,

419
00:40:48.120 --> 00:40:50.130
Konstantin (Vancouver, BC): not the fastest grade.

420
00:40:50.650 --> 00:40:58.699
Konstantin (Vancouver, BC): and we may want to use a faster Fpga, in which case we will build a different base board for it.

421
00:40:59.270 --> 00:41:04.440
Konstantin (Vancouver, BC): and it will have a different number of connectors, so we can put more connectors for more signals on it.

422
00:41:04.470 --> 00:41:11.080
SBU CFNS: so on that actually, I was in my

423
00:41:11.220 --> 00:41:22.020
SBU CFNS: expressed interest in working on a new version without the you know, chips because they don't exist anymore, plus having some external discriminators, and then some Fpga want.

424
00:41:22.210 --> 00:41:28.649
SBU CFNS: He probably would go with exciting sport. But if he built something new, I think he would be interested to cooperate with this.

425
00:41:28.960 --> 00:41:31.229
Konstantin (Vancouver, BC): So what is it? What is this

426
00:41:31.840 --> 00:41:32.799
SBU CFNS: minds.

427
00:41:32.820 --> 00:41:34.909
SBU CFNS: hey? One collaboration? How about that?

428
00:41:35.320 --> 00:41:37.620
SBU CFNS: Okay, okay, that's good. So

429
00:41:37.750 --> 00:41:47.779
SBU CFNS: yeah, let us know we can. We can have this kind of thing. But the worry we got was the software, and we went. When they delivered us with the board we looked soccer. It was all the Chinese

430
00:41:48.200 --> 00:42:06.320
SBU CFNS: software program. There was nothing about the the the way they were using the board in minds which that should be all in there. And so you know the Rd. Ap: People Weren't: really interested in. I think that's a communication problem. Yeah. But

431
00:42:06.330 --> 00:42:15.960
SBU CFNS: what we learned about this is we want someone on site who knows about the IP intimately when when it goes bad. So we don't have to buy you out or arrow

432
00:42:15.980 --> 00:42:19.179
SBU CFNS: it. Fix it right. So I think.

433
00:42:19.220 --> 00:42:19.930
okay.

434
00:42:20.230 --> 00:42:26.269
SBU CFNS: You know we can have a collaborative design. It's one thing but our ourda, you people have

435
00:42:27.720 --> 00:42:30.329
SBU CFNS: they. They have resources there which can help.

436
00:42:30.750 --> 00:42:34.089
SBU CFNS: but they can also build prototypes. They have to put their

437
00:42:34.130 --> 00:42:40.469
SBU CFNS: that which can just interest in building these folks. So you can get a return on time and all that stuff.

438
00:42:40.710 --> 00:42:56.809
SBU CFNS: Yeah, yeah, exactly, exactly, especially in the development of the Tgs of the Fpga, Tgc: and the calibration of that of the timing of it. Yup. So if you go with Sky, and he has libraries. He has written the Cdc. So you can just drop them in and and use them.

439
00:42:57.590 --> 00:42:58.419
Yup.

440
00:42:58.680 --> 00:42:59.580
Konstantin (Vancouver, BC): That's right.

441
00:43:02.020 --> 00:43:03.860
SBU CFNS: Okay, Thank you.

442
00:43:04.210 --> 00:43:05.370
Perfect, Captain.

443
00:43:05.640 --> 00:43:17.529
SBU CFNS: Okay, Thank you. I'm: okay. So you're right. I'm also interested in happy with this we we put you down. It's it's like the consult, and that's why here's the next talk.

444
00:43:17.710 --> 00:43:24.619
SBU CFNS: Okay, like there's 1 point, 2, 4.

445
00:43:26.170 --> 00:43:34.669
SBU CFNS: Oh, that means okay. So

446
00:43:34.720 --> 00:43:36.390
SBU CFNS: hmm. As well as everyone.

447
00:43:39.450 --> 00:43:46.209
SBU CFNS: And how much is, it

448
00:43:47.650 --> 00:43:52.489
SBU CFNS: that gives me a time difference.

449
00:43:53.110 --> 00:43:54.649
SBU CFNS: A little less.

450
00:43:55.000 --> 00:43:55.560
Yes.

451
00:43:57.190 --> 00:44:01.400
SBU CFNS: Well, it's 20 sending me this difference. So it's tropical. That

452
00:44:02.680 --> 00:44:05.670
SBU CFNS: 20 cm is two-thirds, of 1.2 meters

453
00:44:06.380 --> 00:44:07.729
SBU CFNS: for all.

454
00:44:07.970 --> 00:44:23.889
SBU CFNS: Well, Nanosecond, I I I have to contact via not to use this single speed in in cables every time, but it's actually fast.

455
00:44:23.990 --> 00:44:25.349
670,

456
00:44:30.330 --> 00:44:32.180
SBU CFNS: All right. Well.

457
00:44:33.350 --> 00:44:35.979
SBU CFNS: hey, next person, Michael, thank you.

458
00:44:37.320 --> 00:44:39.029
SBU CFNS: Where is your slides

459
00:44:43.590 --> 00:44:45.729
SBU CFNS: picture? He's on the

460
00:44:50.960 --> 00:45:09.270
SBU CFNS: but I don't have. I don't have drawings for this, but I i'm willing to show, Share a few photos here, and address a few

461
00:45:09.280 --> 00:45:12.290
SBU CFNS: of all talking points from previous meetings.

462
00:45:12.490 --> 00:45:14.760
SBU CFNS: So this photo here shows

463
00:45:15.100 --> 00:45:18.040
SBU CFNS: the gas outlets

464
00:45:18.140 --> 00:45:21.039
SBU CFNS: which all these fast couplers that are all

465
00:45:21.330 --> 00:45:24.959
SBU CFNS: attached, and and this this add some maybe

466
00:45:25.200 --> 00:45:30.270
SBU CFNS: half an inch or so

467
00:45:30.860 --> 00:45:41.710
SBU CFNS: that they come out. They stick out a little bit beyond the edge of the one they come out on the side. So in in the frame that's between the tool, the top and bottom of it. Yeah.

468
00:45:43.070 --> 00:45:44.229
And

469
00:45:47.830 --> 00:45:55.090
SBU CFNS: there's another shot that has now also more bolts attached on the side it these boats on the side.

470
00:45:55.230 --> 00:45:57.570
SBU CFNS: or actually to conceal

471
00:45:57.620 --> 00:46:06.140
SBU CFNS: the hold for the stretching schools that are place horizontal through the frame, and we have the inner frame.

472
00:46:07.370 --> 00:46:08.200
SBU CFNS: Okay.

473
00:46:08.230 --> 00:46:13.880
SBU CFNS: So so these have little over rings, and they, they are so rounded.

474
00:46:14.260 --> 00:46:15.600
SBU CFNS: the surrounding

475
00:46:15.820 --> 00:46:19.640
SBU CFNS: the in our chamber again, everywhere on the outside. So that adds

476
00:46:19.680 --> 00:46:21.190
SBU CFNS: a little bit of

477
00:46:22.630 --> 00:46:24.759
SBU CFNS: that's maybe the second need of

478
00:46:26.290 --> 00:46:26.930
Okay.

479
00:46:28.000 --> 00:46:28.870
SBU CFNS: All right.

480
00:46:29.200 --> 00:46:39.749
SBU CFNS: This this drawing, this drawing I did. then, when I was in, say bye, and and try to design something for the support of the electronics.

481
00:46:39.790 --> 00:46:41.760
SBU CFNS: We. So you see these

482
00:46:42.270 --> 00:46:46.130
SBU CFNS: 8 plus 4, so that that's 12 or 70 meters.

483
00:46:46.370 --> 00:46:52.720
SBU CFNS: and the width of this is here 52, and we you can get the same level head. So.

484
00:46:53.160 --> 00:46:59.060
SBU CFNS: But these are then attached as bench as as window benches, like I call them.

485
00:46:59.090 --> 00:47:06.020
SBU CFNS: to provide support for the for them cost that are plugged onto the Amazonic connectors

486
00:47:06.100 --> 00:47:08.169
SBU CFNS: that they are on the real port.

487
00:47:09.130 --> 00:47:14.260
SBU CFNS: And I play with some concepts of that. I mean, you see, some helping hands who

488
00:47:14.660 --> 00:47:22.429
SBU CFNS: with the installation of this. So you see some ap cards plugged on, and then i'm supported by these green.

489
00:47:25.660 --> 00:47:28.309
SBU CFNS: The

490
00:47:29.420 --> 00:47:31.250
SBU CFNS: that was pre-covered

491
00:47:32.190 --> 00:47:38.569
SBU CFNS: I was in the fall of 29 teams that I was no call with you. This is the standard Japanese way, and before the

492
00:47:39.230 --> 00:47:43.700
SBU CFNS: but I used to see them with the cover of the as well.

493
00:47:44.230 --> 00:48:01.410
SBU CFNS: So let me see you an approximate layer of we'll see how it's actually attached. If you see the the length here it's like 470 meters, and then it's 6 out, another 8 like for next 12 cm long. You have the HDMI connected on on the long side

494
00:48:01.540 --> 00:48:05.010
SBU CFNS: and the the voltage supply.

495
00:48:05.760 --> 00:48:09.610
SBU CFNS: I have a better shot of this. so with your

496
00:48:12.030 --> 00:48:17.319
SBU CFNS: and we figured out exactly how.

497
00:48:22.720 --> 00:48:29.739
SBU CFNS: Yeah. So so you see a a number of HDMI tables come out of here. They They are not so

498
00:48:30.160 --> 00:48:34.069
SBU CFNS: connected to anything else, but they would need to be.

499
00:48:34.820 --> 00:48:38.600
SBU CFNS: It's it's it's it to be tied to something.

500
00:48:39.820 --> 00:48:46.160
SBU CFNS: This is this is the long side here.

501
00:48:46.240 --> 00:48:47.060
SBU CFNS: and

502
00:48:47.140 --> 00:48:50.049
SBU CFNS: that is the

503
00:48:50.190 --> 00:48:55.119
SBU CFNS: These auxiliary elements can also be

504
00:48:55.140 --> 00:48:59.709
SBU CFNS: a different way. So I we we just place them here.

505
00:48:59.730 --> 00:49:02.559
SBU CFNS: These are on what's to go phone.

506
00:49:02.750 --> 00:49:05.030
SBU CFNS: but to duplicate the digital

507
00:49:05.090 --> 00:49:09.950
SBU CFNS: on Tedling, so one becomes 2, so 2 become 4

508
00:49:10.020 --> 00:49:13.339
SBU CFNS: that we to all be connected to the

509
00:49:13.690 --> 00:49:16.389
SBU CFNS: back planes, that there are 2 room.

510
00:49:16.450 --> 00:49:21.750
SBU CFNS: or at the back place on the long side. Well each. So 4 cards

511
00:49:21.770 --> 00:49:23.960
SBU CFNS: you like 4, 8 on the north side.

512
00:49:24.220 --> 00:49:30.830
SBU CFNS: and we have 8, 5,

513
00:49:31.660 --> 00:49:32.339
yeah

514
00:49:34.780 --> 00:49:39.549
SBU CFNS: which.

515
00:49:39.590 --> 00:49:43.490
SBU CFNS: And

516
00:49:44.040 --> 00:49:47.969
SBU CFNS: this proper coating or or cladding now

517
00:49:48.040 --> 00:49:48.729
us.

518
00:49:48.930 --> 00:49:52.639
SBU CFNS: I wanted to get an estimate, like if the cables

519
00:49:53.200 --> 00:49:55.919
SBU CFNS: we're back at the end of the by.

520
00:49:56.310 --> 00:49:57.040
SBU CFNS: Yeah.

521
00:49:58.400 --> 00:49:59.270
SBU CFNS: how much?

522
00:49:59.490 --> 00:50:09.509
SBU CFNS: What's that from this edge to how far you bet on the cable. That's probably adding another 8, 7, 7 min.

523
00:50:09.810 --> 00:50:11.580
8 to 17 years

524
00:50:12.200 --> 00:50:14.710
SBU CFNS: already at this

525
00:50:14.990 --> 00:50:18.150
SBU CFNS: 8 and 4, so it's 20 cm.

526
00:50:21.020 --> 00:50:21.689
SBU CFNS: hey?

527
00:50:21.730 --> 00:50:27.099
SBU CFNS: So the the question about getting HDMI cables with a 90 degree connected.

528
00:50:27.240 --> 00:50:31.300
SBU CFNS: but they, I think we were told, the connected was parallel to the

529
00:50:35.470 --> 00:50:38.010
Christopher J Vidal: so they make. They do make both.

530
00:50:39.030 --> 00:50:44.230
Christopher J Vidal: They make up to make, they make them so that it yeah, they make them bending both ways

531
00:50:44.540 --> 00:50:47.009
SBU CFNS: that that would help them. I think

532
00:50:47.790 --> 00:50:52.350
SBU CFNS: I was gonna ask while we're here.

533
00:50:52.670 --> 00:51:00.750
SBU CFNS: are these boards on? Hold both along sides of this, or only on one side, and they're only one time, so we can go through this 180 degrees. Just points.

534
00:51:05.320 --> 00:51:16.400
SBU CFNS: It's 1, 2, 2 agents. it's on the same down the line, right? So by rotating this 180 degrees.

535
00:51:18.050 --> 00:51:20.609
SBU CFNS: So the walls are real hard living, right?

536
00:51:20.720 --> 00:51:37.990
SBU CFNS: We can see you see 2 canvas back on each other right now. You could flip one over a lot of both the and so that you have the the short side still. But the long side it's in on the other side. So

537
00:51:38.080 --> 00:51:50.860
SBU CFNS: there there are 2 concerns. One is the shielding wall, and are we still imagining it's a single she'll be involved in it. Wasn't that much space in between? Yeah. So why not point these?

538
00:51:51.000 --> 00:51:52.929
SBU CFNS: Well, we'll see. We'll see.

539
00:51:53.070 --> 00:51:53.879
Okay.

540
00:51:54.710 --> 00:52:02.109
SBU CFNS: You cannot point them to the middle for both of them, because then for one of them, the

541
00:52:02.430 --> 00:52:06.330
SBU CFNS: they're not the only

542
00:52:06.500 --> 00:52:07.299
what

543
00:52:11.970 --> 00:52:18.360
SBU CFNS: the the you that's the that's the catch.

544
00:52:18.730 --> 00:52:23.430
SBU CFNS: But I think the the

545
00:52:28.400 --> 00:52:30.810
SBU CFNS: so.

546
00:52:30.900 --> 00:52:34.830
SBU CFNS: So 2 of

547
00:52:35.790 --> 00:52:38.699
SBU CFNS: So I have been thinking that to avoid the magnet.

548
00:52:38.940 --> 00:52:49.809
SBU CFNS: or sorry to to avoid extending the we flip one of them, so that both these long cards face in, and you point that you can't do that, because then the short end car and the link magnet

549
00:52:50.050 --> 00:52:52.959
SBU CFNS: good now I that makes sense to me.

550
00:52:53.100 --> 00:52:55.920
SBU CFNS: But you can turn it upside down.

551
00:52:56.440 --> 00:52:59.220
SBU CFNS: Oh, yeah, and that moves the poker plane

552
00:52:59.690 --> 00:53:09.699
SBU CFNS: and the window or something you said.

553
00:53:10.080 --> 00:53:13.569
Yeah.

554
00:53:14.530 --> 00:53:21.850
SBU CFNS: you want the

555
00:53:22.250 --> 00:53:25.060
SBU CFNS: but

556
00:53:25.210 --> 00:53:27.880
SBU CFNS: wait, wait, wait. The the castle

557
00:53:27.930 --> 00:53:30.470
SBU CFNS: is on top of that stack.

558
00:53:30.750 --> 00:53:35.590
SBU CFNS: and so you would need to. The cathode is going to face the

559
00:53:35.790 --> 00:53:37.470
window

560
00:53:38.670 --> 00:53:46.350
SBU CFNS: right? So they need to be flipped over compared to this view.

561
00:53:48.200 --> 00:53:48.779
Yeah.

562
00:53:49.010 --> 00:53:51.150
SBU CFNS: yeah, you have to figure that out.

563
00:53:51.170 --> 00:53:57.349
SBU CFNS: Yes, it was it incorrectly. But but I think the point is going to

564
00:53:58.330 --> 00:54:02.759
SBU CFNS: perpendicular to all connectors.

565
00:54:03.340 --> 00:54:11.580
SBU CFNS: They are on top of one another for the 2 layers, so that creates another problem with their. So who, when they work directly on top of each other

566
00:54:12.100 --> 00:54:14.419
so can you, can you?

567
00:54:14.660 --> 00:54:19.559
SBU CFNS: Well, so far we've not stacked up in the current design, they are aligned.

568
00:54:19.820 --> 00:54:23.450
SBU CFNS: so the holes on top of each other in the corners

569
00:54:24.080 --> 00:54:41.179
SBU CFNS: we couldn't displace some relatively. We don't, but then Chris is so strut scheme has to be what is fine. Yeah, but that that's pretty a new

570
00:54:41.290 --> 00:54:45.680
SBU CFNS: that threaded Rodriguez. is where crystal and that

571
00:54:45.790 --> 00:54:50.260
SBU CFNS: right? He had some bracket in here that then connects to the

572
00:54:50.630 --> 00:54:52.700
SBU CFNS: I get it. But it's all about them.

573
00:54:58.370 --> 00:55:00.709
SBU CFNS: otherwise we will not get all about. The

574
00:55:01.240 --> 00:55:03.040
SBU CFNS: is that already at the limit.

575
00:55:03.100 --> 00:55:10.239
SBU CFNS: Yes, thank you. Sh that by centimeter, just to get out of the way we have to 33 43 degree inclination.

576
00:55:10.280 --> 00:55:12.219
SBU CFNS: and that needs to be

577
00:55:13.120 --> 00:55:15.809
SBU CFNS: so. That's why it's

578
00:55:16.900 --> 00:55:22.109
SBU CFNS: but that doesn't send me your shift matter, because that's all you need to do, and get bring the table up

579
00:55:22.260 --> 00:55:24.730
SBU CFNS: parallel to each other so

580
00:55:24.750 --> 00:55:28.960
SBU CFNS: well. They they, their true centimeters apart, right

581
00:55:29.010 --> 00:55:34.070
SBU CFNS: and

582
00:55:34.830 --> 00:55:42.390
SBU CFNS: it, it will probably want to move the but through sending me it. So so okay. But we do that. Yeah, this aligned about 2 cm.

583
00:55:42.490 --> 00:55:45.849
SBU CFNS: You know this first of direction and then you solve the

584
00:55:46.250 --> 00:55:53.760
SBU CFNS: the space problem.

585
00:55:57.910 --> 00:55:58.910
SBU CFNS: These ones

586
00:55:59.380 --> 00:55:59.979
Yeah.

587
00:56:00.810 --> 00:56:05.419
SBU CFNS: Well, it's the Panosonic connectors of the Apv cards

588
00:56:05.540 --> 00:56:09.659
SBU CFNS: that are plugged on to. Do you see that here?

589
00:56:09.990 --> 00:56:11.169
SBU CFNS: hey? What you set up.

590
00:56:12.150 --> 00:56:16.019
SBU CFNS: These are fixed. They are on the readout board.

591
00:56:16.170 --> 00:56:18.090
So

592
00:56:18.940 --> 00:56:24.190
SBU CFNS: you! You wanted to adapt us again, or we try to avoid this for any means.

593
00:56:25.510 --> 00:56:33.440
SBU CFNS: So with this the IP card on, you see a little closer picture, and so the Apb cards are plugged onto these on a zoning connectors.

594
00:56:33.980 --> 00:56:41.370
SBU CFNS: but you find some to be in the same plane

595
00:56:41.570 --> 00:56:43.399
SBU CFNS: 20 cm

596
00:56:43.840 --> 00:56:46.000
SBU CFNS: on either. On day long

597
00:57:00.730 --> 00:57:11.970
SBU CFNS: we we have a solid model of of the German frames, but not of the electronics. If you can sketch it up, and we can see, you know, in

598
00:57:11.990 --> 00:57:31.300
SBU CFNS: where those factors fall tells us whether we just throw a bunch of running Hg: mind on that. If we don't it Well, no, it's there's but they they can't be stacked. That's what the honest point is, they have to be staggered. They have to be staggered if you have one going up to one going down.

599
00:57:33.250 --> 00:57:37.060
SBU CFNS: But we can't do that

600
00:57:38.800 --> 00:57:43.189
SBU CFNS: right now you can see

601
00:57:44.920 --> 00:57:45.910
SBU CFNS: the

602
00:57:45.960 --> 00:57:55.280
SBU CFNS: A. Pv. Cards exist, and the back planes that all the a. P. Cards and places on the back planes.

603
00:57:55.720 --> 00:57:59.729
SBU CFNS: I don't know you cannot see this on this picture one maybe I have a better one.

604
00:57:59.870 --> 00:58:07.570
SBU CFNS: So you see, an Ipv count that sticks out here, and that's these backpacks are the

605
00:58:07.590 --> 00:58:20.499
SBU CFNS: they are. They are passive. we just design, and you will be back playing it, and maybe to sign one which is even longer than the other one, so that they are saying that.

606
00:58:24.160 --> 00:58:25.750
But we.

607
00:58:26.380 --> 00:58:35.440
SBU CFNS: if I ever say it correctly, we absolutely must stagger

608
00:58:35.550 --> 00:58:36.270
me

609
00:58:36.330 --> 00:58:48.780
SBU CFNS: that that's true for that, and sorry which one they they're not talking about. This little was Forget the little one. It's it's only about the 2 long ones.

610
00:58:48.880 --> 00:58:49.669
SBU CFNS: Yeah.

611
00:58:49.830 --> 00:58:51.369
SBU CFNS: at the very least we should

612
00:58:52.330 --> 00:58:58.519
SBU CFNS: spend an hour to lock up just where those HDMI connectors are on a.

613
00:58:58.800 --> 00:59:08.189
SBU CFNS: If the staggering allows to displace the HDMI sockets of the 2 layers

614
00:59:08.260 --> 00:59:13.910
SBU CFNS: more next to each other. Then you can have some angles cable coming out to me.

615
00:59:14.050 --> 00:59:28.669
SBU CFNS: I believe the honest point is, we can redesign that backlane. It's not got a whole lot going on. If that's true, if it'd be. If that fails, it doesn't need to sign the ball. But if that happens after we have a CAD model that tells us that you actually have a problem.

616
00:59:38.810 --> 00:59:39.509
SBU CFNS: Yeah.

617
00:59:42.180 --> 00:59:43.109
And

618
00:59:43.170 --> 00:59:46.169
SBU CFNS: okay, that that view that we're looking at. Now.

619
00:59:46.240 --> 00:59:48.259
SBU CFNS: that's the

620
00:59:48.800 --> 00:59:49.599
SBU CFNS: going on.

621
00:59:49.870 --> 00:59:59.380
SBU CFNS: Let's see. That's the back plane of the short side.

622
00:59:59.650 --> 01:00:08.099
SBU CFNS: Yeah, there, there, there's that little or that can be somewhere else.

623
01:00:08.140 --> 01:00:13.700
SBU CFNS: Don't go up or down, or to go to the site.

624
01:00:15.050 --> 01:00:21.139
SBU CFNS: I think they all come up to this. You mean the ones from this part, or which part are you?

625
01:00:23.040 --> 01:00:24.589
SBU CFNS: The the cable

626
01:00:25.220 --> 01:00:33.639
SBU CFNS: would go like this, and you plug it in like this. So it's it's a 90 degree craft not not going up or down. It's quite nice if we go like this.

627
01:00:34.000 --> 01:00:36.440
it would be parallel to the boss

628
01:00:36.710 --> 01:00:38.570
SBU CFNS: in plain

629
01:00:38.720 --> 01:00:46.950
SBU CFNS: I so so they they would still be a little bit out like this, but you wouldn't have the cable coming off. Okay, it would come out in this direction. You could turn it down

630
01:00:48.030 --> 01:00:51.689
SBU CFNS: that all exist. So I don't think this is a real problem. We can find the right here.

631
01:00:52.520 --> 01:00:56.929
SBU CFNS: Do we need the phone with something else?

632
01:00:57.740 --> 01:00:58.470
No.

633
01:00:58.820 --> 01:01:02.109
SBU CFNS: or we could stagger them in this, and

634
01:01:02.210 --> 01:01:09.610
SBU CFNS: that's a very good point. We can also just move them over to the

635
01:01:10.050 --> 01:01:11.509
SBU CFNS: I do well and go on.

636
01:01:11.550 --> 01:01:15.499
SBU CFNS: You can, if you start, or in both directions, supports going to get you for soon.

637
01:01:15.720 --> 01:01:18.129
SBU CFNS: because you have. They have a picnic.

638
01:01:18.320 --> 01:01:25.659
SBU CFNS: They're fixed together, and you Don't, have to be individually tested. We only have to adjust the pool of all. So i'm asking, how do you?

639
01:01:25.780 --> 01:01:31.710
SBU CFNS: So you have to have one who's at the the core the 10 quarter one's gonna be over the

640
01:01:31.960 --> 01:01:33.560
SBU CFNS: Yeah, I to send you guys.

641
01:01:33.720 --> 01:01:35.060
SBU CFNS: So it's this thing.

642
01:01:36.790 --> 01:01:39.520
SBU CFNS: Yes, you can support that.

643
01:01:39.690 --> 01:01:40.259
Okay.

644
01:01:41.340 --> 01:01:46.660
SBU CFNS: yeah, in the longest possible coordinate. We have 20, or for that space.

645
01:01:46.860 --> 01:01:48.980
SBU CFNS: I imagine that I would agree.

646
01:01:53.490 --> 01:01:56.180
SBU CFNS: It just needs.

647
01:01:56.340 --> 01:02:07.710
SBU CFNS: Yeah, that's that's a very good one. You look out the vertical stagger if you do this by with the okay. So this this is not the Redesign Board. Even in the worst case we're

648
01:02:07.840 --> 01:02:17.429
SBU CFNS: with the

649
01:02:17.700 --> 01:02:20.689
SBU CFNS: the

650
01:02:20.760 --> 01:02:26.300
SBU CFNS: so so we can it be a shop on one side? We can move them all over a little bit.

651
01:02:26.550 --> 01:02:30.769
SBU CFNS: and and that's a that's a good point in that

652
01:02:30.860 --> 01:02:31.930
SBU CFNS: the the

653
01:02:32.080 --> 01:02:39.359
SBU CFNS: the real size we're worry about is the gym plus the read out on one side. Yeah. And you didn't even consider that.

654
01:02:39.570 --> 01:02:43.010
Yeah.

655
01:02:43.070 --> 01:02:46.990
SBU CFNS: you don't. You have that much in the April?

656
01:02:47.040 --> 01:02:47.600
Yeah.

657
01:02:48.410 --> 01:02:51.179
SBU CFNS: Then, Chris, Can you call them all up?

658
01:02:51.470 --> 01:03:02.130
Christopher J Vidal: Oh, yeah, yeah, I following it. Yeah. And have you ever known me to be happy about anything.

659
01:03:02.910 --> 01:03:13.010
SBU CFNS: we're working with us. But I I think, Michael Chris, you should give Chris the exact size of those boards.

660
01:03:13.470 --> 01:03:16.069
SBU CFNS: so that you can put that in a while

661
01:03:16.200 --> 01:03:22.410
SBU CFNS: correct.

662
01:03:22.490 --> 01:03:27.989
Christopher J Vidal: And if you want me to play around with with staggering them and and redoing the

663
01:03:28.060 --> 01:03:45.189
Christopher J Vidal: the brackets that hold them. That's not a problem, you know. I I can play around staggering out, and Ernie just Ernie just pointed out to me. You can get right angle. HDMI connectors. Yes, we we've already. We've already said that they they They go in all directions. You can get them going

664
01:03:45.370 --> 01:03:48.669
Christopher J Vidal: to left or right. Are you gonna go up going up or down?

665
01:03:53.190 --> 01:03:55.720
Ernie I: These? These had cables connected to them, too?

666
01:03:56.690 --> 01:03:57.600
Christopher J Vidal: Yeah.

667
01:03:57.850 --> 01:04:04.180
Christopher J Vidal: Not talking about adaptives. I'm talking about the tables themselves with it with their

668
01:04:04.220 --> 01:04:05.450
Ernie I: just want to point that out.

669
01:04:05.620 --> 01:04:09.420
Christopher J Vidal: because they don't want to use an adaptive because that just puts another

670
01:04:10.660 --> 01:04:25.129
SBU CFNS: another connection in there, and they they might also be able to modify the board. So I don't have different sockets that are already angle instead of if we don't want to buy all the tables.

671
01:04:30.490 --> 01:04:35.960
SBU CFNS: I have the schematics of the back.

672
01:04:36.690 --> 01:04:44.349
SBU CFNS: I think so. I can see what i'm.

673
01:04:44.810 --> 01:04:45.580
SBU CFNS: No

674
01:04:46.230 --> 01:04:51.339
SBU CFNS: the same.

675
01:04:51.620 --> 01:04:59.509
SBU CFNS: We have a good supply of.

676
01:05:01.770 --> 01:05:02.660
SBU CFNS: No.

677
01:05:02.800 --> 01:05:06.340
SBU CFNS: I would go to.

678
01:05:06.680 --> 01:05:20.249
SBU CFNS: So that's a that. There are the Imf versions of the Apb hybrid cards that have a different connector. They have this connectors and the uva content.

679
01:05:20.360 --> 01:05:27.379
SBU CFNS: And now that was the idea to reuse some of the unused ap<unk>,

680
01:05:27.790 --> 01:05:39.540
SBU CFNS: and make an adapter from good to one of only, and then the savings was making. That adapter is as expensive as making you.

681
01:05:42.420 --> 01:05:50.629
SBU CFNS: I don't know if it's the connectors that we see.

682
01:05:50.930 --> 01:05:51.620
Well.

683
01:05:57.540 --> 01:05:58.169
SBU CFNS: okay

684
01:06:06.130 --> 01:06:08.210
switch.

685
01:06:08.820 --> 01:06:11.650
SBU CFNS: It's easily in the most

686
01:06:18.290 --> 01:06:19.770
SBU CFNS: redesign.

687
01:06:21.250 --> 01:06:24.369
SBU CFNS: and you could even design the board with the same of

688
01:06:24.930 --> 01:06:35.979
Christopher J Vidal: if you were going to redesign the board, I mean, which, right off the top of my head, my first thought would be to redesign the board itself, so it mounts 90 degree to the

689
01:06:36.180 --> 01:06:37.999
Christopher J Vidal: to the gym.

690
01:06:38.110 --> 01:06:41.240
Christopher J Vidal: and you don't have to stagger.

691
01:06:41.820 --> 01:06:48.630
Christopher J Vidal: You don't need the bank connectors. You can just run everything parallel

692
01:06:48.640 --> 01:07:02.970
SBU CFNS: and not quite, though No, it's it's it's it's not. It's the board in the to the gym. I mean. That would also mean that we have to we? We're already talking about shifting the gyms. You know, a couple of centimeters.

693
01:07:02.980 --> 01:07:13.210
SBU CFNS: No, I I would be to the I if if I if if she wants to renew.

694
01:07:13.260 --> 01:07:14.710
SBU CFNS: That's very simple.

695
01:07:41.000 --> 01:07:55.859
SBU CFNS: Alright, okay, I think that's yeah, that's that's pretty much what I have. All right. I can put the pictures on the

696
01:07:55.890 --> 01:08:01.590
SBU CFNS: now that it is 2, 45. It is time for our 2 Pm.

697
01:08:01.690 --> 01:08:07.299
SBU CFNS: Talk. But I think, more importantly, we need to make some sort of.

698
01:08:07.360 --> 01:08:14.399
SBU CFNS: I don't want to adjust the timing here at least gonna plow through.

699
01:08:14.540 --> 01:08:16.990
SBU CFNS: You know we are. We are seriously behind here

700
01:08:18.939 --> 01:08:19.940
the number of

701
01:08:21.729 --> 01:08:26.059
SBU CFNS: So what at least one thing is, if Kate, if you

702
01:08:26.100 --> 01:08:30.530
SBU CFNS: if we push yours back. The net bush came back which pushes the back.

703
01:08:30.760 --> 01:08:44.189
SBU CFNS: Don't worry the second I've actually been with the students. Yeah. So i'd rather they get the chance to talk, so I suggest we move, and we can't go anything that Mike's to. My My son has been

704
01:08:45.060 --> 01:08:48.889
SBU CFNS: so we could talk about all the

705
01:08:49.279 --> 01:08:53.080
SBU CFNS: Can we just go on.

706
01:08:53.149 --> 01:09:05.020
Christopher J Vidal: Ross? I could. I could make a suggestion. Okay, My My portion of talking about shielding is really

707
01:09:05.090 --> 01:09:07.210
Christopher J Vidal: minimal. I mean, it's just

708
01:09:07.350 --> 01:09:11.000
Christopher J Vidal: I need to. Yeah create some kind of a table that will hold

709
01:09:11.040 --> 01:09:15.809
Christopher J Vidal: the weight of the shielding. I don't even need to do a talk on that. I don't really have anything.

710
01:09:16.420 --> 01:09:26.760
SBU CFNS: If you have a picture, and you want to just show it now and then we'll just. We'll knock that out, because then everything else is people this room, and you can.

711
01:09:26.770 --> 01:09:46.480
SBU CFNS: which those around will need to. I mean, literally, if you just see my screen. Now. Yeah, yeah, we'll keep them in the same place.

712
01:09:46.490 --> 01:09:47.770
And this is

713
01:09:48.189 --> 01:09:49.559
SBU CFNS: well, I mean.

714
01:09:49.819 --> 01:09:50.820
SBU CFNS: yeah, I think

715
01:09:51.800 --> 01:09:53.969
SBU CFNS: I think this is overkill, and

716
01:09:54.000 --> 01:09:57.949
SBU CFNS: as I understand it, Chris, you've designed this to do

717
01:09:58.300 --> 01:10:03.120
SBU CFNS: Jim a maximum for the way

718
01:10:03.130 --> 01:10:25.660
Christopher J Vidal: exactly that which which I really was gonna say is i'm designing something that is, that is okay. That is as much weight as I can think might need to be put on there and just make sure that the structure will support it when it comes to actual shielding. I think it's you're gonna have a table, and you're going to stack up what you need on it

719
01:10:25.670 --> 01:10:36.109
Christopher J Vidal: as long as it it can accommodate. Sky, shine all the way around and from the Chamber itself, then is that for foriated poly Chris.

720
01:10:36.680 --> 01:10:51.609
Christopher J Vidal: there isn't no oriented quality. It's all over it's. It's it a one, you know. Is it? It's a totally yeah. But but the only thing that i'm doing this for is to get the mass to hand off to

721
01:10:51.790 --> 01:10:54.000
Christopher J Vidal: people that are smarter than me that can

722
01:10:54.200 --> 01:10:56.509
Christopher J Vidal: tell me whether it'll support it or not.

723
01:10:56.530 --> 01:11:03.910
SBU CFNS: Is that actually the my son doesn't it?

724
01:11:04.140 --> 01:11:08.559
SBU CFNS: can you? I don't believe that. Can you make that disappear

725
01:11:09.120 --> 01:11:12.969
SBU CFNS: that your computer offers?

726
01:11:13.040 --> 01:11:17.959
Christopher J Vidal: What do you? What do you want to see there. You want to just see inside.

727
01:11:17.990 --> 01:11:20.580
SBU CFNS: yeah, I won't. Actually it all.

728
01:11:20.600 --> 01:11:27.829
SBU CFNS: Yeah or no, I take it, take the weight off all the all the the shielding off.

729
01:11:27.990 --> 01:11:33.290
SBU CFNS: you'll see it.

730
01:11:34.360 --> 01:11:35.900
SBU CFNS: Just make a smaller comment.

731
01:11:42.720 --> 01:11:45.460
Christopher J Vidal: Is that good enough?

732
01:11:45.670 --> 01:11:50.450
SBU CFNS: Yeah, See? See in this design there isn't a floor.

733
01:11:51.020 --> 01:11:51.920
Christopher J Vidal: Correct.

734
01:11:52.210 --> 01:11:58.260
Christopher J Vidal: Okay, so what? What? What? I actually thought. I wanted to put in sheets

735
01:11:59.220 --> 01:12:00.309
Christopher J Vidal: down

736
01:12:01.080 --> 01:12:04.050
Christopher J Vidal: this way the shield from the

737
01:12:04.190 --> 01:12:07.059
Christopher J Vidal: change, if that would work. But

738
01:12:07.210 --> 01:12:12.299
Christopher J Vidal: to get a floor on there you gonna have to have it kind of exactly to the the dipole.

739
01:12:12.330 --> 01:12:13.549
SBU CFNS: Yeah. So you

740
01:12:16.660 --> 01:12:18.889
SBU CFNS: Can you remove all the white

741
01:12:23.390 --> 01:12:26.100
SBU CFNS: doing it in panel by now.

742
01:12:27.150 --> 01:12:29.369
Christopher J Vidal: Yeah, I just have to grab them all at once.

743
01:12:29.400 --> 01:12:30.340
SBU CFNS: Yeah.

744
01:12:36.980 --> 01:12:38.330
SBU CFNS: Then I that.

745
01:12:40.020 --> 01:12:40.830
Yeah.

746
01:12:41.900 --> 01:12:45.250
SBU CFNS: So I yeah, the the struct certified.

747
01:12:45.300 --> 01:12:49.119
SBU CFNS: So what I would do is I would put a plate

748
01:12:49.190 --> 01:12:52.830
SBU CFNS: across at the level of the

749
01:12:53.220 --> 01:12:56.990
Christopher J Vidal: which is what this level of that right now

750
01:12:57.030 --> 01:13:04.219
SBU CFNS: right so for the you know, for a plate that goes all the way across the top of the magnets.

751
01:13:04.930 --> 01:13:13.889
SBU CFNS: and then we we just come along, and we stack up all the ethylene for Gorge and poly

752
01:13:15.520 --> 01:13:17.779
SBU CFNS: and then they need to have both side.

753
01:13:18.090 --> 01:13:22.180
Jim Kelsey: No, Doug, I mean we. You have to tell me what you're putting on it.

754
01:13:24.390 --> 01:13:29.689
SBU CFNS: So we're going to put on about 4 inches of cory and all the after it.

755
01:13:30.250 --> 01:13:33.539
SBU CFNS: and maybe a cent or a stick. No lead.

756
01:13:33.960 --> 01:13:44.469
SBU CFNS: No, I've been able to. But now that is too much. Yeah, let's let's say, an eighth of an inch of what I'm going to do with it?

757
01:13:44.650 --> 01:13:46.709
Jim Kelsey: And how are you going to support that?

758
01:13:47.250 --> 01:13:58.189
SBU CFNS: How are you going to support the lead? If it's well, actually, I would sandwich the lead between 2 sheets of sale with

759
01:13:58.340 --> 01:14:10.539
SBU CFNS: you can actually contact cemented to one of the sheets of poly also. That's what they could do in the Atlantic world, and then they get attached to the the Scots that in place.

760
01:14:16.360 --> 01:14:18.370
SBU CFNS: But I would, You know, I

761
01:14:18.520 --> 01:14:25.220
SBU CFNS: I think this the this octagon that Chris is on is bigger than what we will name.

762
01:14:25.280 --> 01:14:32.229
SBU CFNS: and that if we can get a table we can.

763
01:14:37.830 --> 01:14:41.389
Jim Kelsey: So who's doing the who's doing the simulations on this.

764
01:14:42.250 --> 01:14:53.210
Richard G Milner: What simulations shielding simulation! Yeah, there there should be a jay on calculation of all of this being into the foil. And and Cal, you know.

765
01:14:53.290 --> 01:14:58.289
Richard G Milner: And I think we've seen results from Jay and output after the target.

766
01:14:58.400 --> 01:15:03.110
Richard G Milner: But I agree with Jim. You. We need some in from just trying to randomly

767
01:15:03.270 --> 01:15:16.390
SBU CFNS: design this thing without any input or simulation doesn't make any sense. It's something that to get started with the guy, you know.

768
01:15:16.440 --> 01:15:23.279
SBU CFNS: Yeah, I got science on that. Yeah, that that's the next talk, right? Oh, okay, you're working on it. You run it. Okay, cool.

769
01:15:23.300 --> 01:15:34.209
Richard G Milner: Yeah. So I I would. I would wait until we have some informed idea of where what the background is, where it's where it is, and then, you know, you can put anything anywhere. What enough?

770
01:15:34.460 --> 01:15:36.799
Richard G Milner: I think we're just. We're just kind of

771
01:15:37.210 --> 01:15:39.139
Richard G Milner: thinking loud

772
01:15:39.230 --> 01:15:43.409
Christopher J Vidal: on this, which is fine. We're just fine up to a point, you know. But

773
01:15:43.480 --> 01:15:56.090
Christopher J Vidal: i'm trying to get it. I'm trying to get it.

774
01:16:07.080 --> 01:16:11.300
SBU CFNS: Okay, I think we've seen enough of this.

775
01:16:11.370 --> 01:16:12.330
SBU CFNS: and we're

776
01:16:12.930 --> 01:16:15.720
SBU CFNS: we'll go on. We need you to. Yeah.

777
01:16:17.250 --> 01:16:26.000
SBU CFNS: see if I do. Yeah. So thanks for us. We have the Mike and Kate. Yeah, let's do my

778
01:16:26.530 --> 01:16:27.790
and

779
01:16:27.940 --> 01:16:28.860
never

780
01:16:31.350 --> 01:16:34.570
SBU CFNS: shield that correct.

781
01:16:34.960 --> 01:16:40.110
SBU CFNS: Oh, I got it. You're You're gonna service. Sometimes, you guys.

782
01:16:40.500 --> 01:16:49.140
SBU CFNS: it should be 2 slides. It was under Kate's this background.

783
01:16:55.050 --> 01:16:56.219
SBU CFNS: Where is

784
01:16:57.100 --> 01:17:02.080
SBU CFNS: It's not up on zoom.

785
01:17:04.650 --> 01:17:08.589
SBU CFNS: And it's down there

786
01:17:09.310 --> 01:17:15.280
SBU CFNS: not this one. It's here. And then this is 41 yeah.

787
01:17:15.390 --> 01:17:16.560
SBU CFNS: back on this one

788
01:17:18.320 --> 01:17:21.289
SBU CFNS: not on. I actually got to get rid of this

789
01:17:26.080 --> 01:17:26.660
it works

790
01:17:26.860 --> 01:17:30.990
SBU CFNS: Well, what to trash.

791
01:17:31.550 --> 01:17:32.610
SBU CFNS: okay, there we go.

792
01:17:39.020 --> 01:17:40.260
SBU CFNS: Very well. Okay.

793
01:17:40.480 --> 01:17:46.329
SBU CFNS: So I won't. Use the pointer because it's too sold in tracking. So what we've done is some

794
01:17:47.230 --> 01:17:54.399
SBU CFNS: measurements of the neutron and gamma ray background in the area. Okay. So on the

795
01:17:54.530 --> 01:18:07.590
SBU CFNS: the part picture on the bottom we put small handheld dosimeters. I'll show you a picture of those in a minute inside a a house made up of 3, 7 point, 5 centimeters of lab.

796
01:18:07.770 --> 01:18:16.130
SBU CFNS: and and then we had we. We put together some scrap a little bit, and we built a a shield there.

797
01:18:16.330 --> 01:18:36.130
SBU CFNS: looking towards the felt. Here I put a monitor inside our trigger centimeters here that we've been using for an as well as 2 coincidence and a monitor in front of this Zoom in here. and then we covered that with another inch of aluminum. Okay, we also have an inch on the bottom.

798
01:18:36.140 --> 01:18:55.510
SBU CFNS: Okay? And then the measurements. The final business. I'll show you here. It's with a 2 and a half centimeters polyphony block that we found that try it, and then about a centimeter thick that cylinder here, and then I put a cover of it. I'll send it to your butt on top. Okay. So there's a monitor

799
01:18:55.520 --> 01:19:01.200
SBU CFNS: here and along over here. So I I have inside no shielding and then she'll

800
01:19:01.540 --> 01:19:04.989
SBU CFNS: different configurations.

801
01:19:05.320 --> 01:19:10.839
Ernie I: We're getting a lot of feedback through. I don't know, is our other people.

802
01:19:11.830 --> 01:19:14.870
Ernie I: I Your talk is coming through fine, but there's background

803
01:19:15.440 --> 01:19:16.499
where you are.

804
01:19:16.720 --> 01:19:24.229
SBU CFNS: I think there's some of somebody else. If you're great the Christian gym or on you.

805
01:19:24.940 --> 01:19:30.390
SBU CFNS: They've been on me with the day, but they're saying each other now physically. They might be changing it better now.

806
01:19:32.500 --> 01:19:35.070
SBU CFNS: Yes, very much. So. Okay. So

807
01:19:35.160 --> 01:19:47.320
SBU CFNS: here is we. We're using these Mary on as a French company that makes these handheld dosimeters with people who carry around they they. We have a neutron monitor that's that's included in it.

808
01:19:47.330 --> 01:19:56.560
SBU CFNS: So we they measure not very much information about them, except to say that the Gamma range that they measure is 15 kilometers up to 7. Mev.

809
01:19:56.660 --> 01:20:02.290
SBU CFNS: And the neutron range is from thermal neutrons to 10 to the minus 8 mev

810
01:20:02.330 --> 01:20:06.610
SBU CFNS: point 0 2 ev all the way up to 15,

811
01:20:07.030 --> 01:20:08.859
SBU CFNS: so they give us an integrated

812
01:20:08.880 --> 01:20:10.030
SBU CFNS: those

813
01:20:10.140 --> 01:20:13.850
SBU CFNS: rate per minute that we can read out. Okay.

814
01:20:14.440 --> 01:20:15.290
SBU CFNS: So

815
01:20:15.500 --> 01:20:33.190
SBU CFNS: here is are the results inside the 7 and a half mill centimeter led house. They can on the seventh of November 29.2; that sometimes they run the machine at 2235, 29, 8, and the power level here is up to a boat.

816
01:20:33.660 --> 01:20:35.319
SBU CFNS: 1 point, 4 kilowatts.

817
01:20:35.540 --> 01:20:37.490
SBU CFNS: Okay. So the

818
01:20:38.100 --> 01:20:41.900
SBU CFNS: the red lines are the power. The scale is on the right

819
01:20:42.140 --> 01:20:57.249
SBU CFNS: the green is when the gun. The electron gun is is on or not so that doesn't tell us very much. And then the blue dots on the read out of the the neutron clocks on the left, and the gamma clocks on the right.

820
01:20:58.230 --> 01:20:59.799
SBU CFNS: Okay. So you're in the dumb

821
01:21:00.560 --> 01:21:02.529
SBU CFNS: here. That's the top line.

822
01:21:02.650 --> 01:21:04.819
SBU CFNS: Okay, that there's new trucks

823
01:21:04.860 --> 01:21:10.469
SBU CFNS: and the gamma flocks on the right, the new trucks on the left. And what I did is, I calculated

824
01:21:10.890 --> 01:21:16.780
SBU CFNS: the the flux here per kilowatt per square centimeter per second.

825
01:21:17.110 --> 01:21:26.930
SBU CFNS: Okay. So we've converted from the the Millie siever per hour that the the device reads out back into a dose a flux rate.

826
01:21:27.390 --> 01:21:43.049
SBU CFNS: Assuming, I think it was 1 one Mev neutrons. And was it 5? One for both? Okay, this factor of 2 difference in the gamma conversion rate between one and 5 is what I do call, so you can see that we've got

827
01:21:43.100 --> 01:21:44.939
SBU CFNS: near the dough

828
01:21:45.640 --> 01:21:49.979
SBU CFNS: here we've got a 4, 40 and and

829
01:21:50.110 --> 01:21:52.790
SBU CFNS: neutrons, and we've got

830
01:21:53.340 --> 01:22:01.349
SBU CFNS: 5.6 kilohertz for gamma. And if we're closer to the prior module here the fluxes were lower.

831
01:22:01.700 --> 01:22:02.389
SBU CFNS: Okay.

832
01:22:04.310 --> 01:22:18.369
SBU CFNS: I had a picture of where they were, so the summary is here. I took the ratio for neutrons. The dump rate is 13 times the prior rate that the closer to the the cryo module and the gamma rays below 7 times

833
01:22:19.840 --> 01:22:38.510
SBU CFNS: the problem is that When when you look here at 1,300 h Here they're doing something, putting in a target and and measuring some things that are not recorded in the log. Very well. So so all I know is that when they say stable beam running it, you know so much

834
01:22:38.520 --> 01:22:52.980
SBU CFNS: 10% duty factor, 5% duty factor. I could then take a regional rate and say, this is what we would have under running. So that's where I I did this point here and here around 1,400 h

835
01:22:53.060 --> 01:22:57.009
SBU CFNS: rather than the high point here at $1,300,

836
01:22:57.120 --> 01:23:04.169
SBU CFNS: and because they're doing something and it's independent of the

837
01:23:05.090 --> 01:23:05.990
SBU CFNS: yeah.

838
01:23:06.130 --> 01:23:11.469
SBU CFNS: because they're not always delivering, being or accelerating the yeah. Okay. So we

839
01:23:11.680 --> 01:23:15.560
SBU CFNS: We had to to use the calculate the beam power.

840
01:23:15.690 --> 01:23:16.440
What's that?

841
01:23:17.260 --> 01:23:20.169
SBU CFNS: Okay? So Here's the 2 point, 5 cm.

842
01:23:20.800 --> 01:23:22.090
SBU CFNS: a little bit of shielding.

843
01:23:22.370 --> 01:23:28.890
SBU CFNS: Okay, this is done in October seventh, different beam energy. and here again.

844
01:23:29.350 --> 01:23:31.909
SBU CFNS: well, actually, Here you see the full range

845
01:23:31.990 --> 01:23:43.309
SBU CFNS: here from 1230 to 6 to 1,700, I guess. And then here is the expanded range where where we zoomed in and there I covered up the earlier range with the zoom.

846
01:23:43.530 --> 01:24:02.709
SBU CFNS: so we calculated here the power again at this point here, just before 4 o'clock, where they told us that they were running stable beam for 10 or 15 min, and you could see that the power goes up, and then it's sort of black. when when we

847
01:24:02.720 --> 01:24:04.620
SBU CFNS: here things are tracking pretty well

848
01:24:04.990 --> 01:24:05.670
right

849
01:24:05.900 --> 01:24:09.269
SBU CFNS: do I take this and this? There's more neutron flux

850
01:24:09.830 --> 01:24:14.740
SBU CFNS: with the

851
01:24:14.800 --> 01:24:15.530
see?

852
01:24:16.960 --> 01:24:18.320
SBU CFNS: this is outside

853
01:24:18.690 --> 01:24:20.800
SBU CFNS: is 260 electrons.

854
01:24:20.940 --> 01:24:24.139
SBU CFNS: and here it's

855
01:24:24.200 --> 01:24:25.179
SBU CFNS: 88.

856
01:24:25.930 --> 01:24:28.330
SBU CFNS: Okay, so Factor 3.

857
01:24:30.100 --> 01:24:34.710
SBU CFNS: This is this is so get a factor. 3 if we're inside behind the shared.

858
01:24:34.770 --> 01:24:41.249
SBU CFNS: Yeah, but so did it. Doesn't matter

859
01:24:41.430 --> 01:24:44.000
SBU CFNS: if you go back to your previous plots

860
01:24:44.020 --> 01:24:45.920
you were seeing of your

861
01:24:46.860 --> 01:24:49.300
SBU CFNS: one

862
01:24:50.520 --> 01:25:02.750
SBU CFNS: this is 7. It is 7 and a half centimeters a web. Oh, this is 8. 8. Sorry. Okay, this is. This is different different modules, but they they have a set of lead. The the

863
01:25:02.770 --> 01:25:04.999
SBU CFNS: the 3 80 had led around it.

864
01:25:06.100 --> 01:25:08.680
SBU CFNS: this is yes.

865
01:25:08.740 --> 01:25:16.639
SBU CFNS: this is led the both inside when done it, if they're just in different locations. Okay. But this is

866
01:25:16.740 --> 01:25:27.290
SBU CFNS: in the next slide. 870 is not in science shilling. That's right. Okay, I I was doing. I thought I was doing apples. Now i'm like, No, you're not. This is crazy, but it's some shielding somewhere else, and this one might not tell him

867
01:25:27.380 --> 01:25:33.150
SBU CFNS: we we we just wouldn't need it. Can't compare to this, I I I I get it. Thank you. Okay. So so

868
01:25:38.230 --> 01:25:51.490
SBU CFNS: if you look look at side one When I built the house that was, that was a complete enclosure for 2 modules that I just put in a different place in the hall. Got it? Okay. But but now what I'm doing is, i'm doing shielded and on shielding got it. Okay.

869
01:25:53.310 --> 01:25:56.219
SBU CFNS: So Here's inside the shield. They outside the shield. They

870
01:25:56.560 --> 01:25:58.260
SBU CFNS: and then the ratio is 3.

871
01:25:58.300 --> 01:25:59.000
SBU CFNS: Okay.

872
01:25:59.900 --> 01:26:00.740
SBU CFNS: So

873
01:26:01.560 --> 01:26:12.769
SBU CFNS: this one here is the the third configuration that I did. I was trying to figure out how how well we could do with neutrons with this this 2 and a half centimeters of polyethylene here.

874
01:26:12.870 --> 01:26:19.160
SBU CFNS: and the the data that I took for normalization here is that that's $1,600 here.

875
01:26:22.360 --> 01:26:26.370
SBU CFNS: because otherwise they were doing other tests. But I didn't understand.

876
01:26:26.990 --> 01:26:29.030
SBU CFNS: So neutrons on the left again.

877
01:26:29.290 --> 01:26:36.900
SBU CFNS: and gamma's on the right, and they're 2 different locations. sorry here. The same location, both near the dome.

878
01:26:37.190 --> 01:26:39.009
SBU CFNS: but this is unshielded.

879
01:26:39.140 --> 01:26:40.989
SBU CFNS: Okay. And this one is shielded.

880
01:26:43.020 --> 01:26:45.219
SBU CFNS: and what you can see is

881
01:26:45.440 --> 01:26:49.250
SBU CFNS: here. We've got 4, 10 to the 3 and point 2.

882
01:26:50.930 --> 01:26:58.900
SBU CFNS: Okay. So the neutrons are knocked down a lot. Okay, the gam is now are 2, 10 to the fifth versus Point 9.

883
01:26:58.970 --> 01:27:00.050
SBU CFNS: Thank you.

884
01:27:01.200 --> 01:27:05.880
SBU CFNS: And so the the summary here is the this one in

885
01:27:05.920 --> 01:27:09.210
SBU CFNS: polyethylene is giving us about a factor of 20

886
01:27:09.290 --> 01:27:11.519
SBU CFNS: reduction in the neutron flux.

887
01:27:12.260 --> 01:27:12.820
Yeah.

888
01:27:14.000 --> 01:27:18.560
SBU CFNS: But an and this is 1 cm that is giving us about a factor of 3.

889
01:27:20.100 --> 01:27:21.099
So your name.

890
01:27:21.180 --> 01:27:22.719
SBU CFNS: Yeah.

891
01:27:23.250 --> 01:27:24.070
SBU CFNS: bye.

892
01:27:25.250 --> 01:27:32.420
SBU CFNS: But it's like actually other question is.

893
01:27:33.780 --> 01:27:38.659
SBU CFNS: they are more sense. They're most sensitive to yeah, right for this location.

894
01:27:40.460 --> 01:27:41.420
SBU CFNS: And

895
01:27:42.030 --> 01:27:44.329
SBU CFNS: that's one reason why I want to go to 6

896
01:27:44.410 --> 01:27:49.620
SBU CFNS: rather than 4 per per module

897
01:27:49.800 --> 01:27:50.719
SBU CFNS: But

898
01:27:52.740 --> 01:27:56.150
SBU CFNS: I I forget how many brads they can take, but we

899
01:27:56.330 --> 01:27:58.920
SBU CFNS: we use them in an experimented.

900
01:27:59.080 --> 01:28:04.739
SBU CFNS: not these ones. we. We use 1 one similar to the what to pay was using.

901
01:28:04.840 --> 01:28:17.730
SBU CFNS: we bought them back in 2,012 or 2,013 and we irradiated them a triumph. before we bought them. We we did a a instruction test, but we were. We did that with clients.

902
01:28:17.940 --> 01:28:20.459
SBU CFNS: Okay, and we found that they

903
01:28:20.990 --> 01:28:21.690
SBU CFNS: with

904
01:28:21.750 --> 01:28:33.500
SBU CFNS: the doses that we were giving them. We they would last this about a year, and and continues running at J. Parks, and we weren't worried but I forget the exact number, so that i'm getting i'm a little bit worried about

905
01:28:33.590 --> 01:28:37.510
SBU CFNS: the neutron rate that we have to. That's why I like the need for

906
01:28:37.600 --> 01:28:45.000
SBU CFNS: 4 inches of poly up in our 10 cm. We have to make sure that.

907
01:28:52.500 --> 01:28:58.800
SBU CFNS: Yeah, that's why we need the floor right? yeah. And and the top.

908
01:29:00.930 --> 01:29:02.080
SBU CFNS: Yeah, I

909
01:29:04.130 --> 01:29:13.130
SBU CFNS: Oh, and by the way, you know, Ernie says if you still want the I still want okay already. Did you hear that

910
01:29:14.390 --> 01:29:25.259
Ernie I: so? What happened is it fell through the cracks because the texts were busy. I don't know what I realized here the last week. I asked Doug whether you still needed it

911
01:29:25.290 --> 01:29:39.660
SBU CFNS: like I did like I did with the land building a complete house and putting the full seminar inside, I would like to do the same thing. Yeah, and we didn't. We cut off the block that we have.

912
01:29:39.870 --> 01:29:40.580
Ernie I: So

913
01:29:40.890 --> 01:29:44.789
SBU CFNS: I I guess I got this one out of out of order. This is to show you

914
01:29:45.050 --> 01:29:54.389
SBU CFNS: exact sort of to scale where where we put them. When I say near the dump, and you're the client lodge is where those concrete blocks were positioned on the floor.

915
01:29:59.010 --> 01:30:01.050
SBU CFNS: What did I want to show here?

916
01:30:06.600 --> 01:30:07.800
SBU CFNS: Oh.

917
01:30:08.060 --> 01:30:10.840
SBU CFNS: I guess this is just to show that the

918
01:30:11.350 --> 01:30:18.059
SBU CFNS: this is on shielded. Okay, there's no shielding at all. We just put the do seminar 8 70 is near the dump.

919
01:30:18.090 --> 01:30:21.640
SBU CFNS: A 75 is near the Crime office. And this is the room background.

920
01:30:21.860 --> 01:30:28.950
SBU CFNS: and basically the racial is is about 18 to 20.

921
01:30:30.170 --> 01:30:36.470
SBU CFNS: So there's many more neutrons and many more gamma rays at the Belt location, and that's where we're going to be sitting.

922
01:30:37.090 --> 01:30:41.939
SBU CFNS: So because I was worried that the you know there's electron emission

923
01:30:41.970 --> 01:30:44.960
SBU CFNS: that that we see right with the high rate of

924
01:30:45.730 --> 01:30:52.149
SBU CFNS: X-rays or gamma rays was was near the the crime larger but but we're we're we're so.

925
01:30:52.610 --> 01:30:53.340
Oh.

926
01:30:53.600 --> 01:30:54.700
SBU CFNS: is awesome.

927
01:30:54.800 --> 01:30:56.869
SBU CFNS: If you look at this here.

928
01:30:57.080 --> 01:31:02.129
SBU CFNS: you see that this rise in blue here is shifted from the rise in red

929
01:31:02.270 --> 01:31:06.600
SBU CFNS: by about 10 min, so it looks like one of the

930
01:31:06.650 --> 01:31:10.440
SBU CFNS: timing was off in in the way we

931
01:31:10.670 --> 01:31:13.240
SBU CFNS: the the we get are the

932
01:31:13.320 --> 01:31:19.389
SBU CFNS: neutron monitors that we get we Haven't figured out how to set the clock in the app, and

933
01:31:19.770 --> 01:31:23.510
SBU CFNS: I think the cycle of people are getting the thought timing right, but

934
01:31:23.550 --> 01:31:42.560
SBU CFNS: I don't know about this module. So here again we were using 870 and 875 and some days they had a different one. We asked for a new module. So when you do your averaging average over a long period of time, you're not worried about that. Well, what I do is typically I take take this one here, and and I. I take

935
01:31:42.570 --> 01:31:47.310
SBU CFNS: the the little pieces here. I take the average, and then I just take the power here about 1.7.

936
01:31:47.350 --> 01:31:48.119
The problem.

937
01:31:53.960 --> 01:31:57.880
I think.

938
01:31:57.960 --> 01:31:58.670
Let's see.

939
01:31:59.560 --> 01:32:03.879
SBU CFNS: Yeah, I but let me. If these each have an internal clock

940
01:32:03.900 --> 01:32:07.330
SBU CFNS: and you're you're trying to find for the ratio of

941
01:32:07.380 --> 01:32:10.089
SBU CFNS: Then you know where you?

942
01:32:10.250 --> 01:32:11.050
Yeah, yeah.

943
01:32:11.340 --> 01:32:13.539
SBU CFNS: I I'm doing that by hand, right? Okay.

944
01:32:16.260 --> 01:32:19.279
SBU CFNS: So here, here again you can see the time shift.

945
01:32:19.400 --> 01:32:22.980
SBU CFNS: It's it's just going out, and I don't know

946
01:32:23.030 --> 01:32:25.980
SBU CFNS: the red data is being produced.

947
01:32:26.060 --> 01:32:33.389
SBU CFNS: okay, you are. They giving us every minute, and they're just spotting it, or they give you every 5 min.

948
01:32:41.150 --> 01:32:42.569
SBU CFNS: So here again.

949
01:32:44.350 --> 01:32:51.599
SBU CFNS: they should. It's fairly consistent if you're on children and children in the 2 locations, 15 to 20

950
01:32:53.000 --> 01:32:59.029
SBU CFNS: and and here this is, you know again, a 3 h period. This is a very nice period of the

951
01:32:59.110 --> 01:33:00.510
here.

952
01:33:00.570 --> 01:33:01.939
SBU CFNS: or at least we got it

953
01:33:02.010 --> 01:33:03.169
SBU CFNS: close to an hour.

954
01:33:03.290 --> 01:33:04.740
SBU CFNS: our stable running.

955
01:33:11.040 --> 01:33:17.839
SBU CFNS: This one one of the very highest power. We got 6 kilowatts at 60% duty factor.

956
01:33:18.650 --> 01:33:23.719
SBU CFNS: And so again, you can see that it's quite stable here, others

957
01:33:24.080 --> 01:33:28.530
SBU CFNS: neutron activation and gamma activation. As I was reading it in the

958
01:33:28.570 --> 01:33:32.850
SBU CFNS: the report that that we sent to the to the

959
01:33:33.330 --> 01:33:41.220
SBU CFNS: Licensing Agency. so you could see the activation here that the neutron flux is falling here

960
01:33:41.490 --> 01:33:42.940
SBU CFNS: after the beam goes on.

961
01:33:56.530 --> 01:33:59.290
SBU CFNS: well, this these numbers are for Kilowatt.

962
01:33:59.530 --> 01:34:03.729
SBU CFNS: Oh, I've normalized

963
01:34:03.980 --> 01:34:07.160
that the clock is is

964
01:34:08.110 --> 01:34:08.750
yeah.

965
01:34:11.160 --> 01:34:14.210
SBU CFNS: So the the prime modules are just

966
01:34:14.790 --> 01:34:16.340
SBU CFNS: glowing forever.

967
01:34:17.140 --> 01:34:30.660
SBU CFNS: Is that how it

968
01:34:30.950 --> 01:34:33.349
stays near the

969
01:34:33.780 --> 01:34:47.959
So yeah. Basically

970
01:34:47.990 --> 01:34:49.840
So you're still ahead. In the Middle Ages

971
01:34:50.480 --> 01:35:01.470
SBU CFNS: the green line is supposedly telling us that there's our

972
01:35:02.090 --> 01:35:03.100
It does seem to

973
01:35:04.150 --> 01:35:08.840
SBU CFNS: we, before we were trying to correlate that we we're having trouble until we correlated with power.

974
01:35:09.740 --> 01:35:12.860
SBU CFNS: You know there's the getting all the way to the Belt.

975
01:35:14.090 --> 01:35:16.389
SBU CFNS: So and here

976
01:35:17.440 --> 01:35:19.470
SBU CFNS: this is an interesting one. Here

977
01:35:19.600 --> 01:35:20.689
SBU CFNS: you can have us

978
01:35:20.740 --> 01:35:23.460
SBU CFNS: right. Being goes off here

979
01:35:24.160 --> 01:35:26.059
SBU CFNS: and look at this one.

980
01:35:28.110 --> 01:35:34.980
SBU CFNS: So change the prior module still has our app, I guess, and and it's still making

981
01:35:35.360 --> 01:35:39.449
SBU CFNS: something here here in the cloud module, where, as you're in the down

982
01:35:40.120 --> 01:35:42.489
SBU CFNS: it it's followed by a factor of 10

983
01:35:42.690 --> 01:35:43.650
that you

984
01:35:43.940 --> 01:35:47.289
SBU CFNS: very naively it looks like something for around 12,

985
01:35:47.350 --> 01:35:55.020
SBU CFNS: 40, 1245 that actually causes the the dump to see something in the gambas and neutrons jump

986
01:35:55.310 --> 01:36:02.460
SBU CFNS: I don't. I don't understand this this peak here.

987
01:36:02.730 --> 01:36:03.500
Yeah.

988
01:36:03.930 --> 01:36:05.190
SBU CFNS: But whatever it

989
01:36:07.370 --> 01:36:09.400
SBU CFNS: yeah, this is our problem.

990
01:36:10.550 --> 01:36:13.620
That's good to see that the

991
01:36:18.740 --> 01:36:22.820
SBU CFNS: And I think.

992
01:36:26.680 --> 01:36:33.669
SBU CFNS: yeah, we may. We may have to get some more concrete blocks down there and shield the the crowd modules from our, in fact, 3

993
01:36:33.700 --> 01:36:41.279
SBU CFNS: in direct line of site, and that should be possible. So here, what did I want to show here?

994
01:36:42.090 --> 01:36:48.279
SBU CFNS: again? This is no shielding near the dumb near the and now

995
01:36:48.460 --> 01:36:59.979
SBU CFNS: The rates are a little different, but you can see that it it's tracking quite well here again. went down, and then we go up again, even though the time is shifted a little bit. I account for that.

996
01:37:02.930 --> 01:37:07.279
SBU CFNS: and then you can see the fluctuations in the in the power level.

997
01:37:15.940 --> 01:37:29.719
SBU CFNS: you know they it only recorded, or if it's off scale. You see, this is a few 10 report, either.

998
01:37:29.730 --> 01:37:44.979
SBU CFNS: and if it goes down below you you wouldn't see. I think we're talking about the neutrons we've also had. Sometimes the battery goes dead. But I don't think that's the case here. I think it's just that it's gone off scaling it so it's down here.

999
01:37:48.040 --> 01:38:00.280
SBU CFNS: So that's that's your faulting routine. I think it's it's it's just been great, but that these I don't counting statistics. Like I saw one neutron I saw 2 neutrons.

1000
01:38:00.490 --> 01:38:14.619
but in that situation

1001
01:38:15.340 --> 01:38:15.920
bye bye.

1002
01:38:19.880 --> 01:38:22.910
SBU CFNS: back again.

1003
01:38:23.680 --> 01:38:29.310
SBU CFNS: this this way, I mean. You can see there's other things going on, because here there's a factor of 200.

1004
01:38:30.030 --> 01:38:35.130
SBU CFNS: It's between the dump location and and the the the

1005
01:38:39.210 --> 01:38:40.650
SBU CFNS: Yeah. Well, this was

1006
01:38:40.840 --> 01:38:46.859
SBU CFNS: 6. That's 7 kilowatts with almost 100 on right. So

1007
01:38:47.770 --> 01:38:49.100
SBU CFNS: I don't know

1008
01:38:49.220 --> 01:38:52.669
what when we

1009
01:38:56.790 --> 01:38:58.269
Well.

1010
01:38:58.640 --> 01:39:03.189
SBU CFNS: no, but I that's what we want to run that 150 micro apps

1011
01:39:03.290 --> 01:39:05.400
SBU CFNS: at a 100%.

1012
01:39:05.600 --> 01:39:07.330
So

1013
01:39:21.110 --> 01:39:23.970
it's hard to.

1014
01:39:30.320 --> 01:39:31.240
So

1015
01:39:31.490 --> 01:39:36.340
I think we have.

1016
01:39:46.410 --> 01:39:54.449
Yeah.

1017
01:40:04.150 --> 01:40:06.540
SBU CFNS: this one's even more confusing.

1018
01:40:09.220 --> 01:40:10.250
SBU CFNS: So

1019
01:40:10.630 --> 01:40:14.600
SBU CFNS: here we have. I'm shielded and shielded. This is the

1020
01:40:14.720 --> 01:40:18.890
SBU CFNS: 1 one age poly after me, 1 cm lab and

1021
01:40:19.400 --> 01:40:23.590
SBU CFNS: The rates are all over the place, and I don't understand what happened here.

1022
01:40:25.850 --> 01:40:31.189
SBU CFNS: It's it's it's it's in both the gamma and the

1023
01:40:31.210 --> 01:40:33.330
SBU CFNS: it would be no.

1024
01:40:33.600 --> 01:40:39.059
SBU CFNS: And yet, as you had to look, it's 10 to the Sixth.

1025
01:40:40.400 --> 01:40:46.849
SBU CFNS: Would it be that you're all in the time?

1026
01:40:47.030 --> 01:40:52.839
SBU CFNS: 10 min is, I think, the the worst we've seen where we blow it up?

1027
01:40:54.320 --> 01:40:55.070
SBU CFNS: Sorry.

1028
01:40:59.620 --> 01:41:16.579
SBU CFNS: What's that? This. Could you adjust your I don't know it's really looks like it's 2 to 2 of the Us. Okay.

1029
01:41:17.080 --> 01:41:21.640
SBU CFNS: Okay, October 10. I thought I had something in November, the seventh, or something.

1030
01:41:21.760 --> 01:41:26.050
SBU CFNS: It would be nice if that was just a solid hour off.

1031
01:41:26.150 --> 01:41:39.839
SBU CFNS: We got to be better than something happened, but nothing was on the

1032
01:41:40.130 --> 01:41:40.710
awesome.

1033
01:41:40.950 --> 01:41:55.380
SBU CFNS: Yeah, we have one. What I mean. We're running along and and Billy seabirds per hour, and all of a sudden we got one using micro super per hour, that they have 2 ranges. We didn't ask them to change it, but Simon, the data, and they're gone up by back in 1,000

1034
01:41:59.400 --> 01:42:05.750
SBU CFNS: if it does happen in that room. I never want to be okay. So

1035
01:42:07.270 --> 01:42:19.020
SBU CFNS: I I don't know right. You can look at the so that's what we got so far. Now, what I have found is a we had a large cylinder in class

1036
01:42:19.060 --> 01:42:21.970
SBU CFNS: that was 5 inches thick.

1037
01:42:22.530 --> 01:42:27.569
SBU CFNS: and I put that down there, and we took an 8, or on Thursday. I think

1038
01:42:28.040 --> 01:42:29.949
that we haven't we haven't looked that way.

1039
01:42:30.240 --> 01:42:33.309
SBU CFNS: so we are not in front of the for them.

1040
01:42:39.460 --> 01:42:41.970
SBU CFNS: Okay, we have a question. Richard, you a question.

1041
01:42:42.950 --> 01:42:51.670
Richard G Milner: Yeah, First of all, that this this is very nice. I mean it's in general, it seems to make sense. My question was, if one takes the

1042
01:42:51.870 --> 01:42:57.280
Richard G Milner: fluxes of neutrons and gammas say shielded, I don't know 100 for neutrons and

1043
01:42:57.910 --> 01:43:06.010
Richard G Milner: 100,000, or something like for Gammas. So can we then kind of make an informed estimate as to how that will affect the detectors?

1044
01:43:06.450 --> 01:43:15.839
Richard G Milner: It needs some knowledge of the of the energy distribution, and and how the detectors will respond to these particles. But I I mean that seems to me

1045
01:43:16.160 --> 01:43:17.750
Richard G Milner: an interesting question.

1046
01:43:18.570 --> 01:43:36.949
SBU CFNS: we have data that we've taken with the scintillators that you saw down there. So we we recorded at other times, and sometimes at the same time the rates and the individual scintillators that are 8 by 20 cm squared.

1047
01:43:38.040 --> 01:43:44.680
SBU CFNS: and we we've got both the singles and the coincidence rates. I think the highest I've seen is about 3,000 counts

1048
01:43:44.770 --> 01:43:46.900
SBU CFNS: per square centimeter per second

1049
01:43:48.320 --> 01:44:04.179
SBU CFNS: in later, so I haven't yet tried to calculate the efficiency for a neutron or a bone time going through 3 so yeah, I mean on the face of it. Also, it doesn't seem that bad. But maybe I'm: not the

1050
01:44:04.750 --> 01:44:12.900
SBU CFNS: yeah, I mean, our. The one thing is, our our Sims are only 3 by $3.

1051
01:44:13.000 --> 01:44:17.000
Richard G Milner: Right?

1052
01:44:17.160 --> 01:44:17.900
Richard G Milner: Yeah.

1053
01:44:18.950 --> 01:44:26.859
Richard G Milner: yeah. I mean, the other thing is what it would do to the gems. I don't know if any gems are fire, or either these particles and trends or photons. I don't know

1054
01:44:27.450 --> 01:44:30.020
Richard G Milner: that's not very efficient.

1055
01:44:41.240 --> 01:44:43.710
And when we

1056
01:44:44.580 --> 01:44:45.469
SBU CFNS: well.

1057
01:44:45.860 --> 01:44:51.380
SBU CFNS: your, your, your, your, your your Vm. A cream is going to have to sit down on the floor.

1058
01:44:51.620 --> 01:45:08.350
SBU CFNS: I I do have David Coll, that we're we very first time we're brand new, and in August. I did, and I was a dumper ship, but we we had one go similar, and it was down on the floor

1059
01:45:08.400 --> 01:45:12.450
SBU CFNS: and the

1060
01:45:13.710 --> 01:45:15.549
but I I don't have.

1061
01:45:16.140 --> 01:45:18.239
SBU CFNS: and he should actually move.

1062
01:45:21.130 --> 01:45:22.280
SBU CFNS: Yeah.

1063
01:45:51.330 --> 01:45:52.869
SBU CFNS: we'll see you stop.

1064
01:45:53.000 --> 01:46:06.309
SBU CFNS: I mean, I mean, yeah. Well, of course, you know. But all the electrons coming from the

1065
01:46:13.030 --> 01:46:14.140
SBU CFNS: that's all I have. Actually

1066
01:46:14.490 --> 01:46:16.429
SBU CFNS: any other questions on the line.

1067
01:46:18.320 --> 01:46:23.140
SBU CFNS: I would propose that we take a 15 min off of grade.

1068
01:46:23.350 --> 01:46:27.129
SBU CFNS: and that means that we will start 5 min late with,

1069
01:46:39.160 --> 01:46:39.920
SBU CFNS: all right.

1070
01:46:40.730 --> 01:46:44.730
SBU CFNS: So does whoever that is. Now.

1071
01:46:47.660 --> 01:46:51.709
SBU CFNS: Okay, okay, perfect. And then it will be story. And then I think

1072
01:46:52.190 --> 01:47:02.200
SBU CFNS: so. Can we give it a full 15 min and service a little bit past 345

1073
01:47:02.640 --> 01:47:06.239
SBU CFNS: it up to 15 min.

1074
01:47:06.740 --> 01:47:07.480
SBU CFNS: Yeah.

1075
01:47:07.940 --> 01:47:12.570
SBU CFNS: coffee cookies

1076
01:47:13.670 --> 01:47:26.040
SBU CFNS: lang

1077
01:47:36.750 --> 01:47:37.340
Good.

1078
01:47:47.760 --> 01:47:52.899
SBU CFNS: Oh, I don't know

1079
01:47:59.650 --> 01:48:01.029
I could just

1080
01:48:07.320 --> 01:48:07.929
yes.

1081
01:48:08.720 --> 01:48:10.239
SBU CFNS: i'm on the phone along.

1082
01:48:10.440 --> 01:48:14.029
SBU CFNS: and he was not there on Saturday, so I I

1083
01:48:14.360 --> 01:48:19.949
SBU CFNS: got it from

1084
01:48:20.190 --> 01:48:22.699
SBU CFNS: I didn't say before I was a different guy.

1085
01:48:23.270 --> 01:48:25.279
SBU CFNS: and that was, we need support.

1086
01:48:25.590 --> 01:48:26.870
SBU CFNS: yeah, what not?

1087
01:48:27.760 --> 01:48:36.030
SBU CFNS: No, no, no, it's it's actually that I was saying it was my.

1088
01:48:36.330 --> 01:48:37.230
thank you.

1089
01:48:38.940 --> 01:48:42.170
SBU CFNS: It's like an over gas station.

1090
01:48:42.220 --> 01:48:43.700
SBU CFNS: and

1091
01:48:50.240 --> 01:48:52.109
SBU CFNS: and they have they had their cost in.

1092
01:48:52.610 --> 01:48:56.299
SBU CFNS: Okay, so sorry I I

1093
01:48:56.700 --> 01:49:01.489
SBU CFNS: that's not. I get this taste like an expensive dental procedure.

1094
01:49:08.830 --> 01:49:09.690
SBU CFNS: So.

1095
01:49:11.160 --> 01:49:12.809
SBU CFNS: you guys blue here.

1096
01:49:16.640 --> 01:49:17.540
SBU CFNS: what are you?

1097
01:49:18.340 --> 01:49:20.789
SBU CFNS: Maybe we should try that.

1098
01:49:42.430 --> 01:49:43.619
SBU CFNS: What we do?

1099
01:49:43.710 --> 01:49:46.620
We have little 200 cookies that we need

1100
01:49:49.170 --> 01:49:50.540
right now

1101
01:50:15.670 --> 01:50:16.750
that this line

1102
01:50:17.580 --> 01:50:18.919
we need this one.

1103
01:50:23.180 --> 01:50:24.429
It's like

1104
01:50:29.040 --> 01:50:31.580
SBU CFNS: It seems that we do a lot of

1105
01:50:32.070 --> 01:50:33.479
I on the numbers.

1106
01:50:56.080 --> 01:50:57.420
SBU CFNS: No problem.

1107
01:51:09.950 --> 01:51:10.740
SBU CFNS: Yeah.

1108
01:51:45.730 --> 01:51:47.780
300,

1109
01:51:53.670 --> 01:51:58.320
SBU CFNS: probably.

1110
01:52:04.270 --> 01:52:05.219
or anything.

1111
01:52:05.890 --> 01:52:07.139
SBU CFNS: That is what we

1112
01:52:07.860 --> 01:52:09.590
SBU CFNS: slightly worse.

1113
01:52:18.540 --> 01:52:19.590
SBU CFNS: It wasn't

1114
01:52:57.630 --> 01:53:00.669
SBU CFNS: It's crazy to do an experiment in the email.

1115
01:53:04.210 --> 01:53:05.249
SBU CFNS: How are you doing?

1116
01:53:13.890 --> 01:53:14.440
Yup.

1117
01:53:23.180 --> 01:53:23.830
Yeah.

1118
01:53:46.440 --> 01:53:47.179
yeah.

1119
01:53:54.250 --> 01:54:04.629
SBU CFNS: yeah.

1120
01:54:30.690 --> 01:54:42.489
SBU CFNS: that's my

1121
01:54:42.510 --> 01:54:43.600
one or 2.

1122
01:55:04.900 --> 01:55:23.770
SBU CFNS: Okay.

1123
01:55:28.470 --> 01:55:29.210
right.

1124
01:55:30.160 --> 01:55:36.179
SBU CFNS: We should

1125
01:55:42.410 --> 01:55:51.069
SBU CFNS: that that we will be able to do with the new board that we're in design, and we want to

1126
01:55:52.500 --> 01:55:53.240
so

1127
01:55:54.550 --> 01:55:56.110
SBU CFNS: That would be good.

1128
01:56:22.360 --> 01:56:24.420
That's true.

1129
01:56:24.590 --> 01:56:30.490
SBU CFNS: At first we

1130
01:56:35.360 --> 01:56:35.940
bye bye.

1131
01:56:55.250 --> 01:56:56.119
SBU CFNS: Sorry about that.

1132
01:57:01.670 --> 01:57:06.839
SBU CFNS: It probably, but it's set together so much that it's only one.

1133
01:57:07.060 --> 01:57:11.580
SBU CFNS: That's

1134
01:57:14.120 --> 01:57:15.529
so. I I don't

1135
01:57:16.550 --> 01:57:26.270
SBU CFNS: it's a it's a it's a it's it's it's it's it's it's a good question

1136
01:57:26.290 --> 01:57:34.200
SBU CFNS: it was like, Make a binary search for

1137
01:57:34.500 --> 01:57:37.760
SBU CFNS: If you could explain what the code did.

1138
01:57:37.830 --> 01:57:45.369
SBU CFNS: Okay, how to implement the yeah, it's a pretty classic problem. So

1139
01:57:45.430 --> 01:57:48.240
SBU CFNS: it it's weird that seems like this.

1140
01:57:48.720 --> 01:58:04.119
SBU CFNS: it's what we' from alcohol always want it to be. I don't know if you ever have a big

1141
01:58:04.160 --> 01:58:11.600
SBU CFNS: yeah, this this an open AI chat. You can describe it. I mean it's like a

1142
01:58:12.340 --> 01:58:14.199
SBU CFNS: It's basically a chat box.

1143
01:58:16.400 --> 01:58:19.160
SBU CFNS: They just take database back in 2,021,

1144
01:58:19.380 --> 01:58:22.469
SBU CFNS: where you can basically ask it if anything properly.

1145
01:58:23.770 --> 01:58:34.910
SBU CFNS: i'll tell you a story about this.

1146
01:58:35.440 --> 01:58:37.750
SBU CFNS: I don't know I tech table.

1147
01:58:37.830 --> 01:58:40.939
SBU CFNS: and it's right.

1148
01:58:49.290 --> 01:58:54.130
SBU CFNS: Yeah.

1149
01:58:54.300 --> 01:59:12.409
SBU CFNS: yeah, I like, we're in an all programming assignment.

1150
01:59:12.420 --> 01:59:16.190
SBU CFNS: this son. Finally, I understand. You generate a.

1151
01:59:27.950 --> 01:59:29.000
and

1152
01:59:48.720 --> 01:59:50.979
at least by decoding also. Again.

1153
01:59:55.370 --> 02:00:00.550
SBU CFNS: Yeah.

1154
02:00:09.580 --> 02:00:12.619
SBU CFNS: So

1155
02:00:17.220 --> 02:00:19.670
okay.

1156
02:00:29.180 --> 02:00:34.459
SBU CFNS: I don't know where to.

1157
02:00:34.570 --> 02:00:35.900
SBU CFNS: I just

1158
02:00:35.960 --> 02:00:45.269
SBU CFNS: yeah, go ahead. So yeah, we have about an hour and 4.

1159
02:00:45.310 --> 02:00:50.240
SBU CFNS: Some discussion.

1160
02:00:55.840 --> 02:00:58.059
You be able to share your screen with,

1161
02:00:59.780 --> 02:01:02.870
yeah, I also have Doug: do you want any?

1162
02:01:03.150 --> 02:01:06.150
So

1163
02:01:07.250 --> 02:01:08.859
SBU CFNS: yeah.

1164
02:01:09.370 --> 02:01:12.170
like the slides?

1165
02:01:17.920 --> 02:01:18.550
Okay.

1166
02:01:21.420 --> 02:01:31.050
SBU CFNS: So i'm changing, supervised by okay, and even then. Today I' to talk about the simulation of Atlantic.

1167
02:01:33.220 --> 02:01:36.229
SBU CFNS: So we have a catalog of the magnet

1168
02:01:36.360 --> 02:01:45.870
SBU CFNS: which was provided by Chris, and it compense the over to the provision, including coils, yokes, and back and chamber.

1169
02:01:46.030 --> 02:01:53.160
SBU CFNS: and the you know what's covered to a teapot and the

1170
02:01:54.180 --> 02:02:05.699
SBU CFNS: and here is a a visualization of the model in the beautiful, the magnes going forward to as a people.

1171
02:02:08.010 --> 02:02:08.670
hey?

1172
02:02:09.230 --> 02:02:13.210
SBU CFNS: So the team oil target, which is low here

1173
02:02:13.250 --> 02:02:27.449
SBU CFNS: and and the 2 vocal plans which are red. we're created, and there are 3 gem detectors, one in those 4 plan another one you don't look located on the 3 cm of.

1174
02:02:28.820 --> 02:02:34.250
SBU CFNS: So the set up in the simulation is the call away in the electron.

1175
02:02:34.420 --> 02:02:36.769
SBU CFNS: The angle between the electron specs familiar

1176
02:02:36.870 --> 02:02:44.620
SBU CFNS: like with the timeline, it's 51 degrees, and for the

1177
02:02:44.740 --> 02:02:57.569
SBU CFNS: and the the materials in Venezuela is following the 4 pcs at a yolks were made of iron and welcome chamber it's made of.

1178
02:02:57.580 --> 02:03:11.779
SBU CFNS: and the film that we used to what was provided by dog, and and then you would apply to the simulation through a trillion or interpolation, and the the open admin within the magnets also included.

1179
02:03:12.160 --> 02:03:16.879
SBU CFNS: and the we manage. We presume it's 31, and it'll be we have some teams.

1180
02:03:16.930 --> 02:03:24.870
SBU CFNS: and the the we chose for gamma Prime is 17 to 17, going the 0 one Mev.

1181
02:03:24.900 --> 02:03:33.279
SBU CFNS: And we've run the 1 billion people's 4 resolution, and the 30 annually will be electron.

1182
02:03:35.350 --> 02:03:39.770
SBU CFNS: we made the James to store his information.

1183
02:03:39.910 --> 02:03:48.189
SBU CFNS: So for the his data on the detectors we have X the.

1184
02:03:48.290 --> 02:03:59.579
SBU CFNS: and this person coordinates y and a stock Dx d one, and for the initially, initial check checks parameters. We have a moment that we

1185
02:03:59.630 --> 02:04:03.030
SBU CFNS: and you can go through that and all of the end of 5, so we met

1186
02:04:03.080 --> 02:04:09.049
SBU CFNS: It's more to is 3 to the transfer options.

1187
02:04:09.360 --> 02:04:21.810
SBU CFNS: The fi here is P or C number 5, and then we speak to the tracks to obtain the office here. with with the strong limitations on the allow, the combinations of the

1188
02:04:22.040 --> 02:04:27.080
SBU CFNS: and then we recover the most of the

1189
02:04:27.210 --> 02:04:32.820
SBU CFNS: to.

1190
02:04:33.390 --> 02:04:36.610
SBU CFNS: So we've all the hand of the

1191
02:04:38.610 --> 02:04:40.720
SBU CFNS: the first to roll here

1192
02:04:41.040 --> 02:04:42.800
SBU CFNS: as a result of

1193
02:04:42.830 --> 02:04:44.779
SBU CFNS: we the body.

1194
02:04:45.010 --> 02:04:49.330
SBU CFNS: and then the second row is the result without my both scattering back.

1195
02:04:49.380 --> 02:04:53.489
SBU CFNS: and we can see that there, in the case of

1196
02:04:54.020 --> 02:05:10.239
SBU CFNS: that we have but for scary, but we have some tail events here, and I wish might be a close to 5 days in some that's been scheduled by this magnet, and then they hit the

1197
02:05:11.130 --> 02:05:12.830
SBU CFNS: So

1198
02:05:13.040 --> 02:05:16.429
SBU CFNS: question, okay, on the lower right?

1199
02:05:16.450 --> 02:05:19.850
SBU CFNS: Oh, the wide scale is different.

1200
02:05:21.150 --> 02:05:22.119
SBU CFNS: Yeah, I need to.

1201
02:05:22.400 --> 02:05:25.150
SBU CFNS: Yeah.

1202
02:05:25.590 --> 02:05:29.070
SBU CFNS: Yeah, here are the 2 plots of Why, I guess they

1203
02:05:29.260 --> 02:05:38.309
SBU CFNS: for the case. We don't multiple scheduling. We can see that it shows the initial the distribution of the left-hand side on the

1204
02:05:38.670 --> 02:05:39.540
SBU CFNS: and you

1205
02:05:39.670 --> 02:05:43.199
SBU CFNS: if if you named the sales

1206
02:05:43.780 --> 02:05:46.940
SBU CFNS: the same size as the downs

1207
02:05:49.380 --> 02:05:52.600
SBU CFNS: what's what's the size in general? It's

1208
02:05:52.690 --> 02:05:53.780
SBU CFNS: 25 by 40.

1209
02:06:00.310 --> 02:06:06.899
You zoom in.

1210
02:06:06.940 --> 02:06:13.280
SBU CFNS: Yeah, it's.

1211
02:06:14.180 --> 02:06:14.840
So.

1212
02:06:24.070 --> 02:06:24.900
Yeah.

1213
02:06:24.930 --> 02:06:28.400
SBU CFNS: So graceful.

1214
02:06:28.720 --> 02:06:30.429
SBU CFNS: Yeah.

1215
02:06:35.880 --> 02:06:36.740
Yeah.

1216
02:06:36.840 --> 02:06:39.969
SBU CFNS: Even the tables.

1217
02:06:40.150 --> 02:06:40.960
Okay.

1218
02:06:42.290 --> 02:06:43.929
SBU CFNS: And the

1219
02:06:44.050 --> 02:06:47.980
SBU CFNS: so

1220
02:06:48.250 --> 02:06:50.619
SBU CFNS: that's a clear way.

1221
02:06:52.200 --> 02:06:58.039
SBU CFNS: So so the situation in the

1222
02:06:58.630 --> 02:07:04.079
SBU CFNS: and the then we brand the resolution of with

1223
02:07:06.690 --> 02:07:08.960
SBU CFNS: I mean, it looks like if you look at this.

1224
02:07:09.220 --> 02:07:10.940
SBU CFNS: if we really use

1225
02:07:11.250 --> 02:07:14.510
SBU CFNS: plus minus 2 degrees the promise

1226
02:07:14.720 --> 02:07:16.580
SBU CFNS: it's when you' that back in right.

1227
02:07:16.710 --> 02:07:18.540
SBU CFNS: it's not that much

1228
02:07:20.920 --> 02:07:26.290
SBU CFNS: right? So so we would lose the extreme that the right size on this distribution.

1229
02:07:27.040 --> 02:07:29.500
SBU CFNS: and it's not all that hard.

1230
02:07:30.040 --> 02:07:31.730
SBU CFNS: So you didn't.

1231
02:07:36.990 --> 02:07:45.439
SBU CFNS: It would be really nice to see, plus your minus 2 degrees, not in this figure. They don't exactly how much it's

1232
02:07:45.600 --> 02:07:47.790
SBU CFNS: the full range.

1233
02:07:51.890 --> 02:07:54.880
SBU CFNS: And this this is all in that.

1234
02:07:55.670 --> 02:08:00.779
SBU CFNS: Yeah.

1235
02:08:05.130 --> 02:08:08.669
SBU CFNS: it'd be like, so today, future.

1236
02:08:08.800 --> 02:08:11.420
SBU CFNS: it'd be nice to see the X and y

1237
02:08:11.490 --> 02:08:13.729
SBU CFNS: block from the left

1238
02:08:13.940 --> 02:08:16.059
SBU CFNS: super post.

1239
02:08:16.130 --> 02:08:18.769
SBU CFNS: you know. Period that is, without

1240
02:08:19.520 --> 02:08:26.409
SBU CFNS: what we're scattering, going on because yeah, a lot of a lot of the extra width on the top, just because there's tails. They're down

1241
02:08:26.710 --> 02:08:28.859
SBU CFNS: noisy and low, but the actual

1242
02:08:29.150 --> 02:08:32.979
SBU CFNS: 4 of that doesn't think it's changing that much right?

1243
02:08:34.450 --> 02:08:39.719
SBU CFNS: Because this is this is why it's 50. This is minus 50,

1244
02:08:41.220 --> 02:08:43.260
SBU CFNS: so they're not. They're not that much.

1245
02:08:48.020 --> 02:08:48.900
The

1246
02:08:50.970 --> 02:08:51.679
Yeah.

1247
02:08:53.750 --> 02:08:56.070
And that's just the location.

1248
02:08:57.130 --> 02:08:57.860
No.

1249
02:09:00.890 --> 02:09:02.530
SBU CFNS: with the

1250
02:09:02.850 --> 02:09:04.829
you have an exponential.

1251
02:09:10.740 --> 02:09:21.320
SBU CFNS: Then we overturned the resolution of a, by which we thought about it about Kevin to see how the Pdm. Works.

1252
02:09:21.360 --> 02:09:33.860
SBU CFNS: and we can see that. that's more arrows for the moment I and angle for the results of the angle and slightly worse than the previously with the

1253
02:09:33.890 --> 02:09:39.390
SBU CFNS: and but we we we might be able to you this by

1254
02:09:39.490 --> 02:09:43.199
SBU CFNS: if you to see if there is a better position for the fourth plan.

1255
02:09:43.520 --> 02:09:44.219
What

1256
02:09:44.350 --> 02:09:46.939
SBU CFNS: may I ask? What what causes the

1257
02:09:47.460 --> 02:09:53.069
SBU CFNS: Sorry, but what causes this? This a little while to do, that on the in

1258
02:09:55.180 --> 02:10:03.050
SBU CFNS: it has a and and more than in the middle one secondary peak in it

1259
02:10:03.710 --> 02:10:05.759
SBU CFNS: They're streaming

1260
02:10:06.380 --> 02:10:13.859
SBU CFNS: well, I mean. One of them is 2 of them are shoulders, and one of them is a yeah. I guess they're they're all the same Need some of them

1261
02:10:14.610 --> 02:10:15.850
SBU CFNS: this what area

1262
02:10:16.180 --> 02:10:17.360
SBU CFNS: you know that comes from.

1263
02:10:19.130 --> 02:10:19.730
Okay.

1264
02:10:21.550 --> 02:10:40.800
SBU CFNS: it's actually one. So yeah. But what is plotting here? But what are the 2 curves? So the blue line is the real real that the the the yellow one. It is the, you know. So okay.

1265
02:10:40.810 --> 02:10:52.600
SBU CFNS: So what what you've done? The sales? Do you do the right to reconstruct the target values? Yeah. And then you also know the truth for the target that

1266
02:10:53.680 --> 02:10:54.480
SBU CFNS: right?

1267
02:10:54.560 --> 02:10:56.270
SBU CFNS: And here's the tracking listing.

1268
02:11:04.550 --> 02:11:05.570
SBU CFNS: So

1269
02:11:06.870 --> 02:11:11.599
SBU CFNS: it's a it's a

1270
02:11:11.660 --> 02:11:14.440
SBU CFNS: okay

1271
02:11:17.570 --> 02:11:25.469
SBU CFNS: right? It's it's the difference between the generated value of the target, you know, reconstructed that it? Yeah.

1272
02:11:35.010 --> 02:11:35.920
So I

1273
02:11:36.310 --> 02:11:47.120
SBU CFNS: I think this is. This is already more than Mary said. Anything else

1274
02:11:47.630 --> 02:11:52.820
SBU CFNS: in.

1275
02:11:53.160 --> 02:12:00.210
SBU CFNS: You have only so many digits in the Sp. 5. You you're right this this peak at point one and the in

1276
02:12:00.340 --> 02:12:02.870
SBU CFNS: that could be the

1277
02:12:03.320 --> 02:12:07.600
SBU CFNS: exactly right. They just don't have a

1278
02:12:14.860 --> 02:12:15.590
bye.

1279
02:12:16.320 --> 02:12:17.050
Yeah

1280
02:12:21.410 --> 02:12:28.369
SBU CFNS: the moment I me for the

1281
02:12:59.980 --> 02:13:00.690
you know.

1282
02:13:00.920 --> 02:13:01.820
Yeah.

1283
02:13:04.630 --> 02:13:20.710
that's all you get all of this. But again

1284
02:13:20.720 --> 02:13:27.050
SBU CFNS: it doesn't matter what this is, because as soon as it's been

1285
02:13:27.160 --> 02:13:30.820
SBU CFNS: I I see your point.

1286
02:13:31.340 --> 02:13:42.210
SBU CFNS: So it's your next

1287
02:13:47.340 --> 02:13:50.159
SBU CFNS: we just use the

1288
02:13:53.800 --> 02:13:56.979
SBU CFNS: Of course I think that I saw that maybe

1289
02:14:00.320 --> 02:14:00.980
I totally

1290
02:14:03.020 --> 02:14:12.569
SBU CFNS: so it it's it's some combination of X y, I T. X one, and maybe it's you know, a power one, and that's 2 in the line, one and Dx and

1291
02:14:12.670 --> 02:14:16.049
and then

1292
02:14:16.100 --> 02:14:20.590
SBU CFNS: it's it's it's a it's a huge it's a it's a

1293
02:14:20.630 --> 02:14:28.169
SBU CFNS: and on the

1294
02:14:35.140 --> 02:14:35.809
Okay.

1295
02:14:40.610 --> 02:14:41.800
SBU CFNS: which one of us

1296
02:14:45.860 --> 02:14:51.150
SBU CFNS: this is about multiple scattering. And this is going to be such a minor effect

1297
02:14:51.250 --> 02:14:56.009
SBU CFNS: that we don't really

1298
02:14:59.090 --> 02:15:00.820
SBU CFNS: that

1299
02:15:01.030 --> 02:15:06.650
SBU CFNS: the year bars are 10 times larger. Yeah. And now we don't care about this little.

1300
02:15:07.070 --> 02:15:07.939
SBU CFNS: I get it.

1301
02:15:08.580 --> 02:15:15.049
SBU CFNS: Yeah. And then the the reason of the end goes to a similar to the previous result

1302
02:15:15.410 --> 02:15:34.099
SBU CFNS: and the resolution of the moment that's back to the worst. they had a purpose, we thought, maybe because there is a

1303
02:15:39.380 --> 02:15:40.050
yeah.

1304
02:15:43.020 --> 02:15:46.580
SBU CFNS: I

1305
02:15:57.520 --> 02:15:59.289
SBU CFNS: I mean 2 degrees.

1306
02:15:59.310 --> 02:16:09.869
SBU CFNS: So we we have last lines, 500 meetings.

1307
02:16:10.230 --> 02:16:11.449
SBU CFNS: all our

1308
02:16:12.610 --> 02:16:15.500
SBU CFNS: hey? This is.

1309
02:16:16.340 --> 02:16:18.460
SBU CFNS: and then

1310
02:16:19.950 --> 02:16:24.190
SBU CFNS: I mean

1311
02:16:24.890 --> 02:16:28.260
SBU CFNS: about a 70 micrometers.

1312
02:16:38.170 --> 02:16:39.559
SBU CFNS: Sure, absolutely

1313
02:16:39.600 --> 02:16:40.430
that, you guys.

1314
02:16:45.940 --> 02:16:51.740
SBU CFNS: I I

1315
02:16:52.580 --> 02:16:53.730
We've set it to the

1316
02:16:57.010 --> 02:17:03.070
SBU CFNS: so. Then, for the of the

1317
02:17:11.299 --> 02:17:23.510
SBU CFNS: slightly we're standard. It's always we have added a button camera, or something for all the

1318
02:17:24.639 --> 02:17:25.820
for some reason.

1319
02:17:28.070 --> 02:17:30.740
SBU CFNS: So we've analyzed some

1320
02:17:31.070 --> 02:17:34.520
SBU CFNS: that's the that's the that's the

1321
02:17:34.690 --> 02:17:40.470
SBU CFNS: 330 into the Mac net and the schedule schedule of the

1322
02:17:40.490 --> 02:17:43.780
SBU CFNS: trigger the

1323
02:17:44.209 --> 02:17:51.919
SBU CFNS: and we we we we can see that in the first image which is the electron spectrometer. So the 30 iv like

1324
02:17:52.040 --> 02:18:00.749
SBU CFNS: but not first the people of the field, and they the the upper part of the welcome gender, and then they trigger the genes.

1325
02:18:00.940 --> 02:18:06.799
SBU CFNS: and for the second image is the the position of spectrometer. So the electron.

1326
02:18:06.840 --> 02:18:12.840
SBU CFNS: when the down first and then triggered the James. And this events

1327
02:18:12.980 --> 02:18:18.210
SBU CFNS: smaller than the

1328
02:18:18.230 --> 02:18:30.109
SBU CFNS: and the full run of 0 for the 1 million per month. We've got around the 10,000 events. I'm recording the license

1329
02:18:30.219 --> 02:18:32.399
SBU CFNS: I you

1330
02:18:34.030 --> 02:18:36.530
SBU CFNS: but for the

1331
02:18:36.920 --> 02:18:40.520
SBU CFNS: text, me by distributors in the

1332
02:18:41.219 --> 02:18:47.280
SBU CFNS: you like some spectrum available for both the, you know, and the everyone. They can see that the the Dx has

1333
02:18:50.799 --> 02:18:56.740
SBU CFNS: but the dy is so the divide of a signal, and the

1334
02:18:56.969 --> 02:19:02.269
SBU CFNS: via the ui from the

1335
02:19:02.480 --> 02:19:06.969
SBU CFNS: and so we they take some

1336
02:19:07.180 --> 02:19:10.309
SBU CFNS: we we use the of the

1337
02:19:11.350 --> 02:19:27.299
SBU CFNS: and that's for the additional spectrometer. It's also at a similar situation, that the the dy of the signal text has a negative pick, while the dy from the background is even at the

1338
02:19:29.020 --> 02:19:37.229
SBU CFNS: and the for the you already have the kind of acceptance we chose the a range of momentum of that left

1339
02:19:37.480 --> 02:19:38.530
SBU CFNS: I see

1340
02:19:38.790 --> 02:19:50.039
SBU CFNS: 55% to 1 45% of the central mob account. And we divided to 900 things with 15 min

1341
02:19:50.360 --> 02:20:06.360
SBU CFNS: it's the 0 point, 1% of central momentum and the Islamic go. Then we shows it's minus 3.5 degrees to 3.5 degrees, and the we have what it's

1342
02:20:06.380 --> 02:20:15.010
SBU CFNS: and all.

1343
02:20:19.040 --> 02:20:20.920
SBU CFNS: And then we follow the

1344
02:20:23.460 --> 02:20:28.059
SBU CFNS: Thank you very much. And so

1345
02:20:28.910 --> 02:20:35.539
SBU CFNS: for the call of planning go against the people angle. We thought, we can see that

1346
02:20:35.690 --> 02:20:37.590
SBU CFNS: in the

1347
02:20:38.000 --> 02:20:41.139
SBU CFNS: yeah, they are more even.

1348
02:20:41.330 --> 02:20:42.960
and that will be

1349
02:20:44.180 --> 02:20:47.589
SBU CFNS: auto plan. Go against the momentum.

1350
02:20:47.650 --> 02:20:51.669
SBU CFNS: we can see that in the

1351
02:20:53.450 --> 02:21:04.299
SBU CFNS: yeah Bo events here and for the momentum against the

1352
02:21:04.440 --> 02:21:07.349
SBU CFNS: the acceptance of England and those things.

1353
02:21:07.680 --> 02:21:17.310
SBU CFNS: And so the first role is for the

1354
02:21:17.340 --> 02:21:18.600
SBU CFNS: and the

1355
02:21:18.670 --> 02:21:21.969
SBU CFNS: they show that we have similar.

1356
02:21:22.760 --> 02:21:27.289
SBU CFNS: So

1357
02:21:44.600 --> 02:21:45.860
it's pretty well

1358
02:21:46.450 --> 02:21:49.240
SBU CFNS: are we seeing?

1359
02:21:53.480 --> 02:21:55.630
SBU CFNS: So the the hotspot at

1360
02:21:55.920 --> 02:22:08.490
SBU CFNS: out of that angle equals 0. Is that just a a convolution of you know rate increasing on one end of this, and the fact that on. I've already the acceptance. You will let me do local scatter out of the detector.

1361
02:22:22.620 --> 02:22:24.439
SBU CFNS: Oh, yeah, there are these white stripes.

1362
02:22:26.540 --> 02:22:32.830
SBU CFNS: So so how do you do. You kill tracks, the the vacuum chamber.

1363
02:22:33.020 --> 02:22:35.060
SBU CFNS: What can they reflect that you?

1364
02:22:35.940 --> 02:22:38.340
SBU CFNS: They can.

1365
02:22:38.600 --> 02:22:39.400
SBU CFNS: Okay.

1366
02:22:39.650 --> 02:22:42.839
SBU CFNS: because this looks like we accept tooling. We is everywhere right.

1367
02:22:44.460 --> 02:22:47.240
SBU CFNS: This looks like the except 2 degrees everywhere.

1368
02:22:47.540 --> 02:22:54.500
SBU CFNS: Oh, no, no! We see, we hear the checks. I think we kill the checks

1369
02:22:56.420 --> 02:22:57.280
fine.

1370
02:22:57.480 --> 02:23:00.399
but you're a little bit under this one

1371
02:23:01.610 --> 02:23:04.350
you're at like 108 here.

1372
02:23:04.420 --> 02:23:19.199
SBU CFNS: So again it depends on what directions we would have any, what bits you're missing, and these are the generated angles, and not every I believe so the angles we generated, the chat set, and then the mentioned. You generated the chat side. Yes, then we need to step back.

1373
02:23:19.330 --> 02:23:22.760
And it's basically

1374
02:23:22.950 --> 02:23:33.859
SBU CFNS: the legally things are especially so. So on momentum like it's way better than the 20% exactly expected. But yeah, it's closer to 30 and 65.

1375
02:23:40.870 --> 02:23:44.169
SBU CFNS: That is probably the size of the J.

1376
02:23:49.000 --> 02:23:49.699
yeah.

1377
02:23:49.840 --> 02:23:51.100
Are we getting the

1378
02:23:51.140 --> 02:23:59.959
SBU CFNS: I? I would think this is such a hard cut that looks like the

1379
02:24:00.060 --> 02:24:04.810
SBU CFNS: yeah. Yeah, yeah, yeah, exactly.

1380
02:24:15.260 --> 02:24:17.970
SBU CFNS: No. We just put more of our in.

1381
02:24:18.770 --> 02:24:20.030
SBU CFNS: Oh, that's

1382
02:24:20.060 --> 02:24:29.409
SBU CFNS: That's the other direction. So the 15 cm is essentially this: that's fine.

1383
02:24:32.750 --> 02:24:40.130
SBU CFNS: I think that's fine.

1384
02:24:43.840 --> 02:24:45.630
SBU CFNS: Yeah, so you're saying one.

1385
02:24:50.000 --> 02:24:55.940
SBU CFNS: I think it's more than 40, because it's gonna be above the second channel.

1386
02:24:56.560 --> 02:25:00.090
SBU CFNS: and the second time you will essentially use the all of it.

1387
02:25:00.540 --> 02:25:10.699
SBU CFNS: and it's IP. 31, 42,

1388
02:25:10.810 --> 02:25:11.400
okay.

1389
02:25:11.960 --> 02:25:14.799
SBU CFNS: and the length of the

1390
02:25:22.440 --> 02:25:32.689
SBU CFNS: so so that produces hits on both terms, for only in the first.

1391
02:25:41.680 --> 02:25:47.629
SBU CFNS: Oh, yeah, I think we've recorded that the you will that it can't keep the both both both terms. Yeah. Yeah. Okay.

1392
02:25:50.470 --> 02:25:51.869
SBU CFNS: They're already. Second.

1393
02:25:51.890 --> 02:25:54.730
SBU CFNS: Yeah, they they are ultimately thanks.

1394
02:26:02.530 --> 02:26:09.189
SBU CFNS: But then you can also ask.

1395
02:26:10.520 --> 02:26:12.230
SBU CFNS: is this: this is the

1396
02:26:13.130 --> 02:26:18.480
SBU CFNS: discrimination? Yeah, yeah, there is a back in 10,

1397
02:26:19.350 --> 02:26:20.769
so it gives you an idea.

1398
02:26:21.260 --> 02:26:23.960
SBU CFNS: So then, the

1399
02:26:28.190 --> 02:26:31.019
SBU CFNS: I believe this is the gems, because it's a shop

1400
02:26:32.300 --> 02:26:35.419
SBU CFNS: which is such a strong correlation between auto plane

1401
02:26:35.740 --> 02:26:37.280
SBU CFNS: and he.

1402
02:26:38.290 --> 02:26:51.449
SBU CFNS: But it's so flat in me. Oh, sorry, no, it's not. I'm looking at. I you know, in plain, able and saying so. I think you're right. Kate was right. Yeah, th this is come over the J. And this is probably the chamber.

1403
02:26:52.230 --> 02:26:54.070
SBU CFNS: I I think that

1404
02:26:57.530 --> 02:27:04.009
SBU CFNS: the Chamber will scrape off some things, but then Jen's will see. Cease to be at that point, and they cannot see anything.

1405
02:27:04.480 --> 02:27:07.010
SBU CFNS: I'm on my own.

1406
02:27:08.050 --> 02:27:10.840
SBU CFNS: This is low curvature so far into the jet One.

1407
02:27:11.700 --> 02:27:14.030
SBU CFNS: yeah, but i'm wondering

1408
02:27:14.060 --> 02:27:17.230
SBU CFNS: so so negative on the plane. It's not going down or going up.

1409
02:27:18.880 --> 02:27:24.450
SBU CFNS: So so it's it's a going going down. Yeah. Yeah.

1410
02:27:24.710 --> 02:27:28.959
SBU CFNS: So then I don't quite get that, because I would say.

1411
02:27:29.440 --> 02:27:31.880
SBU CFNS: if i'm going down more.

1412
02:27:32.020 --> 02:27:33.859
SBU CFNS: I should come back

1413
02:27:34.830 --> 02:27:39.689
SBU CFNS: with the angle flowing towards the target. So I should allow for higher dimension.

1414
02:27:43.220 --> 02:27:53.049
SBU CFNS: yeah, yeah, going down. If you're pointing down. Yeah, you're coming back it comes back. It goes through the focus, and then has

1415
02:27:53.370 --> 02:27:58.619
SBU CFNS: more talk, advice, position on the second job. In that case you're scraping off the chamber there

1416
02:28:00.000 --> 02:28:09.800
SBU CFNS: by, if it's if you go down with the angle and up with the momentum, you strike the chain. Yeah, so that is the right. So this must be a.

1417
02:28:15.610 --> 02:28:20.690
SBU CFNS: So, so we probably can get even more of that back if we make that.

1418
02:28:21.020 --> 02:28:21.660
Yeah.

1419
02:28:21.780 --> 02:28:26.220
SBU CFNS: what? Why is the ice

1420
02:28:27.560 --> 02:28:31.729
SBU CFNS: in the middle of the

1421
02:28:42.170 --> 02:28:42.740
Okay.

1422
02:28:47.680 --> 02:28:51.750
it was. Basically

1423
02:28:57.770 --> 02:29:11.059
SBU CFNS: that's that's strange, right it it should be constant density in in all will be IP. And everything. So it. Local scattering is randomization of your scattering able, which

1424
02:29:11.280 --> 02:29:15.189
SBU CFNS: it's a. It's it's it's it's more or less right

1425
02:29:15.640 --> 02:29:21.330
SBU CFNS: or no, i'm sorry it it's equal to the scattering same angle in the direction.

1426
02:29:21.470 --> 02:29:26.409
SBU CFNS: low momentum, and negative scattering.

1427
02:29:26.760 --> 02:29:35.679
SBU CFNS: So I I I mean it's I. I would say something he has to that 100% acceptance. Right? It's something you don't have 100% acceptance.

1428
02:29:35.710 --> 02:29:39.789
SBU CFNS: Yeah. And the density in these quantities should be constant

1429
02:29:40.240 --> 02:29:49.750
SBU CFNS: again, depending on how we generate it. I don't know the I don't know how many points to generate. How did you generate them? Did you generate them in these call units like?

1430
02:29:49.800 --> 02:29:51.799
SBU CFNS: What's the intensity in these walls?

1431
02:29:54.540 --> 02:29:56.030
SBU CFNS: Yeah.

1432
02:29:58.520 --> 02:30:04.679
SBU CFNS: But but in these coins, right in the space in P. And and not a plan. And

1433
02:30:05.070 --> 02:30:06.250
SBU CFNS: you mean the range.

1434
02:30:07.180 --> 02:30:14.510
SBU CFNS: No. How do you generate this? So you generate in these coordinates? Right? Yeah. So so it should be that right

1435
02:30:16.490 --> 02:30:18.910
SBU CFNS: now, I and you see it here. Yeah, that's that.

1436
02:30:18.980 --> 02:30:19.680
Yeah

1437
02:30:22.160 --> 02:30:25.710
SBU CFNS: it to me that makes life. Which is you. You're hired like

1438
02:30:25.780 --> 02:30:30.309
SBU CFNS: the output angles that are 0 are the ones that go down the center of the pipe.

1439
02:30:31.140 --> 02:30:34.110
SBU CFNS: They have the biggest tolerance of scattering

1440
02:30:34.310 --> 02:30:35.460
SBU CFNS: Okay, internally.

1441
02:30:35.990 --> 02:30:37.250
but i'm not

1442
02:30:39.720 --> 02:30:46.479
SBU CFNS: let's. Let's look at how cloud it is in in playing with angle versus momentum.

1443
02:30:46.850 --> 02:30:54.559
SBU CFNS: That's so. That's nice and flat. That suggests that was generating flat, and the output enable is generated in some other fashion.

1444
02:30:54.880 --> 02:30:56.430
SBU CFNS: But it should possibly be flat.

1445
02:30:57.140 --> 02:31:01.649
SBU CFNS: but it may be, and and it's certainly I mean you also have a great

1446
02:31:02.390 --> 02:31:04.779
SBU CFNS: but if we generated like the

1447
02:31:06.180 --> 02:31:13.350
SBU CFNS: you generated this with. Why, like it in spherical coordinates.

1448
02:31:13.460 --> 02:31:16.189
SBU CFNS: Maybe it's not out of there. Maybe it's fine.

1449
02:31:17.770 --> 02:31:19.700
SBU CFNS: This is a

1450
02:31:19.830 --> 02:31:24.030
SBU CFNS: that I don't think we need to address.

1451
02:31:29.840 --> 02:31:33.900
SBU CFNS: Yeah, but it it would be really long if you don't accept 100%,

1452
02:31:34.190 --> 02:31:38.210
SBU CFNS: right? So you know. So just divide by what you through

1453
02:31:38.300 --> 02:31:39.869
SBU CFNS: and each.

1454
02:31:41.020 --> 02:31:42.060
Okay.

1455
02:31:44.030 --> 02:31:51.170
SBU CFNS: but we are able to image the edges of the gem and or back in chamber, and that's good to see.

1456
02:31:52.460 --> 02:31:53.560
Okay, go on.

1457
02:31:54.030 --> 02:31:59.729
SBU CFNS: Okay. So we have.

1458
02:32:02.500 --> 02:32:07.240
SBU CFNS: So these are 3D plots, plus some density term that we can't see.

1459
02:32:07.380 --> 02:32:08.359
SBU CFNS: Is that right?

1460
02:32:08.790 --> 02:32:11.820
SBU CFNS: Yeah.

1461
02:32:13.800 --> 02:32:18.900
SBU CFNS: So basically, just trying to show you those 3.

1462
02:32:19.140 --> 02:32:20.250
Alright, but

1463
02:32:20.830 --> 02:32:22.099
SBU CFNS: really, I mean.

1464
02:32:22.870 --> 02:32:27.469
SBU CFNS: since you generated this volume, it should be. Either there is a plot, or there is no

1465
02:32:29.510 --> 02:32:30.260
SBU CFNS: like.

1466
02:32:30.620 --> 02:32:35.509
SBU CFNS: If either the top comes through or it's not coming through. Yeah, but you don't see the service. But

1467
02:32:35.990 --> 02:32:39.420
SBU CFNS: yeah, but that's I mean, this is there should be no holes.

1468
02:32:40.290 --> 02:32:43.709
SBU CFNS: I agree I should not be able to see a whole through this. That would be trouble. Yeah.

1469
02:32:43.810 --> 02:32:45.810
SBU CFNS: no. Also there should be no like

1470
02:32:47.290 --> 02:32:53.500
SBU CFNS: right. But but each of these blocks are not all necessarily the same size with the chances of of being accepted.

1471
02:32:53.700 --> 02:32:55.949
SBU CFNS: Get get lower as you get in the

1472
02:32:56.080 --> 02:32:59.059
SBU CFNS: No, I I think it's either you're accepted or you're not accepted

1473
02:32:59.520 --> 02:33:01.129
SBU CFNS: in these 3.

1474
02:33:01.370 --> 02:33:02.899
SBU CFNS: You're either involved.

1475
02:33:03.110 --> 02:33:04.740
SBU CFNS: but but for voxel

1476
02:33:06.000 --> 02:33:10.180
SBU CFNS: some fraction of them will hit the first jam they can scatter out in the second. J.

1477
02:33:10.630 --> 02:33:17.880
SBU CFNS: This is

1478
02:33:18.660 --> 02:33:23.030
SBU CFNS: I I I kept the the multiple scheduling it back all the time.

1479
02:33:23.490 --> 02:33:24.840
SBU CFNS: Okay, this is on.

1480
02:33:24.890 --> 02:33:31.099
SBU CFNS: I can't with. The month was carrying all the jams.

1481
02:33:31.260 --> 02:33:35.049
SBU CFNS: Yeah, that yeah, it just makes it fuzzy, but it doesn't. I mean

1482
02:33:37.260 --> 02:33:41.429
SBU CFNS: this much of the scheduling effect on the acceptance is medium.

1483
02:33:43.380 --> 02:33:44.310
But yeah.

1484
02:33:47.250 --> 02:33:47.830
okay.

1485
02:33:47.920 --> 02:33:50.119
SBU CFNS: but that's what I have.

1486
02:34:02.990 --> 02:34:03.960
SBU CFNS: Yeah, but

1487
02:34:10.920 --> 02:34:12.879
SBU CFNS: to some extent we don't really.

1488
02:34:12.920 --> 02:34:18.470
SBU CFNS: Well, those events, anyway, because they're

1489
02:34:18.640 --> 02:34:20.299
SBU CFNS: Yeah. So

1490
02:34:20.400 --> 02:34:23.070
SBU CFNS: maybe the accepting was not 100% everywhere. Okay?

1491
02:34:23.600 --> 02:34:25.579
SBU CFNS: And with the large scheduling.

1492
02:34:25.960 --> 02:34:26.970
SBU CFNS: So so

1493
02:34:28.100 --> 02:34:43.860
SBU CFNS: it's it's. It's a few events. I mean, you will. You will lose all of them if they's better, You start whether they hit the normal area or not. Doesn't matter. So so the the total acceptance is maybe not 100%, but 98%.

1494
02:34:44.010 --> 02:34:44.699
Yeah.

1495
02:34:45.230 --> 02:34:46.179
let's see.

1496
02:34:46.930 --> 02:34:51.490
SBU CFNS: Yeah, but that's not in the acceptance. I the acceptance of the targets before it makes sense.

1497
02:35:01.210 --> 02:35:04.709
SBU CFNS: there is no

1498
02:35:08.140 --> 02:35:09.409
SBU CFNS: so we should.

1499
02:35:09.570 --> 02:35:12.779
SBU CFNS: But that needs to know where the exit is.

1500
02:35:18.210 --> 02:35:20.680
SBU CFNS: Actually, it's probably the air.

1501
02:35:21.180 --> 02:35:26.909
SBU CFNS: I don't know what it did. We Did you change it to vacuum, or is it still

1502
02:35:27.100 --> 02:35:35.719
SBU CFNS: for the let the name of G 4 collect

1503
02:35:40.040 --> 02:35:46.169
SBU CFNS: you should put a in on. But just that needs to be. You need to know that.

1504
02:35:46.240 --> 02:35:47.480
SBU CFNS: So we need to know.

1505
02:35:47.930 --> 02:35:49.130
SBU CFNS: and i'll figure this.

1506
02:35:53.540 --> 02:35:56.409
SBU CFNS: and the jam material is

1507
02:35:56.530 --> 02:36:04.749
SBU CFNS: but I things together. I guess I don't know if you, if you improve it on what I try, which resembles, I don't know

1508
02:36:04.880 --> 02:36:07.449
SBU CFNS: open 5% radiation links.

1509
02:36:07.870 --> 02:36:09.220
Yeah.

1510
02:36:09.430 --> 02:36:11.809
SBU CFNS: but it's it's some standard material.

1511
02:36:12.270 --> 02:36:15.570
SBU CFNS: It's not not back to work. But are you still careful?

1512
02:36:25.550 --> 02:36:26.600
Maybe it's

1513
02:36:34.300 --> 02:36:37.290
SBU CFNS: I would really prefer if we could go to.

1514
02:36:38.850 --> 02:36:39.890
SBU CFNS: So

1515
02:36:39.970 --> 02:36:41.080
SBU CFNS: that's all.

1516
02:36:46.440 --> 02:36:47.599
and kind of said

1517
02:36:48.020 --> 02:36:50.160
SBU CFNS: yields.

1518
02:36:50.640 --> 02:36:51.800
SBU CFNS: okay.

1519
02:36:52.010 --> 02:37:02.759
SBU CFNS: I'm sure that every vacuum engine on the road would be. I think everything else is No, no no worries. it's because the

1520
02:37:02.960 --> 02:37:04.170
SBU CFNS: but not right

1521
02:37:04.240 --> 02:37:06.000
SBU CFNS: it all. Yeah.

1522
02:37:06.160 --> 02:37:07.460
SBU CFNS: And it's also pick up.

1523
02:37:08.010 --> 02:37:09.409
I didn't think so

1524
02:37:10.250 --> 02:37:11.530
in terms of radiation.

1525
02:37:11.670 --> 02:37:12.289
Yeah.

1526
02:37:20.620 --> 02:37:23.340
Alright.

1527
02:37:23.360 --> 02:37:26.360
So like

1528
02:37:28.430 --> 02:37:32.880
SBU CFNS: we have other.

1529
02:37:37.340 --> 02:37:41.620
Thank you so much.

1530
02:37:42.240 --> 02:37:43.170
SBU CFNS: Yes.

1531
02:37:43.800 --> 02:37:46.829
who's up the next? I think this is your main

1532
02:37:58.440 --> 02:38:08.100
SBU CFNS: sorry if you want to share your

1533
02:38:08.200 --> 02:38:10.069
SBU CFNS: Yes, we're all set

1534
02:38:10.230 --> 02:38:14.399
story frantzen: You can see me that it be wonderful.

1535
02:38:15.240 --> 02:38:18.749
story frantzen: be there today, and let me get my slides ready. Here.

1536
02:38:20.450 --> 02:38:23.879
let's see. So I guess this is not sharing just yet.

1537
02:38:24.430 --> 02:38:27.329
story frantzen: Oh, there we go. Okay, now I think we're about to see it

1538
02:38:29.040 --> 02:38:30.780
story frantzen: all right. This is

1539
02:38:37.300 --> 02:38:38.360
okay.

1540
02:38:38.470 --> 02:38:40.239
I'm going to simulate.

1541
02:38:40.390 --> 02:38:43.820
story frantzen: It's wonderful. Okay.

1542
02:38:44.110 --> 02:38:44.770
Okay.

1543
02:38:44.990 --> 02:38:47.130
SBU CFNS: It's the generator we're using. Yeah.

1544
02:38:47.550 --> 02:38:51.160
SBU CFNS: all right.

1545
02:38:55.570 --> 02:38:58.530
story frantzen: Okay, Hi. Everybody I

1546
02:38:58.550 --> 02:39:07.040
story frantzen: i'm here presenting on behalf of Julia, who like me, was starting on this about 3 months ago now, so she and I have been

1547
02:39:07.200 --> 02:39:18.070
story frantzen: racing to make sense of what you guys have been probably working on for a lot longer. So, anyway. we have been spending the last 3 months mainly trying to

1548
02:39:18.540 --> 02:39:19.699
story frantzen: corroborate

1549
02:39:19.820 --> 02:39:29.189
story frantzen: a lot of the background rates and event rates that Jon had, I think, calculated either by hand or some black box methods.

1550
02:39:29.440 --> 02:39:42.709
story frantzen: and we have been so. So the way our simulations are set up right now. We have the minds generator that is able to simulate our Qed background, which we're also using as our signal, just with a different scaling

1551
02:39:42.870 --> 02:39:56.669
story frantzen: in theory. We would also have the minds generators simulating a single positrons. that is proving to be a little bit challenging. I'll get to that. And we're using the Olympics generator for the radiated electrons. Slow down to create.

1552
02:39:56.710 --> 02:39:57.340
Yeah.

1553
02:39:57.530 --> 02:39:59.639
the reducible background with

1554
02:40:02.950 --> 02:40:03.760
So

1555
02:40:05.980 --> 02:40:07.000
story frantzen: so.

1556
02:40:07.090 --> 02:40:15.469
story frantzen: we've mostly been able in the last few months, despite a lot of setbacks with debugging our own code, we've mostly been able to get a pretty

1557
02:40:15.610 --> 02:40:23.259
story frantzen: a rough read on what Jon's numbers were for a lot of these rates, you see at the bottom of this panel everything in yellow was something that yawn reported

1558
02:40:23.520 --> 02:40:25.990
story frantzen: and then the column to that

1559
02:40:26.090 --> 02:40:33.690
story frantzen: to the left of that respective yellow block as well. We're getting for that. Things that are empty are just values that we

1560
02:40:33.720 --> 02:40:36.739
story frantzen: calculate and simulation side, but beyond it. Not

1561
02:40:36.840 --> 02:40:41.240
story frantzen: so. We're seeing some pretty good agreement with the Qed background.

1562
02:40:41.360 --> 02:40:43.240
and signal

1563
02:40:43.560 --> 02:40:53.129
story frantzen: But as you can probably see, the Tr. And simulations differ quite a bit especially at higher a prime mats and beam energy for the positron rate.

1564
02:40:55.020 --> 02:40:56.639
story frantzen: And

1565
02:40:57.390 --> 02:41:04.760
story frantzen: electron rates, the single electron rates at the far right are pretty good agreement also. This table, by the way, our values are

1566
02:41:04.900 --> 02:41:09.000
story frantzen: much smaller statistics than yawns for this. So.

1567
02:41:09.240 --> 02:41:15.720
story frantzen: having at least an order of magnitude. Similarity is is pretty good, as far as our data shows right now.

1568
02:41:16.190 --> 02:41:18.369
story frantzen: So our code is mostly working

1569
02:41:18.460 --> 02:41:26.689
story frantzen: the discrepancy with the potatrons. we have been spending quite a bit of time trying to decipher. It boils down to

1570
02:41:27.020 --> 02:41:36.809
story frantzen: these 2 lines in the lines generator code, because the minds generator was not, I think, intended to be a generator for a single particle.

1571
02:41:38.560 --> 02:41:43.169
story frantzen: we think we are slightly misunderstanding the

1572
02:41:43.440 --> 02:41:44.020
the

1573
02:41:44.300 --> 02:41:48.810
story frantzen: variables in source code for the Qed

1574
02:41:49.680 --> 02:41:51.190
story frantzen: cross-section computation.

1575
02:41:51.330 --> 02:42:10.199
story frantzen: and what you're seeing. These yellow boxes is quite literally what we've actually been debating for a good week or 2. Now. the code E, 2 E. One. These are one of them is a positron. One of them is an electron. it defines this intermediate reference frame that gets Lorentz boosted

1576
02:42:10.210 --> 02:42:14.449
story frantzen: back to the lab frame. It should be pretty easy to find out which is which.

1577
02:42:14.570 --> 02:42:17.579
story frantzen: surprisingly, it is not proven to be.

1578
02:42:17.840 --> 02:42:19.400
story frantzen: And

1579
02:42:19.520 --> 02:42:21.010
story frantzen: we have

1580
02:42:21.080 --> 02:42:26.009
SBU CFNS: let's see on this next slide.

1581
02:42:26.150 --> 02:42:29.730
SBU CFNS: If this is an active discussion in the simulation group.

1582
02:42:29.790 --> 02:42:37.549
SBU CFNS: I should note that I have an obsessively annotated version of this that I use for a different analysis. That was an absolute.

1583
02:42:37.690 --> 02:42:44.079
SBU CFNS: It was different project, but because it was not working well. I have annotated the hell out of my copy.

1584
02:42:44.130 --> 02:42:45.910
SBU CFNS: the my generator

1585
02:42:46.040 --> 02:42:49.119
SBU CFNS: modified to do TV scale scattering.

1586
02:42:49.410 --> 02:43:05.580
SBU CFNS: and that might be a useful comparison. It's like it's been a little while since I've opened it up, but I I i'm pretty sure like every line is like this is what this line does because of this game really infuriated. And you're right, it is. It's annoyingly hard to figure out exactly what you're doing here.

1587
02:43:06.260 --> 02:43:16.079
SBU CFNS: Yeah, that's extremely useful. Yeah, I tell you that we have an annotate that's now been annotated by changing the gene and Star and Julian, but it's still.

1588
02:43:16.190 --> 02:43:22.749
SBU CFNS: I think quite a bit less. So we haven't gone through all the

1589
02:43:23.500 --> 02:43:26.550
SBU CFNS: Okay. Did you look into a. Q. And a background?

1590
02:43:26.650 --> 02:43:32.740
SBU CFNS: Yes.

1591
02:43:32.890 --> 02:43:35.080
SBU CFNS: that that that's also the poring?

1592
02:43:38.560 --> 02:43:47.249
story frantzen: Yeah, this should be an easy fix, frankly, but yes, an annotated a more annotated version of the

1593
02:43:47.730 --> 02:43:49.520
SBU CFNS: Independently.

1594
02:43:50.660 --> 02:44:07.159
story frantzen: Yes, to end up. Yeah, but yes, Well, well, at any rate, what we've been kind of seeing as the difference between again these 2 lines of code, one where we have 2, as our particle, we've swapped that for e one trying to get yawns. No. E rates, or

1595
02:44:07.930 --> 02:44:12.270
story frantzen: only the posix on only rates. So the top row that you're seeing on the screen.

1596
02:44:12.400 --> 02:44:18.720
story frantzen: we call this the the pre swap configuration. This is the default source code for bunch of and

1597
02:44:18.970 --> 02:44:30.789
story frantzen: well, this actually shows it yield the sensitivity on the top left. It's pretty well in accordance with our intuition, because we're seeing again a far spread angle on the electron spectrometer away from the beam line.

1598
02:44:31.020 --> 02:44:37.620
story frantzen: that's where our sensitivity should be maximized, because the reducible background is minimal.

1599
02:44:37.700 --> 02:44:42.019
story frantzen: There. Of course, the reducible background we expect to pick up closer to the beam line

1600
02:44:42.060 --> 02:44:44.970
because of stray electrons just entering the spectrometer. So

1601
02:44:45.970 --> 02:44:53.270
story frantzen: the the second column you're seeing these reduceable rates from top to bottom. This seems to be kind of what the

1602
02:44:53.290 --> 02:44:56.790
story frantzen: the effect of swapping those 2 particles in the generator

1603
02:44:57.030 --> 02:44:59.700
story frantzen: most effects.

1604
02:44:59.980 --> 02:45:04.830
story frantzen: You see that swapping it greatly reduces the reducible background

1605
02:45:04.930 --> 02:45:11.630
story frantzen: in such a way that the sensitivity is actually biased away from that top left region more central.

1606
02:45:12.980 --> 02:45:16.149
story frantzen: which isn't quite in accordance with our intuition. So

1607
02:45:16.170 --> 02:45:17.289
SBU CFNS: if I

1608
02:45:17.340 --> 02:45:22.739
SBU CFNS: Okay, well, I'm thinking of it. I'm sorry to interrupt Can you go back to the video slide for a second.

1609
02:45:23.980 --> 02:45:28.419
SBU CFNS: if I remember correctly, Theta D. And 5 D

1610
02:45:28.540 --> 02:45:31.620
SBU CFNS: are used in community background

1611
02:45:31.760 --> 02:45:35.099
SBU CFNS: also in a way that assumes they are the electron.

1612
02:45:35.660 --> 02:45:38.319
SBU CFNS: So because it it does some, some

1613
02:45:38.690 --> 02:45:45.369
story frantzen: it's now the

1614
02:45:45.490 --> 02:45:51.540
SBU CFNS: so if you do.

1615
02:45:51.640 --> 02:46:00.939
SBU CFNS: But but if you swap them but you still these beta d and 5 d in those arguments. It will not behave correctly, because it will try to do the symmetry

1616
02:46:01.500 --> 02:46:04.479
SBU CFNS: trying to be electron

1617
02:46:06.620 --> 02:46:09.520
SBU CFNS: foster where you saw the 2 electrons in the Federal State.

1618
02:46:10.020 --> 02:46:14.119
SBU CFNS: They'll try to do that, but one of them will be a positive one. So what we actually look like same basics

1619
02:46:14.230 --> 02:46:18.210
wait but like, but like this, we're

1620
02:46:18.260 --> 02:46:24.890
SBU CFNS: But but the point is, you know. So these these generating and d for the positron, and and trying to

1621
02:46:24.930 --> 02:46:41.339
SBU CFNS: try to generate these things and say, that's an try to generate them and say, that's the electron is a distinctly different thing. Yeah, because these arguments feed it in as if it is yeah, that's the one which is why we the original version.

1622
02:46:41.470 --> 02:46:42.350
So I

1623
02:46:42.430 --> 02:46:49.060
SBU CFNS: do. You think that's better? And so the original version? I thought I saw someone recognize that if I change the

1624
02:46:49.180 --> 02:46:56.640
SBU CFNS: the positron angle in the setup file it's ploted as the change in the electron angle in this.

1625
02:46:57.540 --> 02:46:59.250
SBU CFNS: Yes. Oh, wait.

1626
02:47:00.580 --> 02:47:10.830
SBU CFNS: Is that a different thing? Okay. So we also have it's actually electronic device just tracking.

1627
02:47:10.940 --> 02:47:22.149
SBU CFNS: But that's that's the only thing I change. I think if you change this in a way, that for me e 2 is the electron in the end.

1628
02:47:22.560 --> 02:47:23.270
SBU CFNS: Oh.

1629
02:47:23.680 --> 02:47:24.530
SBU CFNS: right.

1630
02:47:25.390 --> 02:47:35.249
SBU CFNS: I left this cycle name, but I change the definition of what the electron and positron is which you want to be.

1631
02:47:36.030 --> 02:47:42.019
SBU CFNS: No, I I think in the end it doesn't matter.

1632
02:47:42.230 --> 02:47:43.950
SBU CFNS: It just has to be consistent.

1633
02:47:44.900 --> 02:48:02.319
SBU CFNS: Yes, but but in this, once in it's you can be because you pass it both for vectors that correspond to to either, and then angles. No, I I mean you pass an E hours, which is the electron out, because that's it. But it has a queue out as well.

1634
02:48:18.610 --> 02:48:23.690
SBU CFNS: and if it's the posit trial. Then you've flipped it. That's fine unless you flip it elsewhere.

1635
02:48:24.490 --> 02:48:38.359
SBU CFNS: This is where it's. Okay, so. But let's let's sit down with the next, you know, tomorrow, or whatever i'll crack out. My! No, I understand. I I try both, and pick the not your number.

1636
02:48:38.690 --> 02:48:47.050
story frantzen: Well, yes, so to that point, so to that point about choosing the more conservative value we were finding. that

1637
02:48:47.230 --> 02:49:02.650
story frantzen: that's swap. So. The second yellow rectangle we see at the far right of the screen. we're finding that it's a more conservative. It's a more conservative value when you swap, but only in certain regions, as you can see, there's actually a huge drop off in the noe rates

1638
02:49:02.660 --> 02:49:07.670
story frantzen: in that kind of sensitivity maximizing that.

1639
02:49:07.690 --> 02:49:21.149
story frantzen: So it was increasing slightly, though, and I was starting to get optimistic. that. I was getting your rates on. but that was more for smaller positron angles and higher electron angles where there actually occasionally is

1640
02:49:21.180 --> 02:49:23.410
an increase in that we right there.

1641
02:49:24.780 --> 02:49:25.490
story frantzen: But

1642
02:49:25.530 --> 02:49:35.970
story frantzen: anyway, we're we're mostly convinced just at least by our intuition. For now, anyway, that the top row is is at least more

1643
02:49:36.620 --> 02:49:41.149
story frantzen: sensible, but we're still sorting through it. So what we did, just as a as

1644
02:49:41.930 --> 02:49:45.979
story frantzen: just as a test measure to test our own code that we've been working through.

1645
02:49:46.800 --> 02:49:52.149
story frantzen: We use the assumption here in the top row that first. So that was the default

1646
02:49:52.290 --> 02:49:53.840
e to out

1647
02:49:53.990 --> 02:50:03.000
version of this to produce some some of these twod sensitivity plots for given configurations that we're interested in

1648
02:50:03.370 --> 02:50:04.199
story frantzen: testing.

1649
02:50:05.440 --> 02:50:08.940
It's hard to maybe see all these scales and angles. But

1650
02:50:11.360 --> 02:50:15.159
this is what we have for the again default minds code.

1651
02:50:18.510 --> 02:50:19.090
So

1652
02:50:20.840 --> 02:50:22.810
SBU CFNS: I think it's already.

1653
02:50:22.910 --> 02:50:29.119
SBU CFNS: You may have turned it out a little bit.

1654
02:50:29.690 --> 02:50:32.720
story frantzen: Oh, sorry. Okay.

1655
02:50:33.440 --> 02:50:49.520
story frantzen: yeah. So in in case it wasn't clear these plus you're seeing now on the screen, are ones we've made assuming the default lines code where we were using that to out the posit front to define that angle instead of the electron,

1656
02:50:49.890 --> 02:50:59.080
story frantzen: only because it was giving at the time more sensible and consistent, since it is that we're seeing now on the screen for the configurations. It sounds like we're interested in.

1657
02:51:00.450 --> 02:51:03.930
story frantzen: so that first number is the mass. P. A prime second number is

1658
02:51:04.920 --> 02:51:05.820
the beam string.

1659
02:51:07.560 --> 02:51:10.729
story frantzen: I don't know if these pictures are too small to see these scales, but

1660
02:51:10.750 --> 02:51:13.440
story frantzen: because they're all kind of the same shape some sense, but

1661
02:51:14.780 --> 02:51:16.560
story frantzen: not much that shouldn't

1662
02:51:16.920 --> 02:51:18.940
we expected, I think, looking.

1663
02:51:24.090 --> 02:51:27.160
story frantzen: Yes, so okay. So we have that what else we have.

1664
02:51:27.340 --> 02:51:36.879
story frantzen: So Julia was looking also at the dependence of the sensitivity on other parameters

1665
02:51:37.360 --> 02:51:41.720
story frantzen: current. So I think right now we've been running our simulations at about

1666
02:51:41.900 --> 02:51:47.859
story frantzen: 1.5 times. This is 0 point. 1 5

1667
02:51:47.890 --> 02:51:49.460
we have.

1668
02:51:52.010 --> 02:51:53.529
story frantzen: Yeah, yes, thank you.

1669
02:51:54.120 --> 02:52:01.839
story frantzen: but yeah. So it looks like, the sensitivity picks up sort of as a function of current.

1670
02:52:02.220 --> 02:52:07.220
story frantzen: down with the cavity, and then on the other plot. We have just a dependence on the energy.

1671
02:52:07.260 --> 02:52:13.699
story frantzen: we're more confident, the one on the left and the right. We're working on both of these. Still, because their code can be

1672
02:52:14.920 --> 02:52:20.539
SBU CFNS: Yeah, I I I don't quite believe the 32 point. I I don't think there is a reason why it should get worse again.

1673
02:52:20.850 --> 02:52:35.610
SBU CFNS: I agree there. Was it what we wanted to check there was? If we weren't, we optimizing some energy we had essentially. Just think to the angles that were best at the 30, and i'm not sure whether Julie was suggesting

1674
02:52:36.030 --> 02:52:42.790
SBU CFNS: you mentioned for leading everything 6 to 30, and then we turned up to the

1675
02:52:43.700 --> 02:52:52.990
SBU CFNS: I'm. Julia, are you using single

1676
02:52:53.800 --> 02:52:55.900
Julia Azzi: sorry? Can you repeat what you just said.

1677
02:52:55.980 --> 02:53:14.330
SBU CFNS: Yeah, you know the right-hand clock here? I know we left the angles at what looked like good values at 30 the the central momentum where we re-optimizing 9 of those angles. Everything is but as we try to re-optimizing it based on like the entire bachelor.

1678
02:53:14.700 --> 02:53:17.879
SBU CFNS: But but the optimal angle

1679
02:53:18.280 --> 02:53:21.439
SBU CFNS: so so you can keep one angle fixed, but the other angle is

1680
02:53:21.460 --> 02:53:28.259
SBU CFNS: has to change, though. Well, our point is, if we build it and we build it for the best and 130 of the management.

1681
02:53:28.390 --> 02:53:32.750
SBU CFNS: Okay.

1682
02:53:33.320 --> 02:53:41.009
SBU CFNS: Okay, yeah, that's a different question. Okay.

1683
02:53:44.800 --> 02:53:46.130
All good.

1684
02:53:46.170 --> 02:53:49.119
SBU CFNS: Okay. I can see that. Then, if you go to files.

1685
02:53:54.600 --> 02:54:04.429
SBU CFNS: But I mean the sensitivities are all very close together.

1686
02:54:04.910 --> 02:54:11.899
SBU CFNS: And yeah, the left hand was based on the knowledge that we've optimized everything from 150 by from us. But if you look at as much happier running than 300.

1687
02:54:13.550 --> 02:54:16.369
What's that going to affect us? At least in this sense?

1688
02:54:20.780 --> 02:54:22.510
SBU CFNS: Sorry. Sorry.

1689
02:54:23.110 --> 02:54:27.400
story frantzen: All good. yeah, no. And beyond these plots we

1690
02:54:27.430 --> 02:54:29.119
story frantzen: have been trying

1691
02:54:29.150 --> 02:54:36.640
story frantzen: Also, I guess this is tantamount to confirming the sensitivities of the Tdr. But we are still working to verify the

1692
02:54:37.160 --> 02:54:38.939
exclusions as well.

1693
02:54:39.160 --> 02:54:47.400
story frantzen: Our code was a little finicky. Thankfully Julia helped spot some some but

1694
02:54:47.610 --> 02:54:53.130
story frantzen: right now we obtain these curves. I think our biggest limitation of these curves right now is again the

1695
02:54:53.220 --> 02:54:55.970
story frantzen: positron rate ambiguates, because

1696
02:54:56.020 --> 02:54:59.199
up to about a 20% difference in those rates between

1697
02:54:59.240 --> 02:55:03.880
those 2 configure iterations of the launch generator. has a big effect.

1698
02:55:04.090 --> 02:55:05.139
these exclusions.

1699
02:55:09.180 --> 02:55:10.190
But

1700
02:55:12.210 --> 02:55:13.229
let's see.

1701
02:55:13.390 --> 02:55:16.040
story frantzen: Oh, yes, and then we're also hoping once we

1702
02:55:16.180 --> 02:55:28.439
get these exclusions consist of the Tdr we're also hoping to implement Jen's d acceptance somehow into our simulations.

1703
02:55:28.590 --> 02:55:30.699
to try and be more precise.

1704
02:55:31.510 --> 02:55:32.100
I want

1705
02:55:34.830 --> 02:55:45.949
story frantzen: other than that. I think that's about all this stuff we had to show. Anyway, our checklist now is again a lot of it right now is trying to figure out just how the minds generator is really doing things validating

1706
02:55:45.990 --> 02:55:47.830
story frantzen: the positron rates in specific

1707
02:55:48.480 --> 02:55:53.869
That functionality of being more precise about the spectrometer sentences we have given.

1708
02:55:55.790 --> 02:56:02.940
story frantzen: and hopefully very soon, finally having some pretty reliable sensitivity.

1709
02:56:03.540 --> 02:56:09.160
SBU CFNS: So I one more question so, for the sensitivities. You need to know the resolution, right?

1710
02:56:09.320 --> 02:56:12.940
SBU CFNS: So how large? What area are you integrating?

1711
02:56:19.260 --> 02:56:20.119
SBU CFNS: Wanna: Hop.

1712
02:56:22.250 --> 02:56:26.589
SBU CFNS: Okay, yeah. There there is an optimum somewhere depending on the trade.

1713
02:56:27.290 --> 02:56:34.690
SBU CFNS: Okay, yeah. So so it probably is a little bit worse. Now, this 146

1714
02:56:36.090 --> 02:56:49.449
SBU CFNS: I think first we want to be.

1715
02:56:49.610 --> 02:56:50.869
But there at least

1716
02:56:50.940 --> 02:56:52.559
more likely to be right.

1717
02:57:05.710 --> 02:57:11.219
SBU CFNS: I mean it, and the I mean, we tried to with Metrop and this metrop.

1718
02:57:11.450 --> 02:57:13.190
SBU CFNS: We they also in the

1719
02:57:13.290 --> 02:57:17.639
Okay. So that is also

1720
02:57:18.080 --> 02:57:22.940
SBU CFNS: I I would not look into that net prop again.

1721
02:57:22.970 --> 02:57:28.359
SBU CFNS: Yeah. So this is

1722
02:57:28.630 --> 02:57:32.009
SBU CFNS: which period is using it. We should be able to get.

1723
02:57:32.060 --> 02:57:40.810
I am aware of several

1724
02:57:40.930 --> 02:57:41.890
that

1725
02:57:45.830 --> 02:57:48.029
SBU CFNS: I think you're

1726
02:57:48.500 --> 02:57:59.710
SBU CFNS: okay.

1727
02:57:59.890 --> 02:58:10.079
SBU CFNS: You know how it is right. It takes it. It's more time to validate something than you've been in the first place. So it's actually really great, having both Julia and i'm sorry working on this because it's enabled

1728
02:58:10.120 --> 02:58:16.059
SBU CFNS: do something in their own way, and they get.

1729
02:58:16.890 --> 02:58:25.969
SBU CFNS: But there's 2 things that still that kind of monthly. So we're

1730
02:58:26.330 --> 02:58:29.630
we are

1731
02:58:30.770 --> 02:58:35.930
there's always

1732
02:58:36.190 --> 02:58:41.000
SBU CFNS: I, I I If you, if you can go back and go to the

1733
02:58:41.440 --> 02:58:43.530
SBU CFNS: electron single rates.

1734
02:58:44.620 --> 02:58:56.969
SBU CFNS: I think that looks that. That was one question. We had right. That's that's not right. That's what I expect.

1735
02:58:56.990 --> 02:59:03.960
story frantzen: What i'm into now is that you go to there's actually

1736
02:59:04.320 --> 02:59:12.170
some of the things one is. These read inputs: all look very similar to be giving them such a different sensitivity.

1737
02:59:12.200 --> 02:59:13.239
You can kind of understand.

1738
02:59:16.940 --> 02:59:20.909
but then, the next thing, if you go to the next slide.

1739
02:59:29.640 --> 02:59:32.229
SBU CFNS: so I think that that's probably just a little.

1740
02:59:32.390 --> 02:59:32.960
That's easy.

1741
02:59:33.170 --> 02:59:37.430
SBU CFNS: I'm curious. What's what's carving a whole out of the 1,731

1742
02:59:37.720 --> 02:59:41.629
SBU CFNS: that that here. Looks like statistics.

1743
02:59:41.920 --> 02:59:48.079
SBU CFNS: Yeah, yes, and it's some of that streaking. But like with the back of the main band as the

1744
02:59:48.460 --> 02:59:51.439
SBU CFNS: the sharp cut off.

1745
02:59:52.190 --> 02:59:55.650
It's like a difference between point 3. My.

1746
02:59:55.700 --> 03:00:15.249
SBU CFNS: but I see what you need.

1747
03:00:16.150 --> 03:00:20.729
SBU CFNS: I if you have kicked and symmetrically that is the sensitivity.

1748
03:00:20.900 --> 03:00:24.680
SBU CFNS: so that that's where you'd expect the most interesting stuff. That's very

1749
03:00:26.390 --> 03:00:35.639
SBU CFNS: so. I i'm not. That's I really like to see. So so you see that this is high, and then it gets more, and then it's how you get.

1750
03:00:35.700 --> 03:00:42.329
SBU CFNS: because that means that the initial state radiation works as it's because that's that means

1751
03:00:42.450 --> 03:00:52.939
SBU CFNS: probably a low acceptance, and that's a high moment of my sentence in the other form. So here you see, close to the to the recipes you see close to the

1752
03:00:53.290 --> 03:00:54.530
SBU CFNS: to the 0. P:

1753
03:00:54.570 --> 03:00:55.270
That's pretty cool.

1754
03:00:57.600 --> 03:01:01.599
Yeah. So

1755
03:01:02.570 --> 03:01:04.630
SBU CFNS: because I have not called any of this

1756
03:01:04.660 --> 03:01:09.020
SBU CFNS: what's the

1757
03:01:09.670 --> 03:01:21.269
SBU CFNS: Yes. So we, I believe our conclusion from stories that you need to.

1758
03:01:22.150 --> 03:01:36.229
SBU CFNS: That is not being the fault you see on the bottom left here. But it's no no, it must give us time. I mean we're we're still working on.

1759
03:01:36.650 --> 03:01:39.660
SBU CFNS: I can probably not tonight, but

1760
03:01:39.700 --> 03:01:46.950
SBU CFNS: in theory I can try to reproduce these I' to do is add in a weird to to get back to the Collider frames, but money does back to the fixed.

1761
03:01:47.160 --> 03:01:47.910
SBU CFNS: Oh.

1762
03:01:48.110 --> 03:01:56.560
SBU CFNS: it sounds it's going to be in free lines with anyone's good.

1763
03:01:58.970 --> 03:02:02.470
SBU CFNS: but he said, I think we should publish it again.

1764
03:02:11.300 --> 03:02:18.080
SBU CFNS: I it, my.

1765
03:02:18.340 --> 03:02:23.110
SBU CFNS: if you check that in some.

1766
03:02:23.450 --> 03:02:26.099
SBU CFNS: and it would be that we just

1767
03:02:26.300 --> 03:02:33.109
SBU CFNS: It's a you all the way around by changing the documentation. So you know, yeah, this is the

1768
03:02:34.820 --> 03:02:37.990
SBU CFNS: well. This needs to be done and sounds terrible to you. But Yes.

1769
03:02:48.070 --> 03:02:49.049
it's easier.

1770
03:02:54.750 --> 03:02:55.570
Everybody.

1771
03:03:33.310 --> 03:03:37.449
we can test that next.

1772
03:03:37.670 --> 03:03:40.169
SBU CFNS: So for this

1773
03:03:40.830 --> 03:03:44.669
SBU CFNS: and and the

1774
03:03:44.790 --> 03:03:56.399
SBU CFNS: in this study is given by.

1775
03:03:56.760 --> 03:04:06.489
so we haven't.

1776
03:04:06.690 --> 03:04:11.369
changing these and making it possible.

1777
03:04:11.400 --> 03:04:13.330
or we could just basically

1778
03:04:14.060 --> 03:04:25.300
SBU CFNS: put in the

1779
03:04:25.400 --> 03:04:27.809
and then you can put it in the

1780
03:04:35.790 --> 03:04:38.220
And that

1781
03:04:42.260 --> 03:04:43.970
SBU CFNS: are the other questions for story.

1782
03:04:46.090 --> 03:04:47.180
Don't think so.

1783
03:04:47.610 --> 03:04:49.670
So it should probably

1784
03:04:51.290 --> 03:04:57.110
SBU CFNS: sorry. Send me the slides, please. I'll post them.

1785
03:04:58.040 --> 03:05:01.020
story frantzen: Yes, of course. Okay.

1786
03:05:01.980 --> 03:05:04.300
SBU CFNS: And

1787
03:05:05.100 --> 03:05:05.680
okay.

1788
03:05:06.060 --> 03:05:11.999
SBU CFNS: so we have 10 min into the so.

1789
03:05:14.800 --> 03:05:16.620
Not any.

1790
03:05:21.730 --> 03:05:24.630
SBU CFNS: I I I know you.

1791
03:05:25.220 --> 03:05:28.550
SBU CFNS: yeah. So if you let's watch your topic, that works

1792
03:05:28.880 --> 03:05:35.569
Aveen Mahon: Yeah, sounds good. Mine shouldn't really take that long. In any case a lot of it is is things that you guys have probably seen before.

1793
03:05:35.870 --> 03:05:38.129
Aveen Mahon: but with just a few updates. So

1794
03:05:38.520 --> 03:05:41.420
Aveen Mahon: let's see here. If I can get this in

1795
03:05:42.110 --> 03:05:43.320
Aveen Mahon: the screenload.

1796
03:05:43.450 --> 03:05:44.719
Aveen Mahon: Can you guys see that?

1797
03:05:44.950 --> 03:05:47.680
Aveen Mahon: And it's in presentation Node: yeah.

1798
03:05:48.090 --> 03:05:51.699
Aveen Mahon: Okay. So yeah, i'm just gonna give you guys a

1799
03:05:51.790 --> 03:05:54.350
Aveen Mahon: little update on the status of the Elinac

1800
03:05:54.430 --> 03:05:56.990
Aveen Mahon: at aerial and the beam optics model.

1801
03:05:57.660 --> 03:05:58.830
Aveen Mahon: So

1802
03:06:01.220 --> 03:06:07.170
Aveen Mahon: yeah, so this is just you know, overview of triumph for those who may not have been. We have

1803
03:06:07.240 --> 03:06:11.040
Aveen Mahon: the aerial building over here. The is I call

1804
03:06:11.470 --> 03:06:14.109
Aveen Mahon: one and 2 over here, which we don't really

1805
03:06:14.210 --> 03:06:19.070
Aveen Mahon: particularly mind right now and then the Mezzon Hall over here, in which we have

1806
03:06:21.120 --> 03:06:25.960
Aveen Mahon: cyclotron, which is the main driver of most of triumph facilities. Right. Now.

1807
03:06:25.980 --> 03:06:30.369
Aveen Mahon: Isaac, where you do a lot of the post-processing of radioactive isotopes

1808
03:06:30.630 --> 03:06:35.609
Aveen Mahon: and then aerial, which is where we're going to continue to do some of those Isotope

1809
03:06:35.730 --> 03:06:37.749
Aveen Mahon: productions with additional targets.

1810
03:06:37.820 --> 03:06:56.439
Aveen Mahon: And in order to do that, we also built the Elinac in the electron hall. And this is a super conducting electron Linux which is main goal, is to be the second driver beam for aerial. But that's only going to be online in 2,025. So in the meantime we have experiments like you, taking advantage of the facility.

1811
03:06:56.640 --> 03:07:04.009
Aveen Mahon: So I just included some details on Ariel because you guys included it in the title. If if you're interested.

1812
03:07:04.510 --> 03:07:09.230
Aveen Mahon: just gonna add to to target stations to our current re is to production

1813
03:07:09.560 --> 03:07:17.969
Aveen Mahon: one that's driven by a proton being from the cyclotron and one that's driven by an electron being from the eeleneck. So these are just the is someone trying to say something.

1814
03:07:18.960 --> 03:07:19.740
SBU CFNS: No.

1815
03:07:19.870 --> 03:07:21.839
Aveen Mahon: okay. I kept hearing like a like a

1816
03:07:22.110 --> 03:07:23.630
Aveen Mahon: background noise there. Sorry.

1817
03:07:23.810 --> 03:07:27.019
Aveen Mahon: But yeah. So these are the different

1818
03:07:27.110 --> 03:07:30.139
Aveen Mahon: outlines of the isotopes that will be produced there.

1819
03:07:33.290 --> 03:07:36.700
Aveen Mahon: and the current status of that is that this is an

1820
03:07:36.960 --> 03:07:48.750
Aveen Mahon: kind of cross-section view of the target hall where we have the electron target and the proton target ae, t and aptw, and those have recently had concrete port into them. So

1821
03:07:49.070 --> 03:07:56.299
Aveen Mahon: there isn't the the connection to the driver. Beam tunnel is not yet complete, but a lot of the target stations are moving

1822
03:07:56.620 --> 03:08:01.659
Aveen Mahon: quite well along towards completion. So that's where the status of aerial is at right now.

1823
03:08:02.230 --> 03:08:06.880
Aveen Mahon: on to what we're a bit more interested in, which is the this is

1824
03:08:07.440 --> 03:08:13.139
Aveen Mahon: a picture in the E Hall of the machine that we are. I've been talking about

1825
03:08:13.200 --> 03:08:28.439
Aveen Mahon: most of the day, so from right to left we have the Egan, which is where the beam is produced at 300 kilovolts. Here we have the in which is the injector cryo module that takes it up to 10 mega mega electron volts.

1826
03:08:28.760 --> 03:08:40.770
Aveen Mahon: maybe, and then we continue down to the aca or accelerator crime module that takes up to 30 Mev. And around a corner to a dump, so i'll just have I have some pictures of these in a bit more detail here.

1827
03:08:41.550 --> 03:08:45.610
Aveen Mahon: and this is a depiction of what we just saw with the same layout

1828
03:08:45.650 --> 03:08:56.509
Aveen Mahon: Egan in Jac. Htt: and right now we have total beam energy of 30. Mev. Max beam current, 10 milli amps, and a couple of other of the

1829
03:08:56.640 --> 03:08:59.200
Aveen Mahon: machine parameters that we have right now.

1830
03:08:59.350 --> 03:09:04.350
Aveen Mahon: and of course, with the high energy beam jump having a Max Power rating of 10 kilowatts.

1831
03:09:07.240 --> 03:09:10.599
Aveen Mahon: yeah, none of this is is like particularly

1832
03:09:13.220 --> 03:09:16.399
Aveen Mahon: useful for darkly this is just if you guys are curious about.

1833
03:09:16.700 --> 03:09:20.539
Aveen Mahon: you know, different of the components. This is the electron going to cross-section of that

1834
03:09:20.650 --> 03:09:24.529
Aveen Mahon: where we have it contained within a vessel that has sf 6 in it

1835
03:09:24.660 --> 03:09:25.740
Aveen Mahon: pressurized

1836
03:09:26.560 --> 03:09:28.280
Aveen Mahon: and cathode anode

1837
03:09:28.660 --> 03:09:36.220
Aveen Mahon: and a Rf. Tuner this generates the 300 Kv punches at our frequency of 650 megahertz.

1838
03:09:38.910 --> 03:09:45.839
Aveen Mahon: Then we have the injector cavity, which is 1 9 cell cavity of super conducting Niobium

1839
03:09:46.240 --> 03:09:48.879
Aveen Mahon: with our frequency of 1.3 gigahertz

1840
03:09:49.290 --> 03:09:53.100
Aveen Mahon: that's operated at 2 kelvin so nice and cold.

1841
03:09:53.740 --> 03:10:02.129
Aveen Mahon: and then the accelerator cavity is similar except it's just 2 of these 9 cell cavities in a row, so it's it's twice as long.

1842
03:10:03.830 --> 03:10:11.709
Aveen Mahon: and then this is the area that we're most interested in which is the high power dump. So if you're looking at this picture here.

1843
03:10:12.140 --> 03:10:26.689
Aveen Mahon: if you can see my mouse for these 2 green boxes are, there's actually a branch in the beam line, one of which leads off down this dark tunnel towards where aerial will be. But until that's complete right now, it. We just send the beam off to the left, around into this dump.

1844
03:10:26.800 --> 03:10:28.379
Aveen Mahon: which is our tuning dump.

1845
03:10:28.680 --> 03:10:31.969
Aveen Mahon: and we're going to take advantage of the space between this blue

1846
03:10:32.440 --> 03:10:35.050
Aveen Mahon: bending magnet, which is the end of this bend

1847
03:10:35.640 --> 03:10:39.060
Aveen Mahon: until the beginning of this shielding to install the darklight experiment.

1848
03:10:40.770 --> 03:10:41.570
Aveen Mahon: So

1849
03:10:41.740 --> 03:10:46.110
Aveen Mahon: yeah, current status of the Elonac is that we have commissioned it up to 30 Mev.

1850
03:10:46.260 --> 03:10:48.109
Aveen Mahon: At to power of 10 kilowatt.

1851
03:10:48.350 --> 03:10:50.549
Aveen Mahon: and we've done a lot of

1852
03:10:50.670 --> 03:10:57.559
Aveen Mahon: made a lot of progress even since the last collaboration meeting on just tracking various issues and fixing those.

1853
03:10:57.690 --> 03:10:58.830
Aveen Mahon: So

1854
03:10:59.840 --> 03:11:17.719
Aveen Mahon: we've had at least 10 issues resolved since last meeting, which I believe was in May. So we've upgraded certain beam line components, updated control systems, etc. But we're still tracking around 15 plus to improve the overall performance and reliability of the machine. And one of the things that we're aiming on doing very soon

1855
03:11:17.730 --> 03:11:27.229
Aveen Mahon: is we're gonna eat this hopefully by the end of the year. But we may not end up having time with people going on vacation for the holidays, but we intend to do helium conditioning

1856
03:11:27.390 --> 03:11:28.990
Aveen Mahon: of the

1857
03:11:29.120 --> 03:11:42.260
Aveen Mahon: the crime modules and cavities by the end of 2,022 early 2,023. So helium conditioning is a technique that's used to try to mitigate the field emission. That is that takes place inside these cavities.

1858
03:11:42.340 --> 03:11:44.020
Aveen Mahon: so it should reduce

1859
03:11:44.040 --> 03:11:51.320
Aveen Mahon: field, a mission which will in turn reduce the the background. X-rays and all of that that's produced by the cavity so that would be good for your guys

1860
03:11:51.350 --> 03:11:56.629
Aveen Mahon: background. So I felt that that was probably the most important thing to highlight in terms of what we are

1861
03:11:56.880 --> 03:11:57.970
Aveen Mahon: working on

1862
03:11:58.440 --> 03:12:00.480
Aveen Mahon: at in terms of the

1863
03:12:00.600 --> 03:12:02.210
Aveen Mahon: issues

1864
03:12:02.660 --> 03:12:03.770
Aveen Mahon: issue tracking.

1865
03:12:03.910 --> 03:12:10.720
Aveen Mahon: So now on to Well, does anyone have any questions about the the status before I move on to the Beam Optics

1866
03:12:10.860 --> 03:12:11.890
Aveen Mahon: section

1867
03:12:12.130 --> 03:12:13.110
of this

1868
03:12:14.170 --> 03:12:22.260
Aveen Mahon: again, i'm sure most of you know this, those of you that were at triumph for the tour when you were there in the last collaboration meeting. We've seen all of these things in person.

1869
03:12:22.670 --> 03:12:23.570
Aveen Mahon: so

1870
03:12:23.620 --> 03:12:25.279
Aveen Mahon: nothing really new there.

1871
03:12:28.190 --> 03:12:43.469
Aveen Mahon: Oh, actually, yes, One last thing is that we did have another milestone in the last couple of months since the last time. You you guys don't need to understand the details of this plot. There's a lot going on. But if you just Look at this ping curve at the bottom when it's not. At the bottom

1872
03:12:43.700 --> 03:12:47.270
Aveen Mahon: is a continuous amount of time that we ran beam.

1873
03:12:47.510 --> 03:12:56.230
Aveen Mahon: and so the largest chunk here is around 3 h, and that's a new milestone for us. 3 h of continuous high power run.

1874
03:12:56.430 --> 03:13:05.820
Aveen Mahon: but our goal ultimately is for 3 day continuous speed delivery by March, 2,023. So we still have quite some ways to go. But hopefully, the

1875
03:13:06.000 --> 03:13:08.360
Aveen Mahon: the progress that we've made on

1876
03:13:08.390 --> 03:13:10.499
Aveen Mahon: the issue. Tracking will help with that.

1877
03:13:10.870 --> 03:13:13.649
Aveen Mahon: So that's just the general status of the elite.

1878
03:13:14.110 --> 03:13:20.989
Aveen Mahon: And now onto the beam optics model. I just wanted to show a little plot here to remind us why we need

1879
03:13:21.320 --> 03:13:26.470
Aveen Mahon: optics downstream of your target. So this here is a two-dimensional plot

1880
03:13:26.600 --> 03:13:28.090
Aveen Mahon: of

1881
03:13:28.140 --> 03:13:29.809
Aveen Mahon: The section that I showed

1882
03:13:29.850 --> 03:13:32.240
Aveen Mahon: previously. This

1883
03:13:32.270 --> 03:13:34.840
Aveen Mahon: section here from the Blue Magnet

1884
03:13:35.190 --> 03:13:36.869
Aveen Mahon: all the way to the dump

1885
03:13:37.270 --> 03:13:44.690
Aveen Mahon: except it's flipped so the blue magnet would be M. Before. Which is this point right here on the left, all the way to the end of the dump.

1886
03:13:45.250 --> 03:13:47.240
Aveen Mahon: So the beam travels in this

1887
03:13:47.380 --> 03:13:50.020
Aveen Mahon: plot from left to right.

1888
03:13:50.500 --> 03:13:52.009
Aveen Mahon: and so

1889
03:13:52.230 --> 03:13:54.659
Aveen Mahon: this location, right in the middle.

1890
03:13:54.910 --> 03:13:56.600
Aveen Mahon: where you see

1891
03:13:56.860 --> 03:14:02.929
Aveen Mahon: these curves diverge, is where your target is, and these lines are. They represent the beam envelope.

1892
03:14:03.050 --> 03:14:09.409
Aveen Mahon: So that's the size of the beam in both the X and Y direction X being red and y being

1893
03:14:09.980 --> 03:14:15.350
Aveen Mahon: green, and when I hit the target. They're scattered, and so the envelope blows up.

1894
03:14:15.840 --> 03:14:24.770
Aveen Mahon: and the limits on this plot are very important, because they are the dimensions of the beam pipe that the beam is traveling through. And so, when you have here

1895
03:14:24.950 --> 03:14:26.420
Aveen Mahon: the beam envelope

1896
03:14:26.690 --> 03:14:28.379
Aveen Mahon: surpassing the beam pipe.

1897
03:14:28.630 --> 03:14:36.830
Aveen Mahon: that means that it's going to be hitting the edges of the machine, which will cause a lot of beam losses, and in turn a lot of radiation, and that

1898
03:14:37.050 --> 03:14:42.010
Aveen Mahon: basically breaks our safety protocols that are in place for the machine.

1899
03:14:43.040 --> 03:14:43.949
and

1900
03:14:44.140 --> 03:14:48.029
Aveen Mahon: to fix this we had to add certain optical elements

1901
03:14:48.170 --> 03:14:49.090
downstream.

1902
03:14:50.210 --> 03:14:54.530
Aveen Mahon: and so the requirements for the beam optics model. To correct this

1903
03:14:54.550 --> 03:14:58.289
Aveen Mahon: on broad terms are more or less, that the 3.7 sigma envelope

1904
03:14:58.600 --> 03:15:11.970
Aveen Mahon: has to be fully contained within the one in 2 point, 5, 4 cm radius of the beam pipe, so that if we're looking at this plot means this gray line, which is a slightly larger envelope than our regular 2, Sigma, the 3.7. Sigma

1905
03:15:12.080 --> 03:15:19.410
Aveen Mahon: has to stay within the bounds of this plot, otherwise we're passing our safety requirements for being losses.

1906
03:15:20.490 --> 03:15:31.739
Aveen Mahon: Then also a few other things that just are in needed for operation is, we want to minimize the beam size through the dump, and that's just based on the way that the dump is designed.

1907
03:15:31.830 --> 03:15:43.569
Aveen Mahon: We want the model to work for an energy range of 27 to 31 mev 31 of course, because that is the energy. You guys really want to work out, but also should be valid for lower energies, because sometimes, as

1908
03:15:43.810 --> 03:15:46.010
Aveen Mahon: as you know, we don't always reach

1909
03:15:46.030 --> 03:15:51.929
Aveen Mahon: 30 mev on a given day. because of the performance of this, or if cavities, crime modules

1910
03:15:52.110 --> 03:15:57.739
Aveen Mahon: all of those things, so it needs to work for, say, the lower energies for forced to operate at those.

1911
03:15:57.900 --> 03:16:03.520
Aveen Mahon: But we also had to make sure that this model was compatible with regular operation, because

1912
03:16:03.780 --> 03:16:06.250
Aveen Mahon: we do still need to operate our machine

1913
03:16:06.280 --> 03:16:09.160
Aveen Mahon: for other purposes than just your experiment.

1914
03:16:09.630 --> 03:16:27.719
Aveen Mahon: and it needs to include sufficient diagnostics elements for operation. So that last point is what has caused the change? The recent change in the last 2 weeks of the model for those of you that have probably seen the one that was presented a while ago. We had to make a few changes because we had

1915
03:16:27.730 --> 03:16:31.089
Aveen Mahon: realized we did not include enough diagnostics elements.

1916
03:16:31.250 --> 03:16:32.990
Aveen Mahon: So the new model

1917
03:16:33.080 --> 03:16:34.699
Aveen Mahon: is as follows here.

1918
03:16:35.690 --> 03:16:39.079
Aveen Mahon: So now we see at the location of

1919
03:16:39.140 --> 03:16:40.130
Aveen Mahon: the target.

1920
03:16:40.430 --> 03:16:45.270
Aveen Mahon: The beam blows up, but we have our 3 permanent magnets that we've heard about already today

1921
03:16:47.000 --> 03:16:52.919
Aveen Mahon: in a row right there and then. We've got so a diagnostics element right here

1922
03:16:53.140 --> 03:16:55.560
Aveen Mahon: in the middle, which is a VPN being position monitor.

1923
03:16:56.080 --> 03:16:58.919
Aveen Mahon: Then our 2 electromagnetic quadrupools.

1924
03:16:59.110 --> 03:17:05.109
Aveen Mahon: and then another being positioned monitor, and finally a diagnostics box that will allow for a fast wire scanner.

1925
03:17:05.940 --> 03:17:10.720
Aveen Mahon: so that we can evaluate the performance of the permanent magnets

1926
03:17:10.740 --> 03:17:16.200
Aveen Mahon: that way we'd be able to identify if they degrade over time. If they're doing the right amount

1927
03:17:16.310 --> 03:17:17.650
of focusing

1928
03:17:18.330 --> 03:17:27.699
Aveen Mahon: and the position monitors important to see where we're going when we're entering the jump. Because we don't want to be spraying beam everywhere at the wrong angles.

1929
03:17:27.860 --> 03:17:30.550
Aveen Mahon: So the overlapping lines are just

1930
03:17:30.740 --> 03:17:35.430
Aveen Mahon: all of the different energies that I listed before. So from 27 to 31

1931
03:17:35.880 --> 03:17:38.490
Aveen Mahon: it gets bigger as the energy increases.

1932
03:17:38.890 --> 03:17:45.580
Aveen Mahon: and the difference between this and the previous time. As we moved it all slightly upstream, got rid of a box

1933
03:17:46.050 --> 03:17:48.999
Aveen Mahon: that had a view screen up ahead and moved it down.

1934
03:17:49.080 --> 03:17:52.769
Aveen Mahon: So that's more or less. What? what the new model looks like.

1935
03:17:55.360 --> 03:17:55.980
Yeah.

1936
03:17:58.560 --> 03:18:01.190
Aveen Mahon: So does anyone have any questions

1937
03:18:01.690 --> 03:18:06.200
SBU CFNS: what's the

1938
03:18:07.320 --> 03:18:10.170
Aveen Mahon: so the dispersion is 0,

1939
03:18:10.210 --> 03:18:14.229
Aveen Mahon: the blue line that's just important for in the bending section.

1940
03:18:14.460 --> 03:18:19.349
Aveen Mahon: So this section from here to here, because you're you're going around the bend.

1941
03:18:19.520 --> 03:18:35.400
Aveen Mahon: That was. That was something that I corrected much earlier. A few months ago I realized that the model wasn't taking that into account, so we just had to make sure I just had to make sure that the way I was setting everything up made that this blue curve goes up, but then back down to 0 for the rest of the line.

1942
03:18:42.540 --> 03:18:45.350
SBU CFNS: okay, and

1943
03:18:46.000 --> 03:18:46.770
SBU CFNS: yes.

1944
03:18:47.150 --> 03:18:51.039
SBU CFNS: for logistics. The 2 monitoring stations

1945
03:18:51.550 --> 03:18:52.550
SBU CFNS: so

1946
03:18:52.870 --> 03:18:54.640
SBU CFNS: downstream from

1947
03:18:57.030 --> 03:18:58.899
SBU CFNS: for the permanent items.

1948
03:18:59.930 --> 03:19:01.519
SBU CFNS: How big are those?

1949
03:19:01.780 --> 03:19:16.819
Aveen Mahon: So the Bpms beam position. Monitors are not much bigger than I should have included pictures of those actually. But They're not much bigger than the permanent magnets themselves. They're quite small. the diagnostics box is fairly large. It's around the same length as the

1950
03:19:17.510 --> 03:19:21.970
Aveen Mahon: electromagnetic quadrupole. possibly slightly.

1951
03:19:22.010 --> 03:19:23.839
Aveen Mahon: It's like a large

1952
03:19:24.420 --> 03:19:27.000
Aveen Mahon: kind of square hexagonal box.

1953
03:19:27.340 --> 03:19:29.640
Aveen Mahon: but because it's the last element

1954
03:19:29.680 --> 03:19:35.909
Aveen Mahon: right at the end, it should be well clear of your your spectrometers by that point, I believe.

1955
03:19:37.660 --> 03:19:39.820
SBU CFNS: Yeah, I I

1956
03:19:40.400 --> 03:19:45.490
SBU CFNS: It's it's downstream of the the the to try.

1957
03:19:45.790 --> 03:19:51.930
Aveen Mahon: Yeah, yeah, it's another 20 to 30 cm further downstream. So

1958
03:19:52.120 --> 03:19:56.380
Aveen Mahon: if there should be sufficient space. But I believe I sent the

1959
03:19:57.830 --> 03:20:00.169
Aveen Mahon: yeah, yeah.

1960
03:20:00.210 --> 03:20:06.740
Christopher J Vidal: the best way to check that would be to have Chris integrated into the CAD model.

1961
03:20:06.960 --> 03:20:13.330
Christopher J Vidal: I started working on our already. thank you very much for being the the model you gave me is excellent.

1962
03:20:13.630 --> 03:20:20.570
Christopher J Vidal: there's a lot of detail in it, so it takes me while to dumb it down. But to answer your question, Doug, the VPN. Look

1963
03:20:20.690 --> 03:20:26.410
Christopher J Vidal: almost identical to the kind that we had at base, and about the same size

1964
03:20:26.570 --> 03:20:37.789
Christopher J Vidal: diameter. Wise they look to be on the order of like 3 to 4 inches length. Wise they They're not very long. I think they'll fit in there fine and

1965
03:20:38.190 --> 03:20:40.160
Christopher J Vidal: the large rectangular

1966
03:20:40.300 --> 03:20:42.030
Christopher J Vidal: diagnostic

1967
03:20:42.210 --> 03:20:47.549
Christopher J Vidal: on its own stand and everything I put in next to the dump, and it seems like it's gonna fit my

1968
03:20:47.920 --> 03:20:52.360
Aveen Mahon: here. I'm going to try to find I have pictures that I should be able to find fairly

1969
03:20:53.320 --> 03:20:54.449
Aveen Mahon: quickly

1970
03:20:57.420 --> 03:20:59.859
Aveen Mahon: here. If you'll just give me a moment.

1971
03:21:14.690 --> 03:21:15.910
Okay, yeah.

1972
03:21:16.330 --> 03:21:17.760
Aveen Mahon: So this is the

1973
03:21:18.040 --> 03:21:19.369
Aveen Mahon: VPN:

1974
03:21:26.180 --> 03:21:27.159
SBU CFNS: Oh, okay.

1975
03:21:28.270 --> 03:21:31.319
Aveen Mahon: hold on! Let me see what it's.

1976
03:21:31.650 --> 03:21:37.440
Aveen Mahon: Actually, this is the diagnostics box. So here you see Delta X, 1 14 so it's 11.

1977
03:21:37.800 --> 03:21:41.999
Aveen Mahon: that's 11 cm is the width, and then you can

1978
03:21:42.550 --> 03:21:46.390
Aveen Mahon: gauge the height. It goes with it beyond the bounce of the screen, and then the vpm.

1979
03:21:46.890 --> 03:21:49.090
Aveen Mahon: One is this one here

1980
03:21:49.620 --> 03:21:52.070
Aveen Mahon: which is only 3 cm

1981
03:21:52.870 --> 03:21:55.780
Aveen Mahon: so quite small this section

1982
03:21:57.390 --> 03:21:59.530
Aveen Mahon: so 3 cm wide, so probably.

1983
03:22:01.360 --> 03:22:03.870
Aveen Mahon: or something

1984
03:22:04.930 --> 03:22:05.770
SBU CFNS: right?

1985
03:22:06.290 --> 03:22:09.880
SBU CFNS: Thanks any other questions to really

1986
03:22:12.400 --> 03:22:13.960
SBU CFNS: our concerns.

1987
03:22:15.200 --> 03:22:15.820
SBU CFNS: No.

1988
03:22:17.290 --> 03:22:21.840
SBU CFNS: you're welcome.

1989
03:22:24.690 --> 03:22:25.530
SBU CFNS: Okay.

1990
03:22:46.430 --> 03:22:48.890
SBU CFNS: let's talk shielding

1991
03:22:54.030 --> 03:22:55.969
where you guys can actually

1992
03:23:01.060 --> 03:23:01.730
what we done.

1993
03:23:05.920 --> 03:23:06.680
Okay.

1994
03:23:07.410 --> 03:23:08.080
Thanks.

1995
03:23:15.200 --> 03:23:30.840
SBU CFNS: Because it's not a leisure pointer. Yeah, it's the same thing that communicates the Mac Mini that it says, oh, well, but it's not If it's a TV that leisure pointer. Also it it will see it on line, and you you won't see it online, either. And it's a it's a it's a

1996
03:23:31.110 --> 03:23:31.810
and open.

1997
03:23:31.950 --> 03:23:39.039
SBU CFNS: It's. It's it's it's bizarrely. Maybe it's got a driver's going it something

1998
03:23:39.110 --> 03:23:44.159
SBU CFNS: yeah, to know where you're since I know you're pointing. I don't know it is.

1999
03:23:46.670 --> 03:23:52.990
SBU CFNS: It's like

2000
03:23:53.490 --> 03:24:06.470
SBU CFNS: okay, so we wanted to talk a little bit about the shielding, because this is going to be a relevant thing for us to be up, and it sounds like it's something we could potentially use for our requirements.

2001
03:24:09.910 --> 03:24:12.649
SBU CFNS: Oh, because you're using the this already.

2002
03:24:12.800 --> 03:24:15.449
SBU CFNS: Sorry! No, I I have this open

2003
03:24:15.480 --> 03:24:24.299
SBU CFNS: and say, open No, no, no, No, no, no, no, no, no, no right click right here.

2004
03:24:24.470 --> 03:24:26.290
SBU CFNS: open and open with

2005
03:24:27.580 --> 03:24:32.410
SBU CFNS: course, I shared this apart in my head. So, you guys.

2006
03:24:32.590 --> 03:24:37.389
SBU CFNS: and then just

2007
03:24:37.430 --> 03:24:42.470
SBU CFNS: and this share the whole screen, this desktop one. It's just a

2008
03:24:42.960 --> 03:24:47.050
SBU CFNS: So we have all things

2009
03:24:50.670 --> 03:24:53.590
SBU CFNS: private emails

2010
03:24:53.780 --> 03:24:54.390
terrible.

2011
03:24:57.870 --> 03:24:59.789
SBU CFNS: Okay.

2012
03:24:59.810 --> 03:25:02.729
SBU CFNS: Now, I think we're actually

2013
03:25:02.750 --> 03:25:10.709
SBU CFNS: yeah, only if it's going to get in your way.

2014
03:25:11.370 --> 03:25:30.439
SBU CFNS: So what I wanted to point out is that obviously we are concerned with shielding because we need to protect our electronics and our vectors. But the lab is in the shielding, for unrelated. Essentially one is protecting the accelerator and other components there. An additional radiation that we might cause like anything we're doing beyond what is already exposed to

2015
03:25:30.450 --> 03:25:50.170
SBU CFNS: which could either damage components that we have there, like the camera and diagnostics, box, or and or will cause the activation, and whereby material, which is that it's going to be so. They care about that element of it. And then obviously in addition to sort of activation, radiation, there is prompt radiation. If it's so bad

2016
03:25:50.180 --> 03:26:05.930
SBU CFNS: that you have to worry about

2017
03:26:06.410 --> 03:26:16.860
SBU CFNS: the shielding makes that we have in this sense the entirety, all is considered shielding, like all of the conference around it, is built into the bottles.

2018
03:26:17.190 --> 03:26:20.750
SBU CFNS: but what we will need to do is demonstrate that whatever we are going to do.

2019
03:26:20.880 --> 03:26:31.179
SBU CFNS: which both includes removing some existing shielding and having a new shielding and adding a target and adding an experiment. We'll stay compatible with the last environments on all the things.

2020
03:26:31.470 --> 03:26:46.529
SBU CFNS: So what we need to accomplish for sort of human safety at the time is laid out very clearly in a

2021
03:26:46.750 --> 03:26:57.259
SBU CFNS: so like I mentioned, maybe call. This is an accessible area, but there are some nearby the nearest high up I've been. It's pretty far away, but there is some low occupancy ones in that area

2022
03:26:57.550 --> 03:27:06.190
SBU CFNS: and trying to find it for the nearest low occupancy uncontrolled area like the corridor is that it must have to us right under 10 micro secrets per hour.

2023
03:27:07.140 --> 03:27:12.449
SBU CFNS: We, I think there's no realistic possibility that us having the assignment to this.

2024
03:27:12.760 --> 03:27:19.759
SBU CFNS: All is going to change the radiation levels in any of these places in any measurable way. But we still have to.

2025
03:27:20.370 --> 03:27:21.300
SBU CFNS: So

2026
03:27:21.480 --> 03:27:33.959
SBU CFNS: because it's more simulation. We're just going to see. There are no particles there, all like, but not this is where the flu got an expert

2027
03:27:33.970 --> 03:27:51.009
SBU CFNS: activation housing this one will be potentially more relevant for us. the requirement here is that the residual radiation field must be under 100 micro secrets an hour at 50 cm from the edge and shielding our.

2028
03:27:51.080 --> 03:28:00.470
SBU CFNS: So it's actually

2029
03:28:01.520 --> 03:28:02.199
alright.

2030
03:28:03.760 --> 03:28:22.060
SBU CFNS: I'll know here, and we're also asked to figure out what extent the components of our

2031
03:28:22.390 --> 03:28:23.159
so

2032
03:28:23.490 --> 03:28:24.320
SBU CFNS: fair enough.

2033
03:28:24.600 --> 03:28:34.220
SBU CFNS: right? So how do we do that? Generally what the lab wants is what that which is set up to do both the prompt radiation and the clear activation radiation.

2034
03:28:34.250 --> 03:28:37.009
SBU CFNS: there is a model of the email and the down

2035
03:28:37.330 --> 03:28:44.399
SBU CFNS: with existing shielding that exists and detailed studies. We're done on this when we design out that that was in 2,013.

2036
03:28:44.480 --> 03:28:48.539
SBU CFNS: So it's there's a bit of legacy home situation here.

2037
03:28:48.660 --> 03:28:53.819
SBU CFNS: the ideal scenario for us would be to basically just get the models that were used at that time.

2038
03:28:54.170 --> 03:28:58.089
SBU CFNS: Add directly we run, reduce existing plots.

2039
03:28:58.180 --> 03:29:12.069
SBU CFNS: The great thing here is, the studies are done with the 100 kilowatts. When all of the original safety documentation is done, we know that our plan is not run more than 10 and so this actually gives us a lot of

2040
03:29:12.470 --> 03:29:26.539
SBU CFNS: but no, also we're going to have to do all of this all over again for the new being that configuration. If we may be running again, we're gonna have to move things to the shielding we have to meet or anything. but probably what if we design now? We'll work that you?

2041
03:29:26.640 --> 03:29:29.260
SBU CFNS: It's the

2042
03:29:30.150 --> 03:29:31.280
There are

2043
03:29:31.350 --> 03:29:34.539
SBU CFNS: smaller than the existing.

2044
03:29:34.760 --> 03:29:53.450
SBU CFNS: The the second phase would be actually right into. Let the head for a 100 to one. Because that's why together it would be that although the one we have now could never be used for the

2045
03:29:53.460 --> 03:29:54.949
and that is

2046
03:29:55.590 --> 03:30:06.729
SBU CFNS: so. Basically it's it's an existing copy of the current dump, because it's this one that we have in the hall right now. It's

2047
03:30:06.740 --> 03:30:30.749
SBU CFNS: I thought that was. I thought there was some licensing people that you know hadn't seen the tests or something different. This i'm not sure. But this is what I remember to. We had a couple of weeks ago, 10 months in the background of of conversations, as though this is not the case. But I don't know what the baby was, and he would say it was

2048
03:30:30.760 --> 03:30:47.140
SBU CFNS: he originally told me.

2049
03:30:47.190 --> 03:30:54.289
SBU CFNS: and I don't believe that needs our plan.

2050
03:30:56.210 --> 03:30:57.080
SBU CFNS: Is it

2051
03:30:57.520 --> 03:31:01.119
SBU CFNS: a pipe dream? Or is it actually

2052
03:31:01.140 --> 03:31:04.810
SBU CFNS: the code that generated the flu good results that

2053
03:31:04.990 --> 03:31:13.700
SBU CFNS: trial accepted when saying with the shielding, but that all sufficient Still.

2054
03:31:13.820 --> 03:31:30.270
SBU CFNS: one person who might have it on Wednesday morning that you sure it is that that is, that is great, is it? On the desktop computer? The guidelines kind of all the questions I have about like, how do we prove this to prime satisfaction?

2055
03:31:30.280 --> 03:31:51.309
SBU CFNS: And it shows you some really interesting safety reports. It's an example of how people proved that to try and satisfy

2056
03:31:51.320 --> 03:32:03.809
SBU CFNS: we have

2057
03:32:04.330 --> 03:32:11.099
SBU CFNS: discipline which I think I actually never announced to you. Existing simulations like I said, this is the existing model

2058
03:32:11.390 --> 03:32:22.430
SBU CFNS: that is in a program somewhere for the geometry here being dumped in the dark place. So you recognize this immediately. This is where we're going to put it. This is the chunk of children that we need to move

2059
03:32:22.440 --> 03:32:33.460
SBU CFNS: which will be approval, for i'll show you why it's there at the moment, and then we've got elements of the wall and so on, and then the okay. So ideally, we would just pop that out, pop in the new model bring about everything

2060
03:32:33.590 --> 03:32:34.590
his dream.

2061
03:32:35.090 --> 03:32:37.119
SBU CFNS: this is what the

2062
03:32:37.450 --> 03:32:41.550
SBU CFNS: simulations directly look like doing that. So the the code.

2063
03:32:41.640 --> 03:32:52.390
SBU CFNS: should we be able to find it. pretty much just as this. And then you get dos in whatever unit in all of these different locations

2064
03:32:52.430 --> 03:32:55.470
integrate it and see that you actually do it.

2065
03:32:56.420 --> 03:33:02.149
SBU CFNS: this I wanted to show you, because this is something we'll have to address, which is taking out the current shielding wall.

2066
03:33:02.260 --> 03:33:16.940
SBU CFNS: You can kind of see in this image one. It's here this a huge amount of radiation back off the dump. and here I think it's where the diagnostic box with the camera in it currently is, and that camera can only with down. So much so. This is essentially protecting that equipment.

2067
03:33:17.090 --> 03:33:24.829
SBU CFNS: But this is that at a 100 to us, and at 10 we're almost certain we don't need it, so we'll be able to take it

2068
03:33:24.870 --> 03:33:34.689
SBU CFNS: and and we use it. This document actually.

2069
03:33:35.520 --> 03:33:48.829
SBU CFNS: yeah, this is also, though I wanted to point out, and I think I've been mentioned this, but i'm not certain. There's a very good chance that we will be asked to add the camera from that box to dark light, because, in order to get everything in when you take that out.

2070
03:33:48.840 --> 03:33:58.439
SBU CFNS: and then they still need something where they can physically look at it in time. Next screen, which we are going to have. So we might use that camera to be looking in at our screen.

2071
03:34:00.000 --> 03:34:18.689
Aveen Mahon: I can comment on that a bit, because yeah, we basically removed a view screen box from the layout to move it all upstream. But that was based on kind of the assumption that even in your target ladder that you have right now you have a scintillator screen on there that we use to look at the beam spot.

2072
03:34:18.700 --> 03:34:22.670
Aveen Mahon: So if it was something similar to that, even would probably be

2073
03:34:22.880 --> 03:34:26.910
Aveen Mahon: would be enough for us to at least just see whereabouts. The beam is on

2074
03:34:27.300 --> 03:34:30.869
at that location, and then go through it doesn't necessarily need to be the exact same camera

2075
03:34:31.110 --> 03:34:35.689
SBU CFNS: perfect, but given that it exists. And

2076
03:34:37.130 --> 03:34:45.039
Aveen Mahon: but I think it was. The the assumption was that it would need to be on your target ladder like in like.

2077
03:34:45.410 --> 03:35:01.370
SBU CFNS: No, it doesn't need to be a camera. It's it. It could just it's a view screen. Yeah, yeah, like the one that's already there on on your currently

2078
03:35:01.380 --> 03:35:10.339
Aveen Mahon: right now that we would move as a maximum. Yeah, so that that one we would probably just remove entirely, and

2079
03:35:10.530 --> 03:35:14.010
Aveen Mahon: use this like a scintillator screen, or something like that on your target. There.

2080
03:35:14.040 --> 03:35:19.640
Aveen Mahon: That would.

2081
03:35:20.960 --> 03:35:21.900
Aveen Mahon: That's true.

2082
03:35:21.950 --> 03:35:23.620
SBU CFNS: So

2083
03:35:23.700 --> 03:35:24.449
SBU CFNS: yeah.

2084
03:35:25.680 --> 03:35:27.520
SBU CFNS: that's that's the issue.

2085
03:35:28.080 --> 03:35:30.760
SBU CFNS: So then we need to.

2086
03:35:30.870 --> 03:35:39.560
SBU CFNS: Yeah, there's 2 ports on the standard chamber. One is blocked by something else

2087
03:35:39.620 --> 03:35:49.259
Christopher J Vidal: no longer. No, because it was, it was blocked by the diagnostics box, which is now getting

2088
03:35:49.440 --> 03:35:59.879
SBU CFNS: okay. Okay, that's yeah. So there's 2 ports. One, we thought would be for a optical camera and the other we thought her name for Red.

2089
03:36:00.170 --> 03:36:08.920
SBU CFNS: and it's like Again, we we might just release this one

2090
03:36:16.480 --> 03:36:17.280
37.

2091
03:36:18.060 --> 03:36:38.300
SBU CFNS: okay. So what we will have to put together is a shielding design note, which will include all the details of the simulation of what we actually plan on building for our shielding and then we'll have to put together a safety analysis report. This is a briefer summary, which is more focused on communicating everything, describing modification of the existing facility. What we're going to add to the design expected doses. But sort of the the

2092
03:36:38.520 --> 03:36:46.439
SBU CFNS: less crazy summary that is the important one that the lab is going to really read and track, and by the

2093
03:36:46.480 --> 03:36:52.620
SBU CFNS: I have examples of both. If you guys want to take a look at them, we can do that. But that's more or less we have to put together.

2094
03:36:52.640 --> 03:36:58.829
SBU CFNS: So as we just said in the design Review again, 5 min so we used to have up with the X-ray client. They are gone.

2095
03:36:59.360 --> 03:37:12.020
SBU CFNS: Stephanie and I are going to meet nicely with the students. So what he did is he tested the design work flash Which was an experiment that ran last year, and a very

2096
03:37:12.560 --> 03:37:15.930
SBU CFNS: that is doing variation of my

2097
03:37:16.080 --> 03:37:18.320
so

2098
03:37:18.530 --> 03:37:25.610
SBU CFNS: similarly.

2099
03:37:26.090 --> 03:37:38.020
SBU CFNS: and I didn't see the exact same thing, and I didn't see the exact same thing. But I did see it so I My hope is this: soon as that.

2100
03:37:38.090 --> 03:37:40.469
and we just need to put these things together, but

2101
03:37:40.930 --> 03:37:43.409
SBU CFNS: our experiment in there instead.

2102
03:37:43.600 --> 03:37:44.300
Yes.

2103
03:37:44.410 --> 03:37:50.279
SBU CFNS: he doesn't know if we know what we can do, what we do have.

2104
03:37:50.450 --> 03:37:56.030
SBU CFNS: Hopefully, you'll be able to with this, and then you can just

2105
03:37:56.070 --> 03:37:56.800
exactly

2106
03:37:58.670 --> 03:38:07.559
SBU CFNS: Yeah. And then I wanted to say that I yeah, i'm not sure whether they started from the code that we showed thoughts from here. I don't know how we set, and we can change, but we will try to have. An

2107
03:38:08.200 --> 03:38:18.510
SBU CFNS: so this is the plan for what kind of me to see. Presumably we could use the same program as we thought it set up the

2108
03:38:18.910 --> 03:38:21.549
I don't think that would be that much worse. But

2109
03:38:25.220 --> 03:38:25.810
that's fine.

2110
03:38:25.940 --> 03:38:27.620
Alright, that's fine.

2111
03:38:37.250 --> 03:39:02.299
SBU CFNS: up again. It it turns out that we actually have both the person who can run it and the models we need to

2112
03:39:02.330 --> 03:39:10.070
SBU CFNS: the same. That's troubling.

2113
03:39:10.240 --> 03:39:19.570
SBU CFNS: Okay.

2114
03:39:19.970 --> 03:39:22.330
SBU CFNS: but you know.

2115
03:39:22.370 --> 03:39:30.519
SBU CFNS: it might be a problem when you're trying to verify that you set up is correct.

2116
03:39:34.250 --> 03:39:39.820
SBU CFNS: Okay. So what what from today's schedule is not?

2117
03:39:40.220 --> 03:39:48.689
SBU CFNS: so you can be sure it has put together a discussion of the They're the postal phone over our software framework, and it's a little bit details I i'm not sure

2118
03:39:48.850 --> 03:40:04.770
SBU CFNS: I would. I think i'd rather take that rush rather than I think the move on it's it's really it. to talk AIM to kind of.

2119
03:40:04.940 --> 03:40:14.759
SBU CFNS: I would like to that here, too, but I might ask that, Doug, who seems keen to modify the schedule.

2120
03:40:15.490 --> 03:40:24.449
SBU CFNS: basically Add this in, and then we can say that today's schedule has been successfully tired, and we've done all the things we need to talk about today.

2121
03:40:27.150 --> 03:40:29.210
SBU CFNS: I think it's probably already dark. That

2122
03:40:29.680 --> 03:40:31.699
so? Yeah.

2123
03:40:31.830 --> 03:40:45.550
SBU CFNS: we we could bring out the

2124
03:41:09.020 --> 03:41:10.200
SBU CFNS: what is the benefit?

2125
03:41:10.490 --> 03:41:23.749
SBU CFNS: What is it? Well, you know, we actually

2126
03:41:23.760 --> 03:41:43.160
SBU CFNS: okay, All right. How are you taking me to adjourn and thank you to people online. Yeah, thanks. Have a good dinner, bye. Yeah, thank you. Thank you. Have a good one there.

2127
03:42:03.630 --> 03:42:17.219
SBU CFNS: They constantly leave this stupid mouse up here, and the stupid mouse doesn't control the computer. Yeah, like it is. No, no. I keep doing this. Yeah, like

2128
03:42:17.320 --> 03:42:21.249
SBU CFNS: it needs to. It needs to go entirely away.
