09:58:55 Hey,
09:58:58 good morning.
09:59:37 Let's see.
10:01:13 So far we're still missing. Bobby
10:01:18 there Yes, okay.
10:01:22 I think we're all here now.
10:01:24 So, Michael get started. Amen, anything new to report.
10:01:30 Yeah, I gave a talk yesterday at a one seminar.
10:01:36 So I talked about everything I have all the analysis I've done for the, for the cross section measurement.
10:01:44 We agreed on that, it's necessary to perform field map measurement.
10:01:50 Basically we're more.
10:01:59 Basically, we're the spectrometer is at. More precisely, as all the angles. Instead of just reading out of the spectrometer angle and however I seem Dears, currently conflicts between the university's policy uncovered and policy in a one Hall working
10:02:14 so basically University requires no two person working in the same room bio, In a one horse, it's required to not to work alone. So basically they cannot do it right now.
10:02:29 Next week we're going to next week to a one seminar, people are going to discuss about the future plans, so probably will have more detailed discussion of how to proceed to perform this measurement in the near future.
10:02:47 But we agreed on. This is necessary as, and this is relatively urgent to do.
10:02:55 Okay, it's good that they agree with you, and that it will happen. Question or just when.
10:03:06 Yeah, so I was in the meeting until 10 o'clock on the head of teams so yeah I thought it was nice presentation I know Jaan, I had to leave you on made a suggestion of using a Seattle lied which I thought was interesting.
10:03:19 I mean is that, I mean I know you want to do the complete fail map but I guess my feeling is to keep moving on, on the analysis as much as you can. I think these posts, these, these, these two things are talking about in some sense right so yeah your
10:03:39 life gets the better angle. Yeah, absolute angle and the field map gives them the relative angle and the acceptance and both the spouse needs to be lovely.
10:03:51 That was my feeling I thought was a good, a good a good suggestion.
10:03:51 So, I assume that can happen once once access is made for Hall.
10:04:08 I've been to. So, I think, you know, human you should just, you know, start writing your thesis proceeding ahead doing the things you can. Yeah, well you awake, while you were away This is Claire you need us and I think it'll calm and think the lab understands
10:04:14 that but you know obviously in these times it's hard to to schedule it with great accuracy. But yeah, I thought the presentation was very, very well I mean I think you've done a really good job on the analysis and you know the final results obviously
10:04:28 will depend on these. These measurements.
10:04:35 Okay.
10:04:36 Anything else for minds.
10:04:44 then keep up.
10:04:47 So tomorrow at 10 o'clock, we have a meeting with the daisy research director.
10:04:58 And I think it'll be a very short meeting but we're all welcome to attend.
10:05:03 It will be.
10:05:21 I expect him, explaining why we're not invited to the PRC and what that he's still that they're still interested in running the measurements at the testing facility.
10:05:20 And, you know, just updating us on the current situation.
10:05:27 On Monday I heard from OVA who spoke with Marcel, who's one of the coordinators for the test Spain, and they're now set up to do the
10:05:42 extracted being tested and Judy are vague.
10:05:48 You know, which should have happened a year ago but because of one thing and another anyway they're all set up the it's bins surveyed they've got the interlocks installed and checked.
10:06:04 They're just waiting for the go ahead from the Hamburg authorities to the run this beam line.
10:06:13 And this is a necessary step before they do any further planning to build an extract that been lying, going into fall, too. So, so there's been some progress.
10:06:33 Not too much happening on T Beck's.
10:06:39 As you know I'm teaching tomorrow's I can't make the meeting, I mean I think what's important is to get across the teeth, the commitment of the collaboration, and the site you know the science.
10:06:52 Review which was very positive and the fact that no other lab is, you know, is, is in a position, I mean there's a lot of interest that Jay lab there's a lot of letters of intent there's even approved conditionally approved proposals now use positrons
10:07:06 but there's no.
10:07:09 You know, this one plan, actually I learned that to essentially use Hall see and redo the class classics, I guess. By then, experiment type of thing. In horsey horsey.
10:07:27 Yeah.
10:07:45 Okay, that I've heard. Yeah pocket on Bogdan Bogdan comes up with all kinds of ideas yeah that's
10:07:41 reasonable. It seems to have enough space to put in a lot of shielding and it might actually be the better version of that for them. Okay.
10:07:52 But, I guess, tomorrow I would really try to impress on him, you know, because the case for tea bags and keeping it, you know, having some past to the future you know even if it's tentative and we understand that and and also like on the positron source
10:08:10 in the end they need outside help to make a positron target or source or whatever they needed to kind of reiterate that. Yeah. Can you remind me again when is it tomorrow.
10:08:21 10 o'clock 10 o'clock I think.
10:08:25 Okay, so we have a meeting at nine I hope I'm done by done. Yeah.
10:08:31 Around the zoom link. Yeah. So, okay, yeah. Okay.
10:08:35 Yeah, no, I agree don't see me online at 10 maybe shoot me an email. Yeah, okay, I'm excuse.
10:08:43 Thank you. Yeah.
10:08:48 I'm okay i think that's it for cheap x.
10:08:53 I don't think there's anything new on Olympus.
10:08:59 So dark light. Any, any feedback from all over or yeah I haven't heard anything it's kind of radio silence So, we have to decide what, What are the put the funding and or not.
10:09:16 I guess I think that's a good idea.
10:09:18 Yeah, that's kind of my inclination to, I know we got burned a little bit in the last. But
10:09:26 yeah, that's my inclination.
10:09:29 Yeah.
10:09:32 So, the, the review is on the 22nd, which is a week Thursday is that right.
10:09:42 Yeah.
10:09:43 And is there any, any revisionism on the plots for the new g mind has to do we, I guess probably it hasn't changed very much.
10:09:58 I certainly didn't rock on it, but not idea I mean it went from 3.5 to 4.2 sigma or something. So, I can't imagine it's changed.
10:10:11 It might have that band might have narrowed a little bit, but
10:10:18 I wonder if Jesse Bell or he's probably, I mean he's the one who calculated that for us.
10:10:24 We could ask him to take a look at it. Yeah, that'll be good. I'll send him an email. Okay, thank you. Happy you know he i mean he's on the dark light mailing list I assume you got that but I'll send him the 10 page proposal, and just say, you know, we're,
10:10:40 we're presenting it if there's any, any kind of major new perspective that he has.
10:10:49 Let us know.
10:10:52 And two weeks, or Friday to week I also present at try on different yeah you're giving a colloquialism. Yeah. When you get closer to send send their own the yeah I think I've been working on it on the weekend.
10:11:21 maybe bad news. Good news,
10:11:21 I, I don't know, they have no other purpose for this hall and, yeah, it's not like it's not like Jay lab where.
10:11:29 I mean, it costs them nothing to say yes. Right. Exactly, exactly. I mean, worst case they approve it we don't get funded or something or we get we screw it up somehow, I don't know, I mean there's.
10:11:43 I don't see any downside for them to really commit we'll great commitment i mean you know it's some commitment but site huge.
10:11:53 That's good.
10:11:55 Yep.
10:12:00 Okay. The other thing that I have is the streaming readout workshop is in about two weeks from now starting on the 28th of April running to the 30th.
10:12:17 We're in the process of setting up talks and presentations by various people it's been advertised
10:12:29 to the user group to end user group band it's on their calendar.
10:12:48 And we've had a few people volunteer to give talks, we need to twist a few arms still I think, did you mention this in the three or proposal Doug.
10:12:51 Yeah, I think I did.
10:12:53 Yeah, I'm pretty sure I did. Okay. I'll check.
10:12:57 Yeah, no, I think it's a good thing to highlight. Yeah.
10:13:02 Yeah, it's under yeah I see but ok now let's move on. Yeah. Oh, check.
10:13:11 Okay, so anything else before going to.
10:13:18 So the the APS meeting starts later this week is that right yeah Saturday.
10:13:24 But the GHPN starts tomorrow I think what would be useful. I mean, we can all do this today. That's today.
10:13:36 What would be useful is, if somebody could put together all the, all the talks and the times. Yeah, and send it to the group, I mean I I could we can all do this separately but I'll do it I actually said I would send around.
10:13:54 Okay. No, no, it's just useful to have it all in one place so like, you know, Fox and there's a lot of other things going on so it's kind of nice to have, have it all summarized, I mean that you don't have to give a lot of information just the name and
10:14:10 the maybe the topic and the time. Yeah, with the usual Thanks. Yeah.
10:14:18 Yeah, cuz I think pretty much everybody's talking. Yeah.
10:14:22 Which is good you know that's good.
10:14:23 Yeah, no, I already said I would do this for the capex group, so that we could all cross reference our, in our presentations.
10:14:42 Yeah, actually I give the overview talk for Keith x. But, again, gives us the target talk before me so it's a little disorganized but doesn't matter.
10:15:01 Okay. Anything else.
10:15:08 Otherwise, we go on to class 12.
10:15:13 Yep, sounds good to you later.
10:15:17 Okay, bye bye. Bye.
10:15:22 So, the first thing I wanted to mention was that I was approached by Brandon Clary, who is a postdoc at Lawrence Livermore National Lab.
10:15:33 Since last August and he had worked on.
10:15:37 He got his PhD at UConn with Kim zones group and of course had worked with our group.
10:15:43 I think he did fine analysis being spent a cemetery, but he, he, this position at Livermore allows him to spend something like 20 25% of his time on anything he wants to work on, which is kind of a nice arrangement so he approached me about working with
10:15:58 us on class 12 analysis.
10:16:01 So I talked to him yesterday. And I think we're both happy to do that he would like to focus on the file analysis with Patrick, and I know Patrick supportive.
10:16:13 So I think
10:16:17 I encouraged Patrick and Brandon contact and decide how you want to work or.
10:16:25 But I think it's, it's a positive development, so we'll have more more horsepower on the, on the class 12 analysis.
10:16:36 Sounds good.
10:16:41 So I don't know Patrick Did you, I don't know if you've had a chance to interact with them.
10:16:47 No, I have not reached out to him yeah I'll email them today.
10:16:49 Yeah, I mean we have interacted in the past obviously with the five stuff and, you know, so he's somewhat of an expert. He is an expert on this stuff so having him on board would be really helpful.
10:17:01 Probably for me the most probably for all of us too.
10:17:21 Yeah, no, I think he he's really wants to work with you on the cross section extraction which is, which I think is exactly what you want so it's kind of Win win.
10:17:16 Yeah, I agree, that'd be great.
10:17:21 Anything no one.
10:17:23 Do you want to report on the analysis or anything.
10:17:27 I have mostly been focusing on stuff for APS so.
10:17:32 So really just kind of compiling what I've done in the past. No, no updates.
10:17:39 Okay.
10:17:39 Yeah.
10:17:41 Good, thanks, Bobby anything.
10:17:45 Yeah, I, you know, gave a talk last week about kind of what's going on with my work and what's going wrong with my work, and over the weekend submitted.
10:18:13 Another moderate to large scale batches simulations to try and get at basically different kinematic Ben that has higher statistics and actually I'm not sure if it's if things are running correctly on Osg, so we'll have a meeting later today with mercy
10:18:32 So, you know, be great if that resolves this discrepancy have but other than that still trying to figure out what exactly it is I'm doing wrong.
10:18:43 And if there's something else to say.
10:18:49 Guys, I guess let's leave it at that.
10:18:53 Your presentation why well I think we have to nail is missing elusive factor doll.
10:19:00 Oh, yeah.
10:19:02 I mean one one idea which I thought was interesting was to compare with the VCs right there process that same bikes working on. I mean, you know, compare aspect by aspect you know the luminosity the electronic, I don't know we but, I mean, I think this
10:19:19 is a very high priority maybe post APS, that was a group we need we need to determine that we need to straighten this out.
10:19:45 And one.
10:19:45 One area that I see, you know, that would be an easy factor is if the luminosity is wrong. And it seems like other Jayla collaborate or class co collaborators.
10:19:39 Like, it seems to me that there should be an established value of, you know, the integrated luminosity of the fall 2018 run was this value, but I don't think anyone's may be looking like no one seems to care, I guess so.
10:20:00 Yeah but, I mean, so you must be I mean the obvious thing is to compare with another process the VCs The other thing is elastic scattering, the same data set, kept that somebody calculating the elastic EP elastic cross section in this data set with what
10:20:06 luminosity do they use. I mean there's some very basic cross checks. I think we have to kind of jump on this. That's way too late, is over but I think, really.
10:20:18 I mean, we gotta go we gotta get a closer than this, for sure. Absolutely, yeah, I know I you know, I know you've worked on it you're frustrated with a little bit but we will all help, we will figure it will figure this out.
10:20:32 Yeah, great. Yeah. Okay, that's it.
10:20:36 Thanks time back anything.
10:20:40 Yes. So, I presume to my slides to explain my analysis notes for de de ue process working we're meeting
10:20:54 that this is what they call release notes about the flights. So, this religion that was approved.
10:21:01 And then they recommended me, or they require me to put the preliminary research work for my on the plot. Yeah, sure. That's great. Oh well, that's good.
10:21:14 I have to make a dry run on Thursday job.
10:21:18 Good. Well, that's the piece it stays.
10:21:24 Yeah.
10:21:25 Also, I think I should female to dB since the BMP meeting groups in the email list
10:21:36 above D VCs and arguments that I make that I have to submit as inputs.
10:21:45 The other two folks data to football start working on the VCs maximum effects.
10:21:52 Wolf agreed with his arguments, but FX suggest me to raise my conversion of existing simulation data.
10:22:04 I didn't do this.
10:22:07 Earlier issues and work on the real is this is what I have and then I'm going to submit massive simulation about the VCs.
10:22:16 There's my plan.
10:22:21 Good. Um, so pertaining to the previous discussion, have you actually extract that a cross section, like a real number for the cross section. Yes.
10:22:30 Yes. Probably the modeling here is that a detector a sentence.
10:22:37 And do you find, I mean how how close are you to what you expect.
10:22:48 And I tried with very very low number of very small number of simulation.
10:22:55 I got around to level up to no bar or a GED before to the fours.
10:23:02 That is very expected and skill of differential cross sections.
10:23:09 Some people were not happy about the detector a sentence because I present that to be so small, but I'm using only for detectors.
10:23:20 So, okay, you know just following what we said earlier with Bobby I think we need to do a side by side comparison of CS and dv pie night, you know, and compare and understand all these numbers like acceptance, and I mean at a level, you know at some certainly
10:23:41 at the factory to level or maybe battery you know we need, we need to understand these things.
10:23:49 So, so that's good. Okay, so you don't you don't find any missing orders of magnitude is what you're saying, I guess. All right.
10:23:57 Well, the thing here is that, Bobby is comparing is Richard to class 16 terms of DCMDT.
10:24:06 It says a differentiator for Section only by key.
10:24:11 And I'm doing four dimensional difference of perfection. Yeah, okay, I mean it's variables I understand, but we should compare it to some either non value or prediction or something you know we need that we need to have some anchor points for these analyses
10:24:29 that they're consistent, and you know, approximately correct at this point.
10:24:37 Right.
10:24:38 Okay, no I let's wait till after APS but I just think this is something as a group of people working on these cross we need we need to kind of get an understanding what's going on across different channels and, you know, sure we're doing things consistently.
10:24:56 Okay, good.
10:24:59 And also, tomorrow at 8:30am there will be a discussion about permanently disappeared BMP Smith retreat but there is a meeting, dedicated to delicious and tasty pie not publications case.
10:25:22 This is the one that can sentence one sentence and he was around about.
10:25:27 No, I'll see if I did today.
10:25:28 Okay.
10:25:30 Yeah, I think that one.
10:25:33 Let me share the screen
10:25:40 here here's one. So, the bird, probably get maximum FX little fight each other with
10:25:48 Andre reinforce.
10:25:51 So, wherever it is you good to see what they think of it as a timeline.
10:25:57 And then yeah,
10:26:00 this is one example that I had for the cross section.
10:26:06 Okay, so that's your two.
10:26:21 Yeah, well, we have a few of these are skill. This is expected so I was at the at the moment but we didn't try to hurt her. When you sit back there who expected it.
10:26:20 Where does that come from. Oh yeah, I compare that to class six.
10:26:26 Okay, okay. Six innocent.
10:26:29 Was it has this kind of plot. Okay, um, but I I might be wrong but Bobby said, I didn't find any from the plastics and also know about these kind of role is.
10:26:46 what do you feel about luminosity How do you calculate your acceptance, what is it I know the BBC has acceptance is different from dv pie not but, I mean, we need to understand where these large numbers are coming from and where in Bobby's case.
10:27:07 They're missing or whatever. So I think, step by step, For both these processes comparison would be, I think would be useful.
10:27:22 Absolutely.
10:27:22 Good. Good.
10:27:22 Well, I like to see meetings on publications so that's good.
10:27:33 joshing one update, please. Yeah.
10:27:39 So, this week I've been switching to the work on monitoring the like the performance of the high performance computing.
10:28:08 I'm the course. So basically Maury would like me to explore writing some script to do that more monitoring tasks and which have have not been done before by anybody all by himself so I've been learning about to related coding since about that.
10:28:26 So for the How to target simulation the gym for simulation for the target, I think.
10:28:32 I'm currently there is no further major tasks for that. And I hope I will
10:28:45 spend more time with the TV says Steve MPM analysis in the next couple of weeks or months before the, The hardware work, start in the lab.
10:29:03 Good.
10:29:05 I guess we're going to have a helium three meeting this week.
10:29:08 It's Friday.
10:29:18 Well, that was all he sent me a message last week and I said, Yeah, let's do it but he hasn't sent out an announcement.
10:29:20 Expecting there will be one. Yeah, if, if Kim's.
10:29:24 If, if James is not in the announcement. I can also do that this week to, to set up the meeting. Okay, maybe send them an email just asked him, should you send out a message, I don't know, you know.
10:29:42 Yeah, I can I can I can reach out to James to see.
10:29:45 Good.
10:29:50 Sounds good.
10:29:52 Thank you.
10:29:54 Igor.
10:29:56 Yes Hello everybody.
10:29:59 So, I'm still working on implementing a simulation for ac. in.
10:30:15 Is it seems to me that the best solution is using the beautiful boxes.
10:30:15 suggest.
10:30:29 stop the simulation. In addition, regarding not analysis.
10:30:36 There's 02 corrections that I think need to be added. The first one is a branching ratio for a by lot goes to to gamma, but it's probably not lunch correction and but looking on the previous class six analysis, the head about the 12% normalization you
10:30:59 to say a disagreement between the elastic cross section, and the measure of the Gnostic, so this also can increase.
10:31:11 Current up to date.
10:31:15 So exist in general what I'm blessed week magnified.
10:31:25 Okay, good.
10:31:29 Yeah, so we have RDVP meetings more known or Maxine will talk.
10:31:43 So
10:31:43 good.
10:31:47 Doug I just saw Karen send some feedback on the proposal, I guess. Yeah, I just read it now as well.
10:31:57 You know, I think we can get it down to 17. Yeah, it's doing something silly with me.
10:32:06 Doing something silly with me. Well I think we should address me she had these suggestions which we, which we should try and implement when we can shorten things. Yeah.
10:32:17 But, you know, Karen says we could get an extra five pages if I'm separate p Hi, but you know I love much rewrite that would entail.
10:32:39 Let's just get it into 17 pages. Yeah, yeah.
10:32:52 Yeah, I think that's, I don't think I had anything else.
10:32:57 Richard, I was, I was going to email Brandon, all I have is is Yukon email and I'm not sure if he still uses that to me for y'all forward you right after the meeting I'll forward you the email address.
10:33:13 Yeah, Great. Thank you. Sure.
10:33:13 Bobby Are you still having trouble with your computer.
10:33:20 Well, right now, there's some issues that I'm just not dealing with at the moment.
10:33:33 But it's certainly good it's certainly cranking along up too much issue
10:33:33 know clearly you don't want to make any changes before abs, but maybe I think when I get to a decent place with the cross section so we'll try and look into what's going on, more, but um yeah it's very functional for now.
