Current state-of-the-art in high power Cyclotrons/FFAs

H$^-$ cyclotrons, such are TRIUMF 500 MeV machine, are essentially characterized by their large phase acceptance. Since beam extraction relies on charge exchange (H$^-$ to H$^+$) no turn separation is required. Bunches typically occupy several tens of degrees of rf phase, and consequently acquire, during the acceleration process, a large energy spread. This large energy spread leads...

Current state-of-the-art in high power Cyclotrons/FFAs

The RIKEN RI Beam Factory (RIBF) is the world's most intense heavy ion accelerator facility based on cyclotrons. We have been operating this facility for 16 years with increasing intensity especially of very heavy ions such as uranium ion. I will report operational experience with the cyclotrons, including problems, failure, and reliability.

Applications of high power Cyclotrons/FFAs

A 70-MeV proton cyclotron system (C70) will be installed this year in the ISOL building of Institute for Basic Science, Korea. We made a contract with IBA in June 2019, and the contract will end with site acceptance tests in the middle of 2022. Currently, one beam line is prepared for ISOL target while two target bunkers are constructed. In addition, some area is available for different beam...

32. The High Intensity Proton Accelerator Facility at PSI. Past, Present, Projects.

Joachim Grillenberger (Paul Scherrer Institute)

Current state-of-the-art in high power Cyclotrons/FFAs

The High Intensity Proton Accelerator Facility at PSI routinely produces a 590 MeV proton beam with currents of up to 2.4 mA.
The 1.4 MW beam is used to generate neutrons in spallation targets, and pions in meson production targets. The secondary particles are used for condensed matter and particle physics research at the intensity frontier. This presentation will give an overview of the...

1. Major limitations of fixed field particle accelerators

Current state-of-the-art in high power Cyclotrons/FFAs

While the best known utilizations of particle accelerators are associated with high-energy physics, a growing number of applications such as heavy ion therapy, energy amplifiers and neutrino factory rather rely on producing high intensity charged particles. For instance, cyclotrons existed since the 1950s and demonstrated their capability to achieve such high intensity beams. Nevertheless, in...
