The SC230 superconducting cyclotron was designed for the JINR medical research programme implementation. The accelerator is able to provide an intense beam for a new and promising flash therapy method.
The SC230 is an isochronous four-sector compact cyclotron with a 1.7-T magnetic field in the center. Superconducting coils will be enclosed in a cryostat, all other parts of the cyclotron are “warm”. Acceleration is performed at the fourth harmonic mode of the accelerating radio-frequency (RF) system consisting of four resonators located in cyclotron valleys. The accelerator will use an internal Penning-type source with a hot cathode, and the low magnetic field makes it possible to use the external axial beam injection. The results of computer simulation of cyclotron systems are presented.
