Fixed Field Fast Cycling 1.3KHz Permanent Magnet 30-250 MeV Synchrotron

We present a novel concept of the Fixed-Field-Alternating (FFA) small racetrack proton accelerator with kinetic energy range between 30-250 MeV made of permanent magnets. The horizontal and vertical tunes are fixed within the energy range providing very fast cycling with a frequency of 1.3 KHz. The injector is 30 MeV commercially available cyclotron with RF frequency of 65 MHz. The permanent magnet synchrotron RF frequency is 390 MHz and acceleration uses the phase jump scheme.
