Abstract

Simulations are presented for a proton accelerator in which a pulsed proton beam is passed through a cascade of normal conducting cavities in a uniform magnetic field and accelerated using cyclotron resonance. To keep the accelerated proton beam in resonance with the rf fields, frequencies for successive cavities are lowered by a fixed frequency interval. It is shown, for an accelerator with a cascade of 8 cavities with 5 MHz frequency intervals dropping from 100 MHz at the first cavity in a 6.7 T magnetic field, that a 10 kV-0.14 A injected proton beam is accelerated to 0.516 GeV, with an efficiency of 73% and an average acceleration gradient of over 19 MV/m
