Study of separated function radio frequency quadrupoles accelerator

SFRFQ(Separated Function Radio Frequency Quadrupoles) accelerator is a new post accelerator of RFQ(Radio Frequency Quadrupoles) type,which has been developed since the beginning of the 1990s at Peking University.In order to demonstrate the possibility of the SFRFQ,a prototype cavity has been designed.A special dynamics design method has been proposed to avoid the sparking problem and decrease the energy spread at the exit of SFRFQ.It consists of two aspects:the asymmetry structure design for transverse focu...
