Description
A new radiofrequency quadrupole (RFQ) accelerator has been designed for ion therapy at the Institute of Modern Physics, Chinese Academy of Sciences. This RFQ, operating at 162.5 MHz, accelerates carbon ions to 0.8 MeV/u. To achieve a compact RFQ with high beam transmission efficiency, an adiabatic capture design and an equal-separatrix-area technique were employed in beam dynamic design. To realize an RFQ with high quality factor, high shunt impedance, and convenient maintenance, a novel plate-type radiofrequency (RF) structure was proposed and employed in RF design. In this paper, the results of the RFQ design and simulations are reported in detail.
