Description

A high-intensity rapid-cycling accelerator facility to produce the medical isotope products is proposed in China. To meet the injection requirements of the rapid-cycling synchrotron, an H-mode DTL structure with transverse focusing is adopted to compensate the space-charge effect and maintain high beam quality. In this paper, the physical design of the drift tube linac (DTL) is presented. A novel design method for DTL accelerators, which enable rapid global optimization of all cavities and efficient evaluation of multiple cavity parameters, is introduced first time. Beam dynamics simulation results show that the designed beam transmission 100% was obtained with the low emittance growth.
