强流RFQ加速器设计中两种设计程序的结合

Joint of Two Dynamics Design Codes for High Current RFQ

摘要: 在以强流空间电荷效应为主的射频四极加速器RFQ的束流动力学设计中,目前有两种主要的设计模式,LANL开发的设计程序Parmteqm和俄罗斯RTI开发的Lidos.RFQ。强流RFQ的设计应充分发挥二者的优点,将其结合起来。本工作在1台3 5MeV、352MHz、60mA强流质子RFQ的物理设计中,充分发挥这两种设计模式的特点,开拓新的设计思路,获得了满意的设计结果。

Abstract: There are two codes for the dynamics design of high c urrent RFQ accelerator, which are Parmteqm from LANL and Lidos.RFQ from RTI. Dur ing the beam dynamics design of China high current RFQ which is a RFQ machin e of 3.5 MeV60 mA352 MHz, jointing two codes is tested to develop the charac teristics of tow codes together. Some results of design for the RFQ are shown in the paper.
