摘　　要：依据感应同步加速器验证实验中的相关数据,编写程序,实现了对感应同步加速中粒子纵向动力学过程的数值模拟。针对引起加速初期束团粒子大量丢失的多个可能因素进行了计算分析,明确了各因素对粒子丢失的影响方式和程度。以此为基础,提出了通过大幅减小加速腔体积并同时增加加速腔数量的方式来解决感应同步加速电压幅度实时调节困难的可行性建议,为感应同步加速器的性能提升提供了参考。Induction synchrotron has been a focus of improving the intensity of high energy ion beams. The principle experi- ments of this new acceleration concept have been done by the Japan＇s High Energy Accelerator Research Organization （KEK）. In this paper, a Matlab program has been build to simulate the longitude dynamics of the induction synchrotron, based on the param- eters and results of the principle experiments. The simulation results are in accordance with the theoretical analysis and experi- ment results. The causes of the beam loss problems in the principle experiments are analyzed by simulation and some advices for future improvements of induction synchrotron are proposed.
