摘　　要：首先对强流相对论电子束在聚焦系统中的传输特性进行了理论分析,给出了束流参数与周期引导磁场峰值大小的关系,然后通过粒子仿真验证了理论分析的正确性,并得到了在一定的电压和通道半径条件下,周期永磁聚焦(PPM)系统能传输的电子束的最大电流。文章为强流相对论电子束周期永磁聚焦系统的设计提供了一定的参考。In this paper,the transmission characteristics of the intense relativistic electron beam in the focusing system are analyzed theoretically firstly,it presents the relationship between the beam parameters and the peak value of the periodic magnetic field,the correctness of which is verified by the particle simulation then.And the maximum current of the electron beam that can be conveyed in the periodic PM focusing system under fixed voltage and channel radius conditions is obtained.It provides a reference for the design of intense relativistic electron beam periodic PM system.
