摘要
用模拟计算的方法 ,研究了微脉冲电子枪的束流动力学行为 .基于微脉冲电子枪的工作原理和束流动力学特点 ,用VC ++语言编制了微脉冲电子枪的辅助设计软件———SEEG对微脉冲电子枪中电子的三维运动进行多粒子跟踪模拟 .文中给出了模拟计算的基本原理 ,经过SEEG程序稳定性的测试 ,最后应用SEEG程序模拟了一个微脉冲电子枪的束流运动特性 .
The beam dynamics in micro-pulse electron guns (MPG) is studied using simulation methods in this paper. Based on the working principle of MPGs and the characteristics of its beam dynamics, a multi-particle trace simulation about the three-dimensional movement of the electrons in a MPG cavity is given by a program SEEG (Secondary Electron Emission Gun) written in VC++. The paper includes the principles of simulation and the stability tests of the program SEEG. A specific MPG is simulated using the program SEEG and the simulated beam dynamic results are given.
