摘要: 基于trade-off平衡方程组得到35 GHz双阳极磁控注入式电子枪的初始参数，通过编程对其主要参数进行优化设计，并经由自主研发的PIC粒子模拟软件CHIPIC中的电子枪计算模块对其进行全三维的数值模拟研究，最终获得了具有横纵速度比为1.5，最大速度零散约为5.4%的高性能电子枪，能够很好地满足35 GHz-100 kW回旋振荡管对电子束的要求。

Abstract: We obtained theinitial parameters for the 35 GHz double anode magnetron injection gun based on the trade-off equations, and got the parameters optimized by programming. We did a 3D numerical simulation using the calculation module of the magnetron injection gun of the particle simulation software, CHIPIC, and got the high performance electron gun with a ratio of transverse velocity to longitudinal velocity of 1.5 and a velocity spread of 5.4%. This beam could meet the requirements of the 35 GHz, 100 kW gyrotron oscillation tube. -
