摘要

根据设计目标的性能参数和结构位置，通过综合迭代法得到电子枪初值；并对比钨与LaB

两种阴极材料的性能，选择合适的阴极材料，利用SOURCES中相关程序对60 kV的太空电子枪进行了仿真，得到色差系数、束斑直径等仿真结果。根据焦距公式得到一级聚焦系统的焦距并进行聚焦系统的仿真，得到焦距、束斑和电子光路等仿真结果。通过分析一级聚焦系统的不足之处，重新设计二级聚焦系统，并由仿真得到极靴孔直径、线圈激励等性能参数和电磁透镜轴上场分布图。最后根据二级聚焦系统仿真结果，得出了符合要求的电子枪参数与电子光学参数。

Abstract

According to the performance parameters and structure position of the design target

the initial value of the gun is obtained by the comprehensive iteration method. Moreover

the performance of tungsten and LaB6 cathode materials was compared

the appropriate cathode materials were selected

and the 60 kV space electron gun was simulated by using the SOURCES related procedures

and the simulation results such as coefficient of chromatic aberration and beam spot diameter were obtained. According to the focal length formula

the focal length of the first-order focusing system is obtained and the simulation results of the focusing system

such as focal length

beam spot and optical path diagram

are obtained. By analyzing the shortcomings of the first stage focusing system

the second stage focusing system is redesigned

and the performance parameters such as pole shoe hole diameter

coil excitation and the distribution map of the electromagnetic lens axis are obtained by simulation. Finally

the parameters of electron gun and electron optics are obtained according to the simulation results of two-stage focusing system.
