利用电子注分析器研究电子枪性能

Investigation of Electron Gun Properties Using Beam Analyzer

本文介绍了电子注分析器系统和电子枪电子光学实验的研究,分别对栅控电子枪和阳控电子枪进行了测试,得到了电子注运动轨迹和电流密度分布,并将阳控电子枪的实验结果与实际设计数据和OPERA计算结果进行比较分析,获得了较好的一致性。结果表明,电子枪的电子光学研究可以验证计算模拟结果,有效地为电子枪的结构设计提供实际参考数据。

This paper presents beam analyzer system and electron optics experiment of electron gun.Grid controlled and anode controlled gun are tested,then beam waist position and current density distribution are obtained.The experimental results for anode controlled gun are in good agreement with the actual design data and calculation results from OPERA.The results show that the research on electron optics could verify the simulation,and offers a practical reference for structural design of electron gun availably.
