Study and Realization of Multistage Depressed Collector CAD Software for Traveling Wave Tubes

摘要

摘要: 该文讨论了行波管多级降压收集极CAD理论模型，在二维轴对称条件下，对网格自动划分技术、二次电子发射模型、空间电荷效应计算方法、外加磁场影响、收集极效率计算方法等进行了深入研究，并在现有模型基础上进行了修改，以获得更好的模拟效果。同时在此基础上，开发了行波管多级降压收集极CAD软件UESTC_MDC，并对该软件的使用进行了简单的介绍。最后根据国外研究发展动向，对我国行波管多级降压收集极CAD软件的发展提出了一些可参考的意见和建议。

Abstract: In this paper, the theoretical model of multistage depressed collector for traveling wave tubes, including the technology of automatic mesh generation, the effects of secondary electrons, space charges, magnetic fields and the method of computation of collectors efficiency, is presented in detail. Based on this theory, a two-dimensional software is developed and is used in the design of symmetrical multistage depressed collectors. Finally, the recent development of the theory is summarized and some referable advices are suggested.
