This paper presents a design investigation of the Electron Optical Gun (EOG) for a 42 GHz, 200 kW second harmonic gyrotron operating in the TE_{0, 3} mode. The initial design of MIG is done using established design equations and then optimized through numerical simulations. The different software, such as 2D-Numerical codes EGUN, TRAK and 3D-CST Particle Studio, are used to optimize the design and found good agreement in results obtained from these codes. The sensitivity analysis has also been carried out for the sake of complete design. Furthermore in brief, a design has been done for the un-depressed and Single-Stage Depressed Collector (SDC). In addition, the uneven or uniform beam distribution on collector wall is presented with result comparison of both the collectors. The optimized beam voltage and single-stage depressed collector voltage are 65 kV, 30 kV respectively.

本文介绍了在TE _0、3下运行的42 GHz，200 kW二次谐波回旋管的电子光学枪（EOG）的设计研究。模式。MIG的初始设计使用已建立的设计方程式进行，然后通过数值仿真进行优化。使用不同的软件，例如2D数值代码EGUN，TRAK和3D-CST Particle Studio，可以优化设计并在从这些代码获得的结果中找到很好的一致性。为了进行完整的设计，还进行了灵敏度分析。此外，简而言之，已经为未减压和单级减压收集器（SDC）进行了设计。另外，通过比较两个收集器的结果，得出了收集器壁上光束的不均匀分布或均匀分布。优化的电子束电压和单级降低的集电极电压分别为65 kV和30 kV。
