Suppression of Ghost Mode Oscillation in S Band High Power Broadband Klystron

摘要

摘要: 实验发现，当盒型输出窗圆波导与两端矩形波导的中心轴线出现偏离时，在高频状态下，输出窗存在鬼模振荡的隐患，引起输出窗打火，导致窗片炸裂。该文介绍了一种S波段大功率宽带速调管输出窗鬼模振荡抑制的方法。通过模拟仿真分析和实验研究，调整了输出窗圆波导段的结构，在对带内驻波系数影响较小的条件下，成功地消除了鬼模振荡的隐患，确保即使出现波导轻微不对称的情况，也不会发生因鬼模振荡而引起的输出窗打火现象。

Abstract: It is found by the experiment that the ghost mode oscillation appears in an output window when the centric axes of two section rectangular waveguides and a cylindrical waveguide in the middle are not on the same line. The ghost mode oscillation may result in sparkling and even cracking of the window. In this paper, a method for suppressing the ghost mode oscillation in S band broadband klystron is discussed through the simulation, analysis and experiment for improving the configuration of the cylindrical waveguide in the output window with little effect on the voltage standing wave coefficient in the operating frequency band.
