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

摘要

摘要: 實驗發(fā)現(xiàn)，當(dāng)盒型輸出窗圓波導(dǎo)與兩端矩形波導(dǎo)的中心軸線出現(xiàn)偏離時，在高頻狀態(tài)下，輸出窗存在鬼模振蕩的隱患，引起輸出窗打火，導(dǎo)致窗片炸裂。該文介紹了一種S波段大功率寬帶速調(diào)管輸出窗鬼模振蕩抑制的方法。通過模擬仿真分析和實驗研究，調(diào)整了輸出窗圓波導(dǎo)段的結(jié)構(gòu)，在對帶內(nèi)駐波系數(shù)影響較小的條件下，成功地消除了鬼模振蕩的隱患，確保即使出現(xiàn)波導(dǎo)輕微不對稱的情況，也不會發(fā)生因鬼模振蕩而引起的輸出窗打火現(xiàn)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.
