X波段速调管功率合成输出结构研究(TE01模输出窗设计)

Design of TE_(01) Window for X-Band High Power Klystron

在对X波段高峰值功率微波源迫切需求的牵引下,该文为X波段高峰值功率速调管功率合成输出结构设计了一个工作在9GHz的TE01模输出窗,输出窗相对带宽大于7%,通带内插入驻波比小于1.2。此外,该文还建立了TE01模输出窗窗片稳态温度分布的计算方法。理论分析表明,该输出窗传输50MW的高峰值功率不会由于温升而出现窗片的破裂。

In this paper, an X-band TE01 output window is designed, which is suitable for high power klystron. TE01 window has its uniqueness to avoid voltage breakdown due to its mode pattern and window structure. Center frequency for this window is 9GHz and bandwidth can reach as high as 7% with standing wave ratio below 1.2：1. Theory about heating effect on the designed window has been established, which shows that window cracking due to temperature gap will not occur when high power microwave with its peak value of 50MW, pulse length of 1.5 μ s and repetition rate of 180Hz is passing through.
