A repeatedly operating splitcavity oscillator with hole foilfocused beam

摘要: 设计了一种有孔箔聚焦电子束的高功率分离腔振荡器，并对其进行了理论和数值研究。这种器件采用孔箔聚焦电子束，可以增加重复运行的次数，有效延长导电薄膜的寿命，而且不需要外加磁场聚焦电子束，波束相互作用区短，功率容量大，结构简单，输出信号稳定。还设计了电子束收集极来减小反射电子对器件的影响。对同一器件使用不同电压和电流的电子束，可以得到从50~900MW功率的微波输出。

Abstract: A repeatedly operating splitcavity oscillator with conducting foils with hole on fool for focusing the electronic beam is presented. An equilibrium equation for foilfocused electron beam is deyived, and the collector of electron beam is designed, Which can generate 50MW to 900MW of output power without change parameters of system.
