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 splitcavity oscillator with conducting foils with hole on fool for focusing the electronic beam is presented. An equilibrium equation for foilfocused 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.
