摘　　要：集合准光腔型虚阴极振荡器和同轴虚阴极振荡器的优点,设计了一种新型的准光腔同轴虚阴极振荡器。采用自由电磁振荡理论分析了3反射镜准光学谐振腔中的场分布,并用2.5维全电磁PIC程序对该器件进行了粒子模拟。在输入电压为600 kV,二极管电流为50 kA的条件下,得到主频为7.0 GHz,峰值功率超过6 GW的功率输出,其平均功率达2.5 GW,平均束波转换效率为8.3%。A coaxial vircator with a new kind of quasi-optical resonator was presented. The 3-mirror cavity＇s field distribution shows that the maximum field in the resonator is located in the cavity＇s center, which can greatly enhance the beam-wave in- teraction efficiency. PIC simulation of this vircator was made using the MAGIC code. When the input voltage was 600 kV, the current of the diode was 50 kA and a microwave pulse output power with a dominant frequency of 7.0 GHz, a peak power of 6 GW was obtained. The average power was 2.5 GW and its officiency was about 8.3%.
