| 摘 要： | 轴向提取矩形波导TE10模虚阴极振荡器可以不需要模式转换器或弯曲过渡波导而直接通过天线轴向辐射微波，从而使微波源及其辐射系统更加紧凑。粒子模拟结果表明，在400 keV，8.9 kA的束流条件下，轴向提取矩形波导TE10模虚阴极振荡器在2.12 GHz处可以获得功率为500 MW的高功率微波输出，功率效率为14%，频率、模式纯净。这些结果为相同波段同类装置的小型化提供了一条可能的技术途径。

| Abstract: | A virtual cathode oscillator(VCO) with an axially extracted TE_(10) mode of rectangular waveguide is investigated in this paper.It can emit microwaves axially through an antenna without mode converter or transition waveguide,making the system more simple and compact.The PIC simulation is carried out to investigate VCO.Microwave power of 500 MW is obtained with an electron beam of 400 keV and 8.9 kA,which can be obtained experimentally from the TomaChan accelerator in our laboratory.The beam-to-microwave efficiency is 14%.The frequency and mode of the generated microwave are very pure.These results can provide a possible method for building a compact high-power microwave device. |
