| 摘 要： | 利用三维电磁场与粒子模拟软件对Ka波段带状注相对论速调管放大器进行了分析设计和模拟计算。通过对谐振腔本征模的计算确定了腔体的冷腔高频特性,采用三维粒子模拟软件(PIC)模拟分析速调管各腔及整管的束波互作用过程。模拟结果表明:在带状电子注电压500kV、束流1kA、宽高比40∶1,注入微波功率1.94kW和均匀聚焦磁场0.8T的条件下,获得的输出微波功率达到142MW,频率40GHz,效率28.4%,增益约48.6dB。

| Abstract: | The high frequency characteristics and beam-wave interaction system with four cavities in the Ka-band sheet beam relativistic klystron amplifier were simulated with three-dimension electromagnetic codes. The simulation results show that for a 500 kV, 1 kA, 40∶1 aspect ratio sheet beam and 1.94 kW input power with 0.8 T leading magnetic field, the sheet beam klystron is capable of generating an output power higher than 142 MW at 40 GHz with a gain of 48.6 dB and a maximum efficiency of 28.4% at a frequency of 40 GHz. |
