摘　　要：对S波段永磁式全腔提取相对论磁控管进行了理论设计和数值模拟研究,并对其进行了实验研究。通过理论分析初步获取相对论磁控管结构参数,并采用三维电磁仿真软件对模型进行粒子仿真优化,根据引导磁场需求设计永磁磁场产生结构。该永磁式相对论磁控管在500 kV电压输入条件下,输出微波功率1.978 GW,效率49.2%。利用实验室小型脉冲功率驱动源平台开展了初步实验研究。实验中,该永磁式相对论磁控管在脉冲驱动源驱动下获得GW级输出功率,功率转换效率约40%,实验结果与模拟结果吻合得较好。In this paper,an S band all cavity extraction relativistic magnetron with permanent magnet is theoretically designed and numerically simulated,and an experimental investigation is also carried out.The initial structural parameters of the relativistic magnetron are obtained through theoretical analysis,and the model is optimized by particle simulation.The permanent magnetic field generation structure is designed according to the needs of the guiding magnetic field.Simulation results reveal that this permanent magnet relativistic magnetron could generate a microwave power of 1.978 GW corresponding to a power conversion efficiency of 49.2%when the driver voltage is 500 kV.This permanent magnet tube is tested on the high-voltage pulse drive platform.In the experiment,gigawatt class output microwave power was obtained,corresponding to a power conversion efficiency of about 40%.The experimental results are in good agreement with the simulation results.
