摘要
运用超辐射机理,通过粒子模拟设计了X波段超辐射相对论返波管,并在小型Tesla脉冲源平台上开展了实验研究。通过空间功率积分和直接对辐射微波时域波形的分析得到实验结果:在束压350 kV、束流4.8 kA、脉宽3.1 ns、引导磁场2.2 T条件下,产生的微波辐射功率1.4 GW,中心频率9.36 GHz,脉宽500~700 ps,辐射模式为TE11,能在重复频率100 Hz下稳定运行。功率转换效率超过80%。实验结果与粒子模拟结果比较吻合,成功实现了在短脉冲条件下产生重复频率、亚纳秒脉宽、GW级微波辐射。
Abstract
An X-band superradiance relativistic backward wave oscillator(RBWO) was designed by particle simulation applying superradiance mechanism,and the devices experimental study was performed on a compact Tesla pulse source. Space power integration and analysis of radiation microwave time-domain signal indicate that microwave pulses of 1.4 GW peak power,9.36 GHz central frequency,500~700 ps pulse width,TE11 radiation mode and 100 Hz repetitive pulse frequency were generated with an electron beam of 350 kV voltage,4.8 kA current and 3.1 ns pulse width and a guiding magnetic field of 2.2 T. The power transfer efficiency exceeds 80%. The experiment results are consistent with the simulation results. The repetitive subnanosecond GW-level microwave was realised successfully under short electron pulse condition.
