| 摘 要： | 设计了一个紧凑型L波段相对论返波振荡器(RBWO),利用Karat 2.5维全电磁粒子模拟程序研究了器件内部束-波作用的物理过程。模拟结果表明:在二极管电压700 kV、电子束流10 kA、导引磁场为1.0 T时,能实现L波段2.23 GW高功率微波输出,平均效率约为31.8%。为验证模拟结果,在高阻加速器平台上进行了初步实验:当二极管电压为703 kV、电流10.6 kA、导引磁场为0.8 T时,实验获得了峰值功率1.05 GW、频率1.61 GHz、脉宽38 ns的高功率微波输出,其功率效率为14.4%。

| Abstract: | A compact L-band relativistic backward wave oscillator(RBWO) is investigated with simulation and experimental method.In simulation,the L-band coaxial RBWO,driven by a 700 kV,10 kA electron beam,comes to a nonlinear steady state in 20 ns.High-power microwave(HPM) is generated with an average power of 2.23 GW,a frequency of 1.60 GHz,and power conversion efficiency of 31.8%.In the primary experiment,the measured microwave frequency is 1.61 GHz,with a peak power level of above 1.05 GW,when the diode voltage is ... |
