摘要
运用全电磁的相对论的２．５维粒子模拟程序ＭＡＧＩＣ模拟分析了３ｃｍ相对论返波管中注－波互作用的非线性过程，得到了器件微波输出功率，效率，工作频率等参量，模拟结果与实验数据较好地一致。对电子注特性参数，慢波结构尺寸，引导磁场进行了优化，获得了器件最佳化运行的工作参数。
A two and one half dimensional electromagnetic relativistic particle in cell simulation code has been used to investigate the nonlinear beam wave interaction and other optimization issues of a 3cm relativistic backward wave oscillator in the paper. The simulation results such as microwave generating efficiency, peak power and frequency are reasonable agreement with experiment data. The dependence of the power on electron beam voltage, eletron beam current, slow wave structure geometry and magnetic guide field were simulated, optimum conditions for the device have been obtained.
