• Next , the effects of the electron - beam quality on the characteristics of the vircator are investigated with simulation method . the simulation results show that the front edge of the beam pulse has almost no effect on the saturated microwave output , while good front edges can accelerate the saturation of the virtual cathode oscillation , and beam quality ( except its energy spread ) has almost no effect on microwave frequency , and so on
  结果表明：上凸形束脉冲前沿可使虚阴极振荡器达到饱和振荡的时间缩短但对微波饱和功率基本无影响；束流脉宽应足够大，否则虚阴极振荡器不能达到饱和振荡(对应本文中的模型，束脉宽应大于16ns ) ；能散度的影响不可忽视，当能散度为5时，束波转换效率从单能束时的3 . 8降至1 . 5 ；束流质量(除能散度外)对微波频率基本上没有影响等。
