  1. 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

    結果表明:上凸形束脈沖前沿可使虛陰極振蕩器達到飽和振蕩的時間縮短但對微波飽和功率基本無影響;束流脈寬應足夠大,否則虛陰極振蕩器不能達到飽和振蕩(對應本文中的模型,束脈寬應大於16ns ) ;能散度的影響不可忽視,當能散度為5時,束波轉換效率從單能束時的3 . 8降至1 . 5 ;束流質量(除能散度外)對微波頻率基本上沒有影響等。
