| 摘 要： | 用二维全电磁模型粒子模拟的方法对同轴式反射电子甑别微波发生器-同轴式Reditron中的虚阴极振荡现象进行了研究。模拟结果表明:当注入电流超过同轴波导中的空间电荷限制电流时,在同轴波导漂移区将会形成虚阴极振荡。在给定的模拟参数下,获得了窄带的TM01模式K波段的高功率微波输出,峰值瞬时输出功率达8.62GW,效率在7~10%之间。

| Abstract: | The coaxial Reditron (the reflected electron discrimination tube) is investigated by means of the two-and-one half-dimensional fully electromagnetic model's particle-in-cell simulation.The results of simulation indicate that the oscillation of virtual cathode will be formed in coaxial guide when the current above the space-charge-limiting current is injected.For the given simulation's parameters,the highpower,narrow band,TM01 mode's microwave can be generated.The peak value of instantaneous output power is 8.62 GW with efficiency of 7 to 10 percent. |
