| 摘 要： | 采用过模同轴波纹型返波管,其互作用区由2段周期不同的波纹慢波结构组成,利用粒子模拟软件MAGIC进行数值模拟,得到了X波段稳定的3个频率微波输出。粒子模拟的结果为:在强流电子束电压为570 kV,电流为11.4 kA,引导磁场为0.72 T的条件下,获得的3个频率分别为9.575,10.025和10.475GHz,总微波功率为1.0 GW,效率为15.4%。通过对电压的调节,进一步获得了4个频率的微波输出。

| Abstract: | An over-moded coaxial relativistic backward-wave oscillator was presented. Its interaction zone is composed of rippled slow wave structures with two different periods. In the help of the software MAGIC, three stable frequency microwave output was obtained in X-band. The results of the simulation are as follows: when the beam voltage is 570 kV, the beam current is 11.4 kA, the guided magnetic field is 0.72 T, and the output frequencies of the microwave are respectively 9.575, 10.025 and 10.475 GHz. The power level is 1.0 GW and the efficiency is 15.4%. By adjusting voltage, four frequency microwave was obtained. |
