| 摘 要： | 提出由双电子注同轴相对论返波管产生双频的设想，采用2.5维相对论全电磁PIC粒子模拟软件，进行了粒子模拟研究。结果表明，在环形相对论电子注电压625 kV，电流24 kA，引导磁场0.772 T的条件下，器件得到了稳定的高功率双频微波输出。其双频微波频率分别为11.5，12.2 GHz，两频率相差0.7 GHz，平均功率约为1.15 GW，平均功率效率7.7%。另外，还通过改变周期数，进一步获得了三频的微波输出，并对结果进行了讨论。

| Abstract: | The dual-electron beam coaxial relativistic backward wave oscillator(RBWO) was firstly put forward to produce dual frequency microwave output. The properties of the RBWO we investigated with a 2.5-dimensional relativistic fully electromagnetic PIC software. The results show that, for annular relativistic electron beam with voltage of 625 kV, current of 24 kA and guided magnetic field of 0.772 T, the device can produce stable dual-frequency microwave output. The frequencies are 11.5 and 12.2 GHz the average power is about 1.15 GW and the average power efficiency is 7.7%. Three frequency microwave was obtained by changing the cycle number, and the results we discussed． |
