提出了一种具有双腔提取器的类速调管相对论后向波振荡器（RBWO）。与单腔提取器相比，双腔提取器中轴向电场分量E z 的相位变化0°，并且在第二提取腔中出现更大的电场。这种改进的场分布有利于将调制束功率转换成微波功率。细胞内粒子模拟结果表明，当二极管电压为1.2 MV、束流为17.3 kA时，产生功率为10 GW、频率为4.3 GHz的微波，转换效率为48%。
A klystronlike relativistic backward wave oscillator (RBWO) with a dual-cavity extractor is presented. The phase of the axial electric field component E z varies by 0° in the dual-cavity extractor, and a larger electric field appears in the second extraction cavity, in comparison with a single-cavity extractor. Such an improved field distribution is beneficial for converting modulated beam power into microwave power. The particle in cell simulation results reveal that microwaves with power of 10 GW, frequency of 4.3 GHz are generated, and conversion efficiency is 48% when diode voltage is 1.2 MV and beam current 17.3 kA.
