我们展示了 Ku 波段过调制切伦科夫型高功率微波振荡器的数值和实验结果。采用工作电压为 740 kV 的脉冲功率加速器产生峰值电流为 9.9 kA 的相对论电子束，并在 0.8 T 的轴向磁场引导下穿过过调制慢波结构。所研究的发生器产生持续时间为 24 ns、中心频率为 13.76 GHz、功率高达 1.1 GW 的微波脉冲，对应于功率 转换效率约15%。 TM01的准单一模式下工作模式控制得很好。
We present the numerical and experimental results of a Ku-band overmoded Cerenkov-type high-power microwave oscillator. A pulsed power accelerator working at a voltage of 740 kV was employed to generate relativistic electron beams with a peak current of 9.9 kA, which were guided through the overmoded slow wave structures by an axial magnetic field of 0.8 T. The investigated generator produced microwave pulse with a duration of 24 ns, at a central frequency of 13.76 GHz, and with power as high as 1.1 GW, corresponding to power conversion efficiency of about 15%. The operating mode was well controlled in quasi-single mode of TM01 .
