W波段三次谐波回旋管腔体设计
Design of resonant cavity for W-band, third-harmonic gyrotrons
摘要
采用冷腔分析研究了带有光阑结构的开放式谐振腔中的模式竞争，设计了采用TE61模式工作的W波段三次谐波回旋管谐振腔。PIC粒子模拟结果表明：在不考虑腔壁损耗及电子注能散的情况下，采用注电压45 kV、电流3 A的电子注，可以实现三次谐波单模稳定工作，并获得约20 kW的输出功率，对应工作效率14.8%。
Abstract
The mode competition of an open resonant cavity with iris structure is analyzed by using the cold cavity method. The design of a cavity for a W-band third-harmonic gyrotron operating at the TE61 mode is presented. PIC simulation results show that a single-mode third-harmonic radiation with a power of 20 kW can be expected at a beam voltage of 45 kV and current of 3 A, and the corresponding electron efficiency is 14.8%.
