在低磁场下使用慢波结构（SWS）实现高功率微波（HPM）源的高效运行一直是高功率微波研究人员追求的一个有吸引力的目标。本文介绍了一种X波段大尺寸慢波结构高功率微波源在低引导磁场下运行的最新实验结果，其功率和效率均有所提高。该发生器由二极管电压为450 - 900 kV的电子加速器驱动，输出微波功率在0.5 - 3 GW范围内，效率保持在约25%。优化后的磁场在0.5 - 0.75 T范围内，具体数值取决于二极管电压。在不使用超导螺线管系统的情况下，在1秒脉冲串模式下实现了非常稳定的100 Hz重复运行，输出微波功率为1.5 GW。
The efficient operation of high-power microwave (HPM) sources using slow-wave structures (SWSs) in low magnetic field has been an attractive aim pursued by HPM researchers. This paper presents the latest experimental results of an X-band oversized SWS HPM source operating at low guiding magnetic field with both power and efficiency enhancements. Driven by an electron accelerator with diode voltages of 450-900 kV, the generator operated with the output microwave power ranging from 0.5 to 3 GW and the efficiency being kept at about 25%. The optimized magnetic field was in the 0.5-0.75 T range, depending on diode voltages. Without the employment of superconductive-solenoid system, a very stable 100-Hz repetitive operation with 1.5-GW output microwave power was realized in the 1-s-burst mode.
