摘要
阐述了带有反射腔的相对论返波管的初步实验研究进展。反射腔是一段不规则的圆波导 ,在相对论返波管中起到截止颈的作用。初步实验的结果为 :外加磁场 Bz=0 .7T时 ,输出微波功率为 1 70 MW,微波频率 8.874 GHz,脉宽为 1 0 ns;外加磁场 Bz=1 .7T时 ,微波功率为 370 MW,频率与脉宽不变 ;根据辐射场功率密度分布判定传输模式为 TM0 1 模。结果表明
Experimental studies of relativistic backward wave oscillator(BWO) with a resonant reflector are presented. The resonant reflector is a circular wave guide with longitudinal irregularity. The device emits TM 01 microwave at 8.874GHz. The power of BWO is about 170MW at applied magnetic field B z =0.7T, and 370MW at B z =1.7T, both with microwave pulse duration of 10 ns. Experimental results show that BWO with resonant reflector works well at low applied magnetic field, and primary experimental studies will be the foundation of further research work.
