摘要
A dual-resonant reflector is proposed to suppress the radio frequency breakdown and enhance the reflection in a high power relativistic backward wave oscillator. The backward wave is reflected by two reflector cavities step by step, therefore, a high reflectivity is obtained. A preliminary high power microwave generation experiment of backward wave oscillator (BWO) with a general resonant reflector and a dual-resonant reflector was carried out. A microwave with power over 3 GW, frequency 9.6 GHz, efficiency 30%, and pulse width 22 ns was generated. The experiment results show that the efficiency of BWO with a dual-RR is enhanced about 2%-6%.
