摘要：

An X-band superradiance relativistic backward wave oscillator(RBWO) was designed by particle simulation applying superradiance mechanism, and the devices experimental study was performed on a compact Tesla pulse source. Space power integration and analysis of radiation microwave time-domain signal indicate that microwave pulses of 1.4 GW peak power, 9.36 GHz central frequency, 500~700 ps pulse width, TE11 radiation mode and 100 Hz repetitive pulse frequency were generated with an electron beam of 350 kV voltage, 4.8 kA current and 3.1 ns pulse width and a guiding magnetic field of 2.2 T. The power transfer efficiency exceeds 80%. The experiment results are consistent with the simulation results. The repetitive subnanosecond GW-level microwave was realised successfully under short electron pulse condition.
