Abstract

Abstract

The nonlinear consistent equations were put forward which could describe the beam-wave interaction in relativistic-backward-wave-oscillator(RBWO). The effects of different parameters on the peak superradiant-power of RBWO, such as accelerating voltage, beam current and coupling impedance, were studied and analyzed by solving the beam-wave interaction nonlinear consistent equations numerically. The PIC simulation results indicate that in superradiant regime, the peak superradiant-power increases markedly by linear-modulating diode voltage and current and adopting non-uniform slow-wave structure, because of correspondingly extended resonating-voltage range and improved energy-exchange efficiency of beam and wave.
