Abstract :
Based on the nonlinear self-consistent theory of gyrotron traveling wave amplifier (gyro-TWA), the influence of the reflections of the output port with the taper on the beam-wave interaction in the gyro-TWA is studied. The simulation results show that the amplitude and phase of the reflection coefficient varying with the increase of the taper angle, and the interaction length varying have great effect on the beam-wave interaction and the power profile for the 35GHz TE01 gyro-TWA. The saturated power keeps same approximately, but the saturated gain decreases with the increase of the taper angle under same interaction length.
