Abstract
Based on the nonlinear selfconsistent theory of gyrotron traveling wave amplifier gyroTWA the influence of the reflections of the output port with the taper on the beamwave interaction in the gyroTWA is studied The simulation results show that the reflections have great effects on the TE01 mode gyroTWA operating at the fundamental The influence of the taper angle and the interaction length on the beamwave interaction and the power profile is discussed and the corresponding physical mechanism is analyzed The saturated output power keeps same approximately with the increase of the taper angle in the presence of reflection while the saturated gain decreases obviously
