Abstract
Gyrotron traveling wave amplifier is a very important high power millimeter wave source for radar applications. By studying the absolute instability, the gyrotron backward wave oscillation and the interaction between the electron beam and wave, the stability of amplifier and the suppression of spurious oscillations are discussed. The simulation results of W-band TE01 gyrotron traveling wave amplifier are given. The PIC simulation results show that this amplifier can generate 250kW at 94GHz with 28% efficiency and 50dB gain and 5% bandwidth at 100kV,10A electron beam input.
