%X In this paper, the beam-wave interaction of a Ka-band complex cavity gyrotron with gradual transition is studied according to a particle in cell simulation program. The effect of the cavity dimension, electron beam parameter and operating magnetic field on the electron efficiency is analyzed. The stability of the working mode is discussed. The results show that an electron efficiency of more than 60% and good stability is predicted for the complex cavity gyrotron with appropriate working parameters when driven by a 70kV, 17A electron beam with a velocity ratio of 1.5.
