Abstract :
A systematic study on Ka band low-voltage third-harmonic gyrotron is presented in this paper. Two types of complex cavity structures with gradual and abrupt transitions are employed in the gyrotrons. A nonlinear theoretical investigation and numerical simulation for interaction between electron beam and RF fields in complex cavities are given. A diode magnetron injection electron gun utilized in the gyrotrons is simulated numerically. The Ka band third harmonic complex cavity gyrotrons with a permanent magnet system are designed and constructed. The experiments of these gyrotrons are in progress.
