Design of a Ka Band 35 kW CW Low-Voltage Harmonic Gyrotron
ABSTRACT In this paper, a continuous wave (CW) low-voltage second harmonic gyrotron with the conventional cavity has been preliminarily
designed and evaluated with self-consistent nonlinear simulation code and the particle-in-cell code CHIPIC. The simulation
results of the two codes are shown to be in agreement basically. The 35kW CW output power of the designed harmonic gyrotron
driven by a 25kV 5.0A electron beam from a magnetron injection gun (MIG) is obtained. The maximum output power and the electronic
efficiency of the gyrotron is about 35kW and 30% respectively.
