Abstract

Abstract

The mode competition of an open resonant cavity with iris structure is analyzed by using the cold cavity method. The design of a cavity for a W-band third-harmonic gyrotron operating at the TE61 mode is presented. PIC simulation results show that a single-mode third-harmonic radiation with a power of 20 kW can be expected at a beam voltage of 45 kV and current of 3 A, and the corresponding electron efficiency is 14.8%.
