To develop high harmonic terahertz gyrotron, gyrotron with quasi-optical confocal cavity has been studied. Theoretical studies show quasi-optical confocal cavity has good mode selectivity and could be adopted in high harmonic gyrotron. A 400 GHz second harmonic gyrotron with confocal cavity is designed and experimented. In initial experiment, 396GHz second harmonic output with 1.5 kW power is observed.
In this paper, the design of a double-anode magnetron injection gun for a 0.56THz third harmonic gyrotron is presented. Simulation predicts that a high quality electron beam is generated with parallel velocity spread of 2.19%, perpendicular velocity spread of 1.0%, and velocity pitch spread of 3.18% at α=1.5. The variations of velocity spread due to operation parameters are also presented.
