摘要：
A second-harmonic gyrotron intended as a compact lightweight source has been designed. 99-GHz gyrotron is driven by a 51-kV 11.8-A (v(perpendicular to)/v(z) = 1.32, Delta v(z)/v(z) = 3%) electron beam from a magnetron injection gun and employs a low-loss TE021/TE031 complex cavity for mode control. A pulse output power of 156kW is obtained with cryogen-five superconducting magnet for the gvrotron, magnetic field 1.67T with operating frequency 94GHz, corresponding to an efficiency of 26%.
