| Abstract: | Electron beam performance parameters of a double-anode magnetron injection gun(MIG) for 8 mm second harmonic gyroklystron amplifier is calculated. According to these parameters, double-anode MIG is designed and optimized by using EGUN simulation. The ratio of perpendicular to parallel velocity is 1.45 and velocity spread is 5.4%. Many factors such as electrode shape, magnetic distribution, beam current, control anode voltage, second anode voltage influenced electron gun performance are discussed. The results show that electron beam performance is sensitive to these factors． |
