计算了8 mm二次谐波回旋速调管双阳极电子枪的设计参数,根据这些参数,采用EGUN软件进行模拟和优化,设计出了一只双阳极磁控注入电子枪,该枪的电子束纵横速度比为1.45,速度零散为5.4%,并讨论了电极形状、磁场分布、电流、控制极电压和第二阳极电压对电子注性能的影响,结果发现电子注对这些影响因子非常敏感,设计中应对它们进行充分优化.

Electron beam performance parameters of a double-anode magnetron injection gun(MIG) for 8 mm second harmonic gyroklystron amplifier was calculated. According to these parameters, double-anode MIG was designed and optimized 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 influencing electron gun performance were discussed. The results show that electron beam performance is sensitive to these factors.
