| 摘 要： | 该文利用基于绝热压缩原理和角动量守恒理论的解析方程组，在对电子枪相关参量分析的基础上，研究一种阴极采用鼻状辅助聚焦极的单阳极磁控注入电子枪。通过电子光学软件EGUN-226对电子枪结构进行优化设计，比较分析了不同横纵速度比对电子注轴向速度零散的影响。结果表明这种结构的电子枪可以适应比较大的电流应用。

| Abstract: | According to a set of analytic equations based on adiabatic compression theory and angular momentum conservation, a single-anode Magnetron Injection Gun(MIG) with a nose-shape accessorial focus pole is studied in this paper. The parameters of the single-anode MIG are optimized through computer simulation with an electron trajectory code (EGUN226). The effect of the ratio of transverse velocity and longitudinal velocity  on axial velocity spread is analyzed, which shows that a high-quality electron beam with large  and low axial velocity spread can be realized for large current application. |
