| 摘 要： | 根据绝热压缩和角动量守恒理论对55 GHz双阳极磁控式注入枪进行了初始参数的设计，并利用自主研发的三维粒子模拟软件CHIPIC对其进行数值模拟，通过改变阴极半径、电子注电流、阴极磁场等参数来分析其对磁控注入式电子枪输出结果的影响。最终通过优化参数和综合因素的考虑，得到了横纵速度比为1.44、最大速度零散为5.8%的高性能电子束，能够很好满足55 GHz回旋振荡管对电子束的要求。

| Abstract: | The initial design of magnetron injection gun was analyzed based on the theory of the adiabatic compression and conservation of angular momentum. A series of initial parameters of 55 GHz double anode magnetron injection gun were obtained by Matlab programming. Independent research and development of three-dimensional particle simulation software CHIPIC was used to carry out numerical simulation. The obtained simulation data were analyzed and optimized. High-performance electron beam was obtained with a ratio of transverse velocity to axial velocity of 1.44 and a maximum velocity spread of 5.8%. The beam could meet the requirements of 55 GHz gyrotron oscillator tube. |
