摘　　要：提出了以边界元法作为理论基础,分析磁控注入枪问题,推导出用边界元法计算这类问题的基本理论方程。并根据整管要求,设计了单阳极磁控注入枪。利用Fortran语言编制了一个模拟计算磁控注入枪的程序,利用计算机辅助设计,给出了电极形状、电子轨迹和电子注参量。理论分析和实际计算结果表明,利用边界元方法分析磁控注入枪是一种有效的方法,具有很好的优点,这为分析电子光学系统提供了一条有效途径。A modified boundary element method （BEM） was presented for analysis of magnetron injection gun （MIG）. The BEM equations were derived. A single anode MIG was designed and calculated according to the requirements of gyrotron. A set of simulation and computation code has been developed. The electrode shape, electron trajectory and electron beam parameters are also given with the computer aided design. By theoretical analyzing and calculating actual examples, it is proven that the BEM is a more effective approach for analysis of MIG system, and can provide an effective approach to analyze electron optics system.
