摘要: 根据边界元法建立物理与数学模型，编制了计算磁控注入枪的程序。使用该程序设计和模拟一个工作在35 GHz，70 kV，10 A基波回旋行波管放大器的双阳极磁控注入枪，获得较好的模拟结果。并对电子注在不同工作电压和磁场下的质量进行了分析计算。计算表明，边界元法在分析回旋器件电子光学方面是一种非常有效的方法。Abstract: Physical and mathematical models of the magnetron injection gun(MIG) were constructed, and a code for MIG’s calculation was developed. A double anode magnetron injection gun for gyro-TWT amplifier working at 35 GHz, 70 kV and 10 A was designed and simulated by the progran, and optimized simulation results were obtained. The influence of the beam voltage and magnet field on electron beam performance was studied. The results show that the boundary element method is an effective approach for analysis of electron optics system in gyro-devices.
