摘要
用等效电路法分析了热阴极微波电子枪的功率自洽过程,给出了微波功率、无载耦合度、束流负载、加速腔参数之间的解析关系式和最佳耦合度的计算公式,阐明了无载耦合度与有载耦合度的关系,分析了枪宏脉冲内微波耦合状态的变化过程,并与实验结果进行了对比,对高占空因子热阴极微波电子枪调束实验中微波反射波形发生较大变化的实验现象进行了分析。
The consistent theory of microwave power coupling and the optimism coupling factor are analyzed in detail by equivalent circuit method in this paper. The relationship among the microwave power, coupling factor, beam loading and parameters of the accelerating cavity is presented with analytical formula. The microwave coupling progress during the macropulse of thermionic cathode RF-gun is discussed and the explanation of experimental phenomena such as the deformation of microwave coupling mode is given.
