【摘要】 在热阴极微波电子枪的研制中,为设计微波腔链与波导的耦合孔,应用Derun Li等提出的“能量方法”进行模拟计算。使用MAFIA计算微波电子枪第3腔与外回路馈电波导之间的耦合度,从而设计连接波导与腔链的耦合孔,使两者之间的耦合度满足需要。该方法的计算结果与实验测量值的差别在10%—30%之间,满足实际加工要求。说明其对于驻波加速腔链与外回路耦合的设计计算是相当有效的。更多还原

【Abstract】 To design the coupler of one kind of thermionic cathode microwave electronic gun, we apply the "energy method", which calculates the coupler factor between the waveguide and cavities of the electronic gun. So we can design the geometry size of the coupling iris. MAFIA code is used. Comparing with the experiment results, the simulating results is in agreement with measurement about 10%—30% deviation. "Energy method" is an efficient and simply method to calculate the coupler factor between cavities and waveguide.更多还原
