摘要
利用MAFIA软件分别对休斯型耦合腔慢波结构进行了由冷腔到热腔的计算机模拟,并将冷腔模拟结果分别与理论计算结果和实验测试结果进行比较,发现模拟结果更加接近实验值,色散特性的平均误差在0.02%左右,耦合阻抗的平均误差在5%左右,基本满足设计要求;由冷腔模拟结果导入MAFIA三维粒子模拟模块中进行注-波互作用模拟,对其工作机理进行了定性分析.
Abstract
The computer simulation from cold cavity to hot cavity of Hughes coupled cavity slow-wave structure is depicted used by MAFIA. Cold cavity simulation result is compared with theoretical and experimental ones. The average error of dispersion is 0.02% and the average error of interaction impedance is 5%. So the simulation result is more consistent with experiment result than theoretical one. It may satisfy design precision requirement. Loaded in three dimension particle-in-cell module in cold cavity simulation, the beam-wave interaction simulation is done using by MAFIA software. The mechanism of beam-wave interaction is qualitatively analyzed by software simulation.
