摘要
采用高频场软件对输入腔、中间腔和输出腔的高频特性进行冷腔分析。利用3维粒子模拟软件对L波段强流相对论速调管进行整体建模,模拟分析了整管工作情况,并讨论了3维模型中输入、输出耦合结构的引入对结果的影响。模拟参数为:电子束电压500 kV,电流5 kA,微波频率1.3 GHz,输出平均功率600MW,效率约25%。
This paper conducted the simulation study in 3 dimensions. The cold-cavity analysis was performed for input, idler and output cavities by high frequency field software. The whole L-band RKA tube was modeled by three dimensional particlein-cell method, and special attention was put onto the influence of the input and output coupling structures. The optimized parameters in the simulation are as follows： the electron energy is 500 keV, the current is 5 kA, the working frequency is 1.3 GHz, the mean output power is 600 MW and the efficiency is about 25%.
