摘　　要：为了对扩展互作用振荡器(EIO)进行更为高效研究与设计,提出了一种非线性理论与数值模拟相结合的方法对其进行分析,编制了基于一维电子圆盘模型的数值计算程序,并结合MAGIC模拟结果对其准确性进行了讨论。非线性模拟中,35GHz EIO输出功率为125W,频率为35.01GHz,对应的MAGIC模拟结果分别为100W,35.11GHz;110GHz EIO输出功率为220W,频率为107.9GHz,对应的MAGIC模拟结果分别为190W,107.93GHz。非线性方法使得模拟速度有了很大的提高,单次计算时间小于5min,并且所得数据与传统软件模拟得到的特性曲线相比变化趋势一致、数值上也较为接近。A new numerical nonlinear theory based on 1Delectronic-discs model for an extended interaction oscillator（EIO）is developed in this paper.Combining MAGIC simulation,the cold cavity and hot cavity features of EIO are tested.35GHz EIO could generate 125Won 35.01GHz in nonlinear simulation and 100Won 35.11GHz in MAGIC simulation.110GHz EIO could generate 220Won 107.9GHz in nonlinear simulation and 190Won 107.93GHz in MAGIC simulation.The nonlinear theory approach has a significant advantage of quick calculation that each calculation time is less than 5minutes,and it could get similar results with the MAGIC simulation.
