摘　　要：该文建立了宽带速调管耦合双间隙腔的间隙阻抗矩阵频率特性的模拟计算方法,并运用该方法计箅了一个S波段宽带速调管的重叠模双间隙输出腔的间隙阻抗矩阵和等效间隙阻抗的频率特性.最后将模拟计算结果与冷测数据曲线做比较,两者符合得较好,相对偏离只有10％-15％左右,从而检验了该模拟计算方法的可靠性.A simulation computation method for calculating the impedance matrix of coupling double gap cavity of broadband klystron is developed in this paper. The method is used to calculate the impedance matrix and equivalent gap impedance of the double gap cavity with overlap modes of a practical S band broadband klystron. The calculated results are compared with cold test data. The relative difference between two kinds of data is small, only about 10% to 15%, which is a powerful proof for reliability of the simulation computation method.
