摘　　要：该文建立了分布作用速调管(EIK)注波互作用模拟的大信号计算模型。该模型基于1维电子圆盘模型,考虑了电子圆盘间的空间电荷力。在电子与高频场互作用计算中采用双间隙耦合腔等效电路方法,并在间隙阻抗矩阵的计算中考虑了耦合腔中每个间隙电子电导的影响。依据该模型编写了计算程序,并与MAGIC3D仿真结果进行了比较验证,结果相符合。该计算模型可以扩展到三间隙乃至更多间隙谐振腔的分布作用速调管注波互作用的大信号计算模拟中。A large signal computation model of the beam-wave interaction in the External Interaction Klystron（EIK） is presented.This mode bases on the one dimensional electron disk model with considering the space charge force between the electrons.The equivalent circuit of the double-gap coupled cavity is used in the calculation of the interaction between electrons and gap field,and the electron conductivity in each gap of the coupled cavity is taken into account.The simulation code has been compiled based on this model and it shows good agreement with the simulation results by the Particle-In-Cell（PIC） code,MAGIC3D.This model can be used in the large signal computer simulation of the beam-wave interaction in the three or more gaps coupled cavity in the EIK.
