Abstract 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.
