Abstract :
Summary form only given. A large-signal analysis was used to model nonlinear effects of a multicavity klystron amplifier associated with the growth of the signal wave such as intermodulation distortion. The analysis was developed using 1D nonlinear Eulerian electron beam equations as well a Lagrangian model. The plasma frequency reduction factor was calculated using Rowe approach where the beam is considered as a pencil beam. The cavities are modeled as RLC circuit with a single resonance frequency. From this analysis it was possible to describe the intermodulation distortion generation and suppression.
