Modeling of an inductive output tube with the MAGIC simulation code

Abstract

We describe the simulation of an inductive output tube (IOT) using the particle-in-cell code MAGIC. Simulations were performed to analyze three basic processes in an IOT: formation of bunched electrons beams from a gridded electron gun, interaction between bunched beams and rf field in a resonator, and spent beam collection with a multi-stage depressed collector. There is excellent agreement between simulation results and experimental data.
