Electron Beam Optics System Computer Simulation for MMW TWTs

The basic feature and design method of MMW TWTs electronic optics system are analyzed in this paper. A method of investigation the beam static characteristics is described using Particle-In-Cell (PIC) simulation and electronic optics model integrated electron gun with periodic permanent magnetic focusing system. It is valuable for achieving the goal of "first-pass design success" and the electronic optics system engineering design and optimization.
