Particle Simulation of Slow-Wave System in Multi-Beam Traveling Wave Tube

Abstract:

A time-dependent particle code has been developed to simulate the motion and changing regularity of particles in multi-beam traveling wave tube. Magnetic focusing and interaction models of multi-beam traveling tube were established, and static magnetic field was calculated. The process of bunching particles by periodic permanent magnetic focusing system and beam-wave interaction was also simulated. The results show that particle simulation can really reflect the motion of particles in multi-beam traveling wave tube, which can provide some references for particle study of traveling wave tube.
