Mingming Pan, LV Guo-qiang, Yang Jun, Xie Song-ting

Abstract

Multistage depressed collectors are used in traveling wave tubes to enhance the overall effi- ciency of the device.Very dedicated procedures for multi-beam TWT collector were developed on the base of Particle In Cell algorithm.Compared to the result of TAU,the errors of the PIC simulation results are very little.A two stages depressed collector of a five beams TWT has been designed and simulated using the software,and the results were analyzed.It shows that the software satisfies the precision needs.
