摘　　要：多级降压收集极是提高行波管效率的有效途径,本文在粒子算法的基础上,编写了多注行波管收集极的专用软件,实现了电子收集的三维模拟,计算结果与二维程序进行了比较,并利用该软件设计模拟了一个五注行波管两级降压收集极,对计算结果进行了分析。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.
