摘要
本文利用CST软件中的粒子工作室对采用卷绕双梳齿慢波结构的圆极化行波管中的注-波互作用情况进行了粒子模拟研究,观察了电子束的运动情况,同时得到了电压、电流、磁场和输入功率四个重要电气参数对输出功率的影响。研究结果为圆极化行波管的设计奠定了理论基础。
In this paper,the phenomena of beam-wave interaction in TWT with twisted twin comb slow-wave structure are investigated by particle-in-cell code in CST Particle Studio.The pictures of the track of electron beam along the z-axis are observed.Then,the output power,affected by four important electrical parameters including voltage,current,magnetic field and input power,is discussed.The results can be used to design the circularly polarized traveling-wave tube.
