摘　　要：为实现行波管总效率的提高,通过试验及模拟仿真等手段对行波管互作用效率及收集极效率的提升进行了分析研究。通过对螺旋线进行螺距非均匀分布及表面覆膜处理实现了互作用效率的提升;通过采用多级压降收集极并在收集极内收出口处设计使用了“挡板结构”,实现了电子注能量回收效率的提升以及对返流现象的抑制,并根据试验及仿真计算结果成功试制出总效率达到40%以上的X波段螺旋线行波管。In order to improve the efficiency of traveling wave tubes(TWTs),researches on the enhancement of conversion efficiency and collector efficiency are carried out through experiments and simulation.Uneven pitch distribution and film coating of helixes are used to improve the conversion efficiency,and multistage depressed collector and baffle structure are used to improve the energy recovery efficiency of electron injection and inhibit electron regurgitation.Based on the researches,X-band helix TWTs with efficiency more than 40%are developed.
