Influence of the Output Electrical Parameters on Multistage Depressed Collector Characteristics in a Coupled Cavity TWT

摘要

Using a depressed collector to collect the residual energy of the electron beam is an important way to improve the total efficiency of traveling wave tube (TWT). In this article, the influence of the output electrical parameters on the characteristics of a three-stage depressed collector in a Coupled Cavity TWT is discussed by analyzing the deviation angle σ(α), which shows that a relatively high electronic efficiency can be reached with relatively uniform electron beam distribution.
