| 摘 要： | 电子枪是耦合腔行波管的核心部件之一，枪的电子束参数对行波管工作性能有重要影响。在使用PIC软件设计一S波段耦合腔行波管时，对电子枪进行了数值模拟，构建了行波管的三维整管计算模型，该模型包含电子枪、慢波结构、微波输入输出耦合器等部件，模拟了该S波段行波管整管的大信号注波互作用过程。模拟结果表明：在2.0~2.3GHz工作频带内，该行波管的连续波输出功率达5.9kW，效率为24%。整管模拟为行波管设计提供了依据。

| Abstract: | Electron gun is one of the key components of coupled-cavity traveling-wave tube(TWT).Its electron beam parameters have important influence on TWT performances.As a result,electron gun was firstly simulated when an S-band coupled-cavity TWT was designed using PIC software.Then,the three-dimensional simulationmodel of whole TWT was constructed,which consists of electron gun,slow-wave structure,microwave input and output coupler,etc.Finally,the large signal beam-wave interaction of the whole S-band TWTwas simulated.Results show that the continuous wave output power reaches 5.9 kW and the efficiency reaches 24% in the operating frequency range of 2.0-2.3 GHz.Whole-tube simulation provides reference for TWT design. |
