| 摘 要： | 根据空间电荷波理论,利用微波等效传输线的概念,建立了多间隙耦合腔中注波互作用的小信号计算模型。同时,还基于电子圆盘模型,建立了相应的一维大信号计算模型。依据模型编写了计算机程序进行了计算模拟,结果显示,小信号模型能较好地反映整管的增益频率特性。一维大信号模型能合理地模拟注波互作用的基本物理过程。另外利用电路反馈的理论,分析了多间隙耦合腔的稳定性,并利用奈奎斯特稳定判据给出了耦合腔稳定条件。

| Abstract: | The small signal model of the beam-wave interaction in the multi-gap coupled cavity was developed,calculated and analyzed,based on the space charge theory and the concept of microwave transmission.Besides,the large signal beam-wave interaction model was also proposed on the basis of one-dimension electron disk model.The computer simulated results show that when it comes to gain-frequency characteristics,the small signal model outperforms the large signal model,which better describes the realistic physical situation of the beam wave interaction.In addition,the stability of the coupled cavity was analyzed by means of the circuit feedback,and its stability conditions were determined on the basis of Niguist Stability criteria. |
