| 摘 要： | 在传统行波管的放大过程中，随着电子纵向群聚的加深，由于空间电荷效应导致的非线性效应，影响了行波管的输出性能。介绍了一种新型的行波管并分析了其作用机理，分析了这种新型行波管慢波系统的结构及其色散特性，讨论了T形齿结构和梯形齿结构慢波系统几何尺寸对工作性能的影响。通过圆极化行波的高频横向电场调制电子束，导致电子束在空间的扭转，使得电子在放大过程中没有经过纵向群聚而处于减速场中，消除了非线性效应，提高了行波管的输出性能。

| Abstract: | In the amplifying process of traditional traveling wave tube(TWT) with longitudinal congregation of electrons,space-charge effect will lead to nonlinear effect affecting output properties of TWT.In this paper a new kind of TWT is introduced and its working principles are analyzed.Structure of the TWT with slow wave system and its dispersion characteristics are analyzed.The affect of apparatus sizes on its working principles is discussed.Electron-beam turns in space whder modulation by the high-frequency transverse electrical field with circularly polarized traveling wave.In the process of amplifying electron beam is locating in the decelerating field without longitudinal congregation so that the nonlinear effect is eliminated.Output properties of TWT are increased. |
