Abstract

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.
