Abstract

Abstract

In this paper, based on a small-signal theory, an analytical expression for the harmonic contents in the prebunched electron beam in a multicavity gyroklystron is obtained. As an example, the dependence of the harmonic contents in three-cavity gyroklystron amplifier on the prebunched parameters is numerically calculated. The results show that the second harmonic content is much smaller than the fundamental harmonic content and the undulation of the second harmonic content depended on the second cavity prebunched parameters is greater than the fundamental one, and the amplitude of the second harmonics in the electron beam current density as functions of the bunching parameters is proportional to the field amplitude in the second cavity and relate with the electron phase shift resulting from the first drift region and the effect of input cavity Q in a certain range on the harmonic content is little or nothing.
