Abstract

Abstract

A new kind of microwave cavity-strongly coupling two-gap cavities, which can be used in broadband multi-beam klystrons that work in lower frequency band, is designed in this paper. The important parameters of the cavity are calculated with ISFEL3D, a reliable program for solving three dimension electric-magnetic field problems, and the characteristics of this kind of cavity are analyzed carefully. It is showed that strongly coupling two-gap cavities have some prominent virtues, such as higher characteristic resistance and smaller volume when they work in tt mode. Besides, the frequency interval of n mode and 2tt mode is much wider. Furthermore, two kinds of concentrated element equivalent circuits are used in this paper to prove the calculated data and conclusions, meanwhile the precision of two equivalent circuits is discussed.
