Abstract

Abstract

The phenomena of a high order mode oscillation in a broadband klystron are described in this paper. Some methods are discussed for suppressing parasitical mode oscillation in klystron resonant cavity. One new method is used to eliminate the oscillation in the broadband klystron. The method can make the high order mode frequency change enormously but the fundamental mode frequency alter faintly through adjust the structure of a resonant cavity, thereby the high order mode oscillation is suppressed. An improved design for resonant cavity with Ansoft HFSS code and corresponding experimental approval has been performed. The testing result of the klystron with the improved resonant cavity shows that the high order mode oscillation can effectively be suppressed.
