Abstract

Abstract

It is found by the experiment that the ghost mode oscillation appears in an output window when the centric axes of two section rectangular waveguides and a cylindrical waveguide in the middle are not on the same line. The ghost mode oscillation may result in sparkling and even cracking of the window. In this paper, a method for suppressing the ghost mode oscillation in S band broadband klystron is discussed through the simulation, analysis and experiment for improving the configuration of the cylindrical waveguide in the output window with little effect on the voltage standing wave coefficient in the operating frequency band.
