Electrodynamic parameters of the double-gap output structure for multiple-beam klystron

Electrodynamic parameters of complicated output RF systems of multiple-beam klystron are under research in this article. The gain-frequency characteristic was obtained, values of operating frequencies, loaded and unloaded Q-factors, R/Q values and interaction coefficients of the double-gap output cavity with matching system and output waveguide were calculated. Dependence of external Q-factor from coupling diaphragm proportions was investigated. The recommendations to improve the parameters of the output multiple-beam system were issued.
