Design of the resonator in a 110-GHz Gyrotron

Abstract

On the basis of electron cyclotron resonance maser theory and generalized transmission line theory, we compiled programs to analyze the resonant cavity in a 110 GHz gyrotron. By calculating and studying different gradual-varying and line-joint resonant cavities, we designed a gradually tapered resonator for a 110 GHz Gyrotron, which is good at suppressing the parasitic modes, improving the purity of the operating mode and the efficiency of the beam-wave interaction.
