Abstract

A resonator consisting of three successive cavities with different radii is proposed for a step-tunable gyrotron. Different frequencies of the operating mode can be excited in individual cavities by means of changing the beam radius and the strength of the external magnetic field. A resonator for the frequencies 120 GHz, 140 GHz, and 150 GHz, as desired by the JET, is considered for the operating mode as an example. Mode competition in this resonator is investigated theoretically.
