Experimental study of a 95GHz gyrotron

A 95GHz gyrotron has been developed which has achieved operation of 30.1kW/600s with an inside quasi-optical system. A triode magnetron injection gun, a TE62-mode cavity and a single-stage depress collector are adopted in the design, which predictes a power of 37kW generated from the cavity. The RF power is then changed into gaussian beam by the quasi-optical system with an efficiency of 85%. The design and the experimental results shows good consistency with each other.
