Recent operating experience with Varian 70 GHz and 140 GHz gyrotrons
Abstract
The design features and initial test results of Varian 70 GHz and 140 GHz CW gyrotrons are presented. The first experimental 140 GHz tube has achieved an output power of 102 kW at 24% efficiency under pulsed conditions in the desired TE sup o sub 031 cavity mode. Further tests aimed at achieving the design goal of 100 kW CW are currently under way. The 70 GHz tube has achieved an output power of 200 kW under pulsed conditions and possesses a wide dynamic range for output power variations.
