The results of tests on a Varian 140 GHz CW gyrotron are presented. In initial pulse tests on the tube, an output power of 100  kW was achieved at 28% efficiency in the desired TEU0 031 cavity mode. Under CW operating conditions, the tube achieved an output power level of 75  kW at 31% efficiency. This is the highest CW power level ever obtained at a frequency above 100 GHz in a microwave tube. During CW tests, measurements of the ohmic losses in the interaction circuit were made and the… CONTINUE READING
