Abstract :
Summary form only given. A gyrotron designed to produce 3 MW at 140 GHz has been realized and tested. The cavity is coaxial with a desired operating mode of TE/sub 21, 13/. The coaxial cavity was designed to have peak ohmic heating of 2.9 kW/cm/sup 2/ with low mode competition, and thus a higher electronic efficiency (45%) than the 37% predicted for a hollow cavity with the same mode number. The efficiency calculations were done by a time dependent, multimode simulation.
