Abstract
Varian is carrying out the development of high-power, CW gyrotrons at frequencies ranging from 100-140 GHz.Recent experiments, carried out at a frequency of 110 GHz, resulted in the generation of output powers of 500 kW for 2.5- second pulses and 1 MW for 1 ms pulse durations.1 The output mode of this tube was a whispering-gallery mode, based onthe TE22,2 mode employed in the interaction cavity. Current design activity is aimed at producing a 1 MW CW gyrotron atthe same frequency, but with a gaussian output mode structure. This type of output mode is desirable for low-losstransmission in a corrugated waveguide or mirror transmission line. In addition to the change in output coupling, the cavitymode will be changed to the TE22,6 mode. The higher order cavity mode is consistent with higher power or higherfrequency requirements that will be addressed in subsequent development activities.
