Abstract

In present quasi-optical gyrotrons the microwave power is coupled out by edge diffraction. Results of cold tests and hot tests show that the output is non-Gaussian. Output couplers have been tested successfully by using a grating reflector which replaces one of the resonator mirrors. This type of coupling produces almost perfect Gaussian output patterns, enabling the use of an additional perfectly reflecting mirror to focus the output microwave beam efficiently into a corrugated HE(11) waveguide.
