Abstract :
This paper shows recent measurements on a newly designed mode generator for cold tests of the quasi-optical mode converter system of step-tunable gyrotrons at FZK. This mode generator was designed to excite more than one mode by choosing a broadband quasi-optical method. 4 modes at different frequencies have been found and assigned to their mode numbers. The used measurement setup and the measured mode pattern are shown.
