Abstract :
High power gyrotrons utilize high order TE cavity modes that must be converted to a Gaussian beam that is matched to a corrugated transmission line that supports the HE11 mode for low-loss, efficient transmission to their loads. In the standard configuration, the corrugated waveguide is external to the gyrotron. We report hot-tests results of a novel design that converts the TE mode to the HE11 mode inside the gyrotron.
