Paper Abstract

Helically cut antennas with feed waveguide deformations together with two or three matching mirrors are usedfor the efficient conversion of high order helically propagating gyrotron cavity output modes into a free spacefundamental Gaussian beam. The aim of this work is to optimize the shape of the deformations such that theantenna is reasonably short and the conversion efficiency (TE22,6 to TEMoo) remains high.
