This paper reports on cold test and high power measurements of the improved, dimple type quasi-optical mode converter for the 118 GHz, 0.5 MW, 210 s TE{sub 22,6} gyrotron oscillator collaboratively developed by CEA Cadarache, CRPP Lausanne, FZK Karlsruhe and Thomson Tubes Electroniques Velizy. For the low power measurements the required rotating TE{sub 22,6} mode was generated in a coaxial cavity using quasioptical techniques. The high power measurements were performed on the gyrotron output beam using an infrared camera. The evaluated mode purity of the linearly polarized fundamental Gaussian output mode is (96 {plus_minus} 1)% in agreement with calculations.
