The German PMW project and the European EGYC consortium are driving gyrotron developments for the two major plasma fusion experiments in Europe using ECRH, Wendelstein W7-X at Greifswald and the international ITER at Cadarache. 1 MW CW, 140 GHz conventional cavity gyrotrons have been developed and are being delivered to W7-X whereas advanced 2 MW CW, 170 GHz coaxial-cavity gyrotron technology has been tested for ITER. Additionally, an 1 MW, 170 GHz conventional cavity design is under development for ITER. Furthermore, research work on gyrotron concepts for future fusion experiments, focusing on frequency-step tunable gyrotrons and multi-MW coaxial-type gyrotrons is ongoing at Europe, in particular at KIT. This paper is reporting some of the important results and the ongoing research work.
