Development of advanced gyrotrons


Beyond ITER, a future nuclear fusion demonstration power plant (DEMO) demands gyrotron frequencies above 200 GHz and gyrotron efficiencies of higher than 60 %. The unit power must well exceed 1 MW. Fast frequency tunability in steps of 2-3 GHz (in a few seconds) using broadband or tunable CVD-diamond windows is required. Beside these fundamental… (More)
