Abstract (englisch):

Europe develops and manufactures megawatt-class gyrotrons for electron cyclotron heating and current drive of nuclear fusion experiments. For the gyrotron R&D at Europe, two important fusion experiments are the stellarator Wendelstein W7-X at Greifswald, Germany and the tokamak ITER at Cadarache, France. Considering the 10 MW ECRH system of W7-X, 140 GHz, 1 MW CW (1800 s) gyrotrons were built by European industrial partner THALES, Vélizy-Villacoublay, France (Thales TH1507). The gyrotrons performed reliably during the first experimental campaign of W7-X. Based on that success, an ongoing development targets for a W7-X 140 GHz, 1.5 MW gyrotron upgrade (THALES TH1507U). Already operating is another variant of the W7-X TH1507 gyrotron, it is the dual-frequency 126 GHz / 84 GHz, 1 MW (2 s) gyrotron for the TCV tokamak at SPC, EPFL, Switzerland (THALES TH1510). Considering ITER, the European GYrotron Consortium (EGYC) completed the main development of the European 170 GHz, 1 MW CW gyrotron (THALES TH1509). In parallel, long-term options for a European DEMOnstration power plant are under consideration. It requires the development of gyrotrons with an operating frequency starting from 136 GHz up to, possibly, 240 GHz. ... mehr
