Remote-Steering Antennas for 140 GHz Electron Cyclotron Heating of the Stellarator W7-X

EPJ Web of Conferences, 2017
For electron cyclotron resonance heating of the stellarator W7-X at IPP Greifswald, a 140 GHz/10 MW cw millimeter wave system has been built. Two out of 12 launchers will employ a remote-steering design. This paper describes the overall design of the two
