Abstract

Currently, a new multi-frequency ECRH system is under construction at the ASDEX Upgrade Tokamak experiment. This system employs, for the first time in a fusion device, multi-frequency gyrotrons, step-tunable in the range 105-140 GHz. The system includes fast steerable launchers at the front end that will allow for very localized feedback controlled power deposition in the plasma.
