Effect on antenna structure of high power RF during plasma operation
Abstract
High-power, long-pulse operation on the Tore Supra tokamak results in considerable stress on the plasma-facing components. The ICH antennas must deliver high-power RF (up to 4 MW per antenna) in this environment. The antenna structure is therefore subjected to the power flux resulting from the interaction between RF and the edge plasma. The structure's response during operation is described, as is the condition of the antenna after prolonged use.
