Abstract

Measurements of the elemental composition of samples of the vacuum vessel wall surface and of relative impurity influx rates into ATC during high power beam-heated discharges are combined with a computer simulation of the plasma and previous measurements of power balance and scaling laws to give a model of the main plasma-wall interactions in ATC. It is shown that plasma and beam charge exchange neutrals are the primary causes of impurity influx during neutral beam injection.
