Abstract

This report covers four papers presented by the Euratom-CEA Association at the 9th International Conference on Plasma Surface Interaction in Controlled Fusion Devices in May 1990. The first paper describes power deposition to the facing components in Tore Supra. In the presence of the ergodic divertor a broadening of the SOL is seen. Large asymmetries on power deposition on the front face of the limiter cause hot spots at the leading edges. The second paper reports two major effects found in benchmarking the operational regimes of the ergodic divertor; strong changes occur in the ergodised boundary layer but at the same time the central plasma is not directly affected. The third paper analyses the topology of heat load patterns on the plasma facing components, using field line tracing and a derivation of effective heat transport coefficients. The final paper studies the influence of air exposure on graphite implanted by low energy high density deuterium plasma.
