Abstract

TEXTOR, a Tokamak primarily devoted to plasmawall interaction studies, has been operated during the last 23 years under a wide variety of discharge conditions. Discharges with Ohmic heating only and with additional ICR heating in the MWrange were produced over an extended range of plasma parameters. Different limiter materials were used Inconel, stainless steel, graphite, TiC coated graphite. The surface of the first wall (liner) consisted either of Inconel or of a carbon layer deposited upon the Inconel. Characteristic features of the discharge have been modified by making use of the modular pump limiter ALTI and by applying a localized perturbation coil for "ergodization" of the magnetic field structure in the boundary. The characteristics of plasmawall interaction under these conditions and their influence on the global performance of the TEXTOR plasma are described and discussed. Use has been made of novel diagnostics specifically developed for edge plasma investigation.
