Abstract

Plasma induced erosion at the limiters and divertor plates will limit their lifetime and also represents a critical source of impurities. However, there are hardly any quantitative measurements of the plasma induced erosion at limiters and of the possible redeposition of the eroded material. In order to obtain such quantitative data a limiter-like carbon probe has been exposed in the TEXTOR tokamak. The measured marker erosion and redeposition of marker materials are compared with calculated values obtained with the computer simulation program ERO.
