Abstract :
Siliconisation has been performed for a long period of operation as the routine wall coating procedure of TEXTOR-94. The general aim was to study the behaviour of TEXTOR-94 with a medium-Z plasma-facing material and to compare it with that under freshly boronised as well as `carbon dominatedʹ conditions. This contribution focuses on the characteristics of Si-impurity release from the limiters, and the influence of the Si coating on the release of carbon and oxygen impurities with special emphasis on material mixing effects on the plasma-exposed surfaces.
