This paper presents ERO-TEXTOR simulation calculations of chemical erosion of a carbon limiter exposed to the TEXTOR Scrape-Off-Layer. The spatial distribution of CD-emission near a testlimiter is calculated in dependence on the plasma parameters and on the sticking probability for hydrocarbons hitting the limiter surface. The comparison of D/XB values with experimental data on TEXTOR-94 indicates that eroded hydrocarbons returning to the limiter surface have an extremely low effective sticking. This can be understood in terms of a high re-erosion of the freshly deposited a-C:D layer. The comparison of the radial distribution of the CD- and CII-emission between simulation and experiment shows a good agreement. |
