摘要：

Better understanding the processes of wall erosion and deposition remains an important issue also for future devices. The three-dimensional Monte-Carlo code ERO-TEXTOR has been developed in order to simulate plasma wall interaction and transport of eroded particles in the vicinity of wall components and to allow comparisons with experimental observations, This paper presents quantitative modelling of local transport and deposition of (CH4)-C-13 which was injected into the edge plasma of TEXTOR-94. In addition, chemical erosion at a graphite limiter in TEXTOR is simulated. Especially, the observed CD photon emission will be compared with measurements. Finally, first results of the modelling of erosion and deposition at an ITER-like divertor target plate are presented. (C) 2001 Elsevier Science B.V. All rights reserved.
