更好地理解壁侵蚀和沉积的过程仍然是未来设备的一个重要问题。三维蒙特-卡罗程序ERO-TEXTOR已经开发，以模拟等离子体壁的相互作用和附近的壁部件的侵蚀粒子的传输，并允许与实验观察比较。本文给出了注入TEXTOR-94边缘等离子体的13 CH 4的局部输运和沉积的定量模型。此外，在TEXTOR石墨限制器的化学侵蚀进行了模拟。特别是，观察到的CD光子发射将与测量进行比较。最后，在ITER的偏滤器靶板的侵蚀和沉积建模的第一个结果。
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 of13CH4which 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.
