Edge Physics and Plasma-Wall Interactions / Proceedings of the Ninth Carolus Magnus Summer School on Plasma and Fusion Energy Physics
An overview of erosion and deposition processes in fusion machines is presented. The underlying physical and chemical mechanisms are explained. The impact of erosion and deposition on wall lifetime and tritium retention, which define the availability of future fusion machines such as ITER, is discussed. Also, examples of erosion and deposition observed in present fusion experiments are presented.
