Nuclear Data Section
Data for surface composition dynamics relevant to erosion processes
An IAEA Nuclear Data Section Coordinated Research Project
OBJECTIVES
This CRP is organized to increase understanding of erosion processes in fusion devices, such as ITER. Plasma constituents, such as ions and electrons interact with the solid wall materials of fusion devices, leading to erosion of wall materials and later re-deposition of those materials. Several different processes can take place in such interactions, such as physical sputtering, reflection, and various chemical reactions. Often, the details of such interactions are not well enough known to understand and predict erosion processes in fusion devices. In many cases even the pathways of eroded materials are not well known.
This CRP will use experimental and theoretical techniques to address these issues, resulting in a better overall understanding of erosion processes and possible methods to mitigate such effects in future fusion devices.
This Coordinated Research Project was strongly recommended by the Atomic and Molecular Data Subcommittee of the International Fusion Research Council (IFRC).
The 1st Research Coordination Meeting (RCM) is scheduled to be held 17-19 October 2007 in Vienna, Austria.
