Mini-Conference on the First Microns of the First Wall

Abstract

Interactions between plasmas and their surrounding materials (plasma-facing components) are of great interest to present and future magnetic fusion experiments, and ITER [ITER Physics Basis Editors, ITER Physics Expert Group Chairs, ITER Joint Central Team, and Physics Integration Unit, Nucl. Fusion 39, 2137 (1999)] in particular. This interest is the result of concerns with the survivability of these materials, as well as the impact of these interactions back on the plasma. These interactions begin on the surface, but can have consequences a few microns into the material. This mini-conference on these “first microns” was designed to bring to the Division of Plasma Physics Meeting experts on these topics who would otherwise not attend. At the same time, the mini-conference was intended to expose the broader fusion community to these issues. The mini-conference covered in three half-day sessions the topics of lithium coatings and surfaces, mixed materials characteristics, and issues associated with graphite.
