Proceedings of U.S.-Japan workshop Q86 on plasma-materials interaction/high heat flux data needs for the next step and steady state devices

This workshop was the third in a series carried out as part of the US-Japan Fusion Cooperation Program. The primary objective of this workshop was to complete the assessment of data on graphite that was begun earlier. A second objective was to assemble the data on graphite in such a way as to serve as a basis with which to compare the features of other candidate materials. Finally, an attempt was made to summarize relevant engineering experience to provide guidelines for component design. The talks are grouped into four broad categories: plasma-materials interactions, neutron effects, hight heat flux phenomena, and engineering issues. Working groups for each of these areas discussed the current status and provided summaries of research. The individual papers in this report vary in format. A great deal of the data is preliminary in nature. Some researchers have included formal discussions of their research, but most of the material in this document are reproductions of slides and viewgraphs presented at the meeting with little explanatory text
