Outline of Final Research Achievements

Control of the detached divertor plasma and the resultant reduction of the divertor heat load are one of the most critical issues on the fusion DEMO design study. In this study, understanding of the detached divertor plasma has progressed by analysis of the experimental data and development of the divertor simulation code has progressed. Control of the detached divertor plasma and reduction of the divertor heat load by using impurity seeding has been also investigated.
