Status of divertor experiments

Shimada, Michiya

This is a review article on divertor research: present status and issues. In light of importance of divertor research, divertor diagnositics have been significantly developed, and their data have been compared with transport code calculations and divertor database has been accumulated, which has enabled quantitative discussion on thermal and particle transport, radiative cooling and impurity source. However, inter-machine database has not been archived yet. Inter-machine comparison would improve the estimation of divertor characteristics in future devices.
