Atlas for the TEXTOR-DED operations

The dynamic ergodic divertor (DED) of TEXTOR is presently under construction [1]. The concept was developed for a spreading the convective heat flux to a large plasma facing surface. The ergodization of the edge will be achieved by 16 perturbation coils placed on the high field side, inside the vessel (see Fig. 1) and covering about 30 % of a tokamak wall. Th
