Abstract

Edge pressure profiles can be controlled by the DED in limiter H-mode plasmas. However, no operational window could be found so far where the H-mode pedestal is maintained but the ELMs are suppressed. In the 6/2 base mode configuration the edge pedestal is steadily reduced with increasing perturbation together with ELM size until the plasma is finally driven back to L-mode. A density pump-out has not been observed under these conditions where the near field of the DED directs the plasma onto the inner wall along laminar flux tubes. These results emphasize the importance of the magnetic topology for particle transport.
