ABSTRACT. This paper reports experiments carried out at JET in the high-shape 2.5MA ELMy H-mode scenario to integrate the core plasma performance of ITER with an edge compatible with the metallic plasma facing component. Plasma with different divertor geometry are investigated with significant change in the pedestal density. Neon and nitrogen as a seed impurity are also compared with important difference in the pedestal pressure behaviour.
