Abstract

The operating parameters of the ITER divertor are varied around the partially attached operating point of Refs. [A.S. Kukushkin et al, Berchtesgaden, 1997 A.S. Kukushkin et al, Contributions to Plasma Physics 38 (1998) 20], to obtain an operating window with low heat load, acceptable He pumping and high devertor radiation. Lower heat diffusivities lead to higher heat loads which can be compensated by somewhat lower input power. The divertor geometry is varied: longer domes lead to higher heat loads, whereas the case without dome exhibits poorer helium pumping. Shorter divertor length cases show higher heat load and little change in helium pumping.
