N2 - In ohmic discharges the divertor plasma seems not to be affected by the transition from C to W. Changes occur in H-mode discharges, especially with the W coverage of the poloidal LFS limiters. The reduction of C affected the edge cooling. While the total Prad stayed unchanged W is a weaker radiator in the edge than C. Obviously, especially in additionally heated plasmas, C is an important radiator where it can be partly replaced by boron. In plasmas with low collisionalities the outer divertor in ASDEX Upgrade became hot (up to 50eV).
