Inter-ELM heat loads on tungsten leading edge in the KSTAR divertor
A series of leading edge heat load experiments are performed in KSTAR to study power balance and to support a divertor shaping decision on ITER. Tungsten blocks with leading edges of various heights were fabricated, adjusted and mounted to central divertor of KSTAR with extreme care to avoid the intrinsic misalignment caused by engineering limits. The results from IR measurements and COMSOL simulation are consistent with each other and the power discrepancy found at JET does not exist at KSTAR. A simple calculation with geometrical projection can be used to foreseen the heat load on divertor blocks with arbitrary shapes. Therefore, the results present in this paper are valuable for new design of divertor blocks. Keywords: Power handling, Leading edge, PFC shaping
