Thermal management of tungsten leading edges in DIII-D

•Experience with tile alignment, documentation and thermal modeling are important aspects of thermal management in DIII-D.•Various approaches to leading edges and thermal management were investigated for tungsten coated TZM inserts installed for the DIII-D Metal Tile Experiment.•The DIII-D team completed a second W leading edge experiment using the DiMES materials probe on support of ITER.
