Title: Advanced Divertor Development on NSTX-U

Abstract

Collaboration with PPPL to develope various magnetic configurations on NSTX-U that were about to be experimentally achieved and studied. We also performed SOLPS simulations of the advanced divertor geometries for NSTX-U parameters. The simulations demonstrated the advanced divertor configurations could sustain full detachment without degradation of the core plasma and H-mode transport barrier. In this study, we developed a deeper understanding of the relation between the physics-based metrics and the actual divertor performance. This could be viewed as a basic contribution to the physics of divertors.
