TL;DR: A summary of recent DIII-D divertor physics activity and plans for future divertor upgrades can be found in this paper, where the divertor heat flux control by means of D 2 gas puffing and impurity injection were studied separately and in both cases up to a factor of five reduction of the diveror peak heat flux was observed.

TL;DR: In this article, the expanded boundary divertor in Doublet III was analyzed and the authors showed that the divertor density ne(Div) rises with the cube of the main plasma line average density, n e, and the neutral pressure at the exhaust end has a quadratic dependence on n e with divertor plasma temperatures ≲ 15 eV.

TL;DR: In this article, the physics of partially detached divertor plasmas, with divertor heat flux reduction by divertor radiation enhancement using D2 puffing, were studied in two dimensions, and a model of the heat and particle transport was developed that includes conduction, convection, ionization, recombination and flows.
