TL;DR: In this article, the basic paradigm of electric field shear stabilization has been discussed in the light of the most recent data, and the experimental results with various theories have been compared.

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.
Journal ArticleDOI

West,R. D. Wood,D Wroblewski +63 more
TL;DR: In this paper, a major portion of the DIII-D program includes studies of the L-H transition, of the VH-mode, of particle transport and control and of the power-handling capability of a divertor.
Journal ArticleDOI

M. R. Wade,J.T. Hogan,D.L. Hillis,M.A. Mahdavi,R. Maingi,W. P. West,N.H. Brooks,K. H. Burrell,D. F. Finkenthal,R. J. Groebner,G.L. Jackson,C. Christopher Klepper,G.L. Laughon,M. M. Menon,P.K. Mioduszewski,Diii-D Team +15 more
TL;DR: In this paper, the authors demonstrate significant exhaust of thermal helium in a diverted, H-mode deuterium plasma with a time constant of ∼8-15 energy confinement times.
Journal ArticleDOI
Quantitative comparisons between experimentally measured 2D carbon radiation and Monte Carlo impurity (MCI) code simulations
TL;DR: In this article, the authors compared carbon line emissions and total radiated power distributions from the DIII-D divertor and Scrape-Off Layer (SOL) with those calculated with the Monte Carlo Impurity (MCI) model.
