R. Maingi,M.A. Mahdavi,T.C. Jernigan,R.J. La Haye,A.W. Hyatt,Larry R. Baylor,Dennis Whyte,M. R. Wade,T.W. Petrie,J.W. Cuthbertson,A.W. Leonard,Masakatsu Murakami,R. T. Snider,R.D. Stambaugh,J.G. Watkins,W.P. West,R. D. Wood +16 more
TL;DR: In this paper, a series of experiments was conducted on the DIII-D tokamak to investigate the physical processes which limit density in high confinement mode (H-mode) discharges.
Journal ArticleDOI

TL;DR: In this paper, a regime of very high confinement (VH-mode) has been observed in neutral beam-heated deuterium discharges in the DIII-D tokamak with thermal energy confinement times up to [approx]3.
Journal ArticleDOI
Fast reciprocating Langmuir probe for the DIII-D divertor
J.G. Watkins,J. Hunter,B. Tafoya,M. Ulrickson,R. D. Watson,R.A. Moyer,J. W. Cuthbertson,G. Gunner,R. Lehmer,P. Luong,D. N. Hill,M. Mascaro,J. I. Robinson,R. T. Snider,R.D. Stambaugh +14 more
TL;DR: In this paper, a reciprocating Langmuir probe was used to measure density and temperature profiles, ion flow, and potential fluctuation levels from the lower divertor floor up to the X point on the DIII-D Tokamak.
