Locked modes in DIII-D and a method for prevention of the low density mode
J. T. Scoville,R.J. La Haye,A.G. Kellman,T.H. Osborne,R.D. Stambaugh,E. J. Strait,T. S. Taylor +6 more
TL;DR: In this paper, a simple theoretical model of the nonlinear stability of a tearing mode under the effect of externally applied resonant field perturbations yields a critical island width for the onset of a locked mode.
Journal ArticleDOI

TL;DR: In this paper, the L-mode to H-mode transition in the DIII-D tokamak is associated with the sudden reduction in anomalous, fluctuation-connected transport across the outer midplane of the plasma.
Journal ArticleDOI
Mitigation of tokamak disruptions using high-pressure gas injection.
Dennis Whyte,T.C. Jernigan,David Humphreys,A.W. Hyatt,C.J. Lasnier,P. B. Parks,Todd Evans,Marshall N. Rosenbluth,P. L. Taylor,A.G. Kellman,D. S. Gray,E. M. Hollmann,S.K. Combs +12 more
TL;DR: High-pressure gas-jet injection of neon and argon is shown to be a simple and robust method to mitigate the deleterious effects of disruptions on the DIII-D tokamak.
Journal ArticleDOI
Stationary high-performance discharges in the DIII-D tokamak
T.C. Luce,M. R. Wade,J.R. Ferron,A.W. Hyatt,A.G. Kellman,J. E. Kinsey,R.J. La Haye,C.J. Lasnier,M. Murakami,P. A. Politzer,J. T. Scoville +10 more
TL;DR: In this article, the DIII-D tokamak was shown to achieve stable operation in the presence of sawteeth and fishbones up to the estimated no-wall β limit.
Journal ArticleDOI
Disruption mitigation studies in DIII-D
P. L. Taylor,A.G. Kellman,T.E. Evans,D. S. Gray,David Humphreys,A.W. Hyatt,T.C. Jernigan,R. L. Lee,J.A. Leuer,S. C. Luckhardt,P. B. Parks,M.J. Schaffer,Dennis Whyte,J. Zhang +13 more
TL;DR: In this article, a simulation of the DIII-D tokamak has been carried out to study the discharge behavior, thermal loads, halo currents, and runaway electrons.
