Enhanced confinement and stability in DIII-D discharges with reversed magnetic shear.
E. J. Strait,L. L. Lao,Michael E. Mauel,B. W. Rice,T. S. Taylor,Keith H. Burrell,Ming-Sheng Chu,E. A. Lazarus,T.H. Osborne,S. J. Thompson,A. D. Turnbull +10 more
TL;DR: Values of normalized beta, up to 4 ({percent}-{ital m}-T/MA), energy confinement are a factor of 3 better than {ital L} mode, and at least 50% of the noninductive plasma current in this regime demonstrates compatibility with requirements for a steady-state high-beta tokamak power plant.
Journal ArticleDOI
Control of the Vertical Instability in Tokamaks
TL;DR: In this article, the problem of control of the vertical instability of a massless filamentary plasma with finite resistivity included for the shell and active control coil is studied for a DIII-D tokamak.
Journal ArticleDOI
Low voltage Ohmic and electron cyclotron heating assisted startup in DIII-D
TL;DR: In this paper, a low voltage Ohmic startup at E = 0.3 V/m with |B⊥| > 50 G over most of the vessel cross-section has been demonstrated.
Journal ArticleDOI
Chapter 8: Plasma operation and control
Y. Gribov,David A. Humphreys,K. Kajiwara,E. A. Lazarus,J. B. Lister,T. Ozeki,A. Portone,M. Shimada,A. C. C. Sips,J. C. Wesley +9 more
TL;DR: Although the physics basis of plasma operation and control is similar in ITER and present tokamaks, there is a principal qualitative difference and significant progress has been achieved in the plasma performance control during the last few years.
Journal ArticleDOI
Direct Observation of the Resistive Wall Mode in a Tokamak and Its Interaction with Plasma Rotation
Am Garofalo,A. D. Turnbull,Max E Austin,J.M. Bialek,Ming-Sheng Chu,K. J. Comer,E.D. Fredrickson,R. J. Groebner,R.J. La Haye,L.L. Lao,E. A. Lazarus,G.A. Navratil,T.H. Osborne,B. W. Rice,S.A. Sabbagh,J. T. Scoville,E. J. Strait,T. S. Taylor +17 more
TL;DR: Using newly developed techniques and improved diagnostics, rotating wall-stabilized discharges have been maintained in the DIII-D tokamak for 30 characteristic resistive wall decay times, significantly longer than was previously achieved.
