Edge localized modes and the pedestal: A model based on coupled peeling–ballooning modes
P. B. Snyder,H. R. Wilson,J.R. Ferron,L. L. Lao,Anthony Leonard,T.H. Osborne,A. D. Turnbull,D. A. Mossessian,Masakatsu Murakami,Xueqiao Xu +9 more
TL;DR: In this paper, a model based on magnetohydrodynamic stability of the tokamak plasma edge region is presented, which describes characteristics of edge localized modes (ELMs) and the pedestal.
Journal ArticleDOI
A first-principles predictive model of the pedestal height and width: development, testing and ITER optimization with the EPED model
P. B. Snyder,R. J. Groebner,J. W. Hughes,T.H. Osborne,M. Beurskens,Anthony Leonard,H. R. Wilson,Xueqiao Xu +7 more
TL;DR: In this article, the authors developed and tested a model, EPED1.6, for the H-mode pedestal height and width based upon two fundamental and calculable constraints: onset of non-local peeling-ballooning modes at low to intermediate mode number, and onset of nearly local kinetic ballooning mode at high mode number.
Journal ArticleDOI
BOUT++: a framework for parallel plasma fluid simulations
TL;DR: In this paper, a modular code called BOUT++ is presented, which simulates 3D fluid equations in curvilinear coordinates, and is able to simulate a wide range of fluid models (magnetized and unmagnetised) involving an arbitrary number of scalar and vector fields.
Journal Article
BOUT++: A framework for parallel plasma fluid simulations
TL;DR: This is the first time dissipationless, initial-value simulations of ELMs have been successfully demonstrated, and the resulting mode-structures and growth-rate are found to be in good agreement.
Journal ArticleDOI
Transport by intermittency in the boundary of the DIII-D tokamak
Jose Boedo,Dmitry Rudakov,R.A. Moyer,G. R. McKee,R.J. Colchin,M.J. Schaffer,P. G. Stangeby,W. P. West,S.L. Allen,Todd Evans,R. J. Fonck,E. M. Hollmann,Sergei Krasheninnikov,Anthony Leonard,W. M. Nevins,M.A. Mahdavi,G.D. Porter,George Tynan,Dennis Whyte,Xueqiao Xu +19 more
TL;DR: Intermittent plasma objects (IPOs), featuring higher pressure than the surrounding plasma, are responsible for ∼50% of the E×BT radial transport in the scrape off layer (SOL) of the Doublet III D (DIII-D) tokamak as mentioned in this paper.
