Journal ArticleDOI
Edge radial electric field structure and its connections to H-mode confinement in Alcator C-Mod plasmas
R. M. McDermott,Bruce Lipschultz,Jerry Hughes,Peter J. Catto,A.E. Hubbard,Ian H. Hutchinson,Robert Granetz,Martin Greenwald,Brian LaBombard,Kenneth D. Marr,Matthew Reinke,J. E. Rice,D.G. Whyte,D. Alcator C-Mod Team +13 more
TL;DR: Marmar et al. as discussed by the authors used high-resolution charge exchange recombination spectroscopic measurements of B5+ ions for the first spatially resolved calculations of the radial electric field (Er) in the Alcator C-Mod pedestal region.
Journal ArticleDOI
Role of trapped electron mode turbulence in internal transport barrier control in the Alcator C-Mod Tokamak
D.R. Ernst,P.T. Bonoli,Peter J. Catto,William Dorland,C.L. Fiore,Robert Granetz,Martin Greenwald,Amanda Hubbard,Miklos Porkolab,M. H. Redi,John Rice,K. Zhurovich +11 more
TL;DR: In this paper, nonlinear gyrokinetic simulations of trapped electron mode (TEM) turbulence, within an internal particle transport barrier, are performed and compared with experimental data.
Journal ArticleDOI
Drift-ordered fluid equations for field-aligned modes in low-β collisional plasma with equilibrium pressure pedestals
Andrei N. Simakov,Peter J. Catto +1 more
TL;DR: In this paper, a system of nonlinear equations for plasma density, electron and ion temperatures, parallel ion flow velocity, parallel current, electrostatic potential, perturbed parallel electromagnetic potential, and a perturbed magnetic field is derived.
Journal ArticleDOI
Dipole equilibrium and stability
Jay Kesner,Andrei N. Simakov,D. T. Garnier,Peter J. Catto,R. J. Hastie,Sergei Krasheninnikov,Michael E. Mauel,T. Sunn Pedersen,Jesus J. Ramos +8 more
TL;DR: In this article, a dipole field model was used to investigate the stability properties of a plasma confined in dipole fields and found that equilibria exist at all beta values and these equilibrium conditions are stable to ballooning modes when they are interchange stable.
Journal ArticleDOI
Kinetic effects in tokamak scrape-off layer plasmas
Oleg Batishchev,Sergei Krasheninnikov,Peter J. Catto,A. A. Batishcheva,D. J. Sigmar,Xueqiao Xu,J. A. Byers,T.D. Rognlien,Ronald H. Cohen,M. M. Shoucri,I. P. Shkarofskii +10 more
TL;DR: In this paper, the authors developed one spatial dimension and two velocity variables, fully kinetic, collisional, and time-dependent particle-in-cell code for scrape-off layer plasmas.
