Theory of Edge Localized Mode Suppression by Static Resonant Magnetic Perturbations in the DIII-D Tokamak
Richard Fitzpatrick
The plasma response to an externally generated, static, n=2, resonant magnetic perturbation (RMP) in the pedestal region of DIII-D discharge #158115 is investigated. In this partic…
Vacuum Solution for Solov'ev's Equilibrium Configuration in Tokamaks
Tao Xu, Richard Fitzpatrick, Francois L. Waelbroeck
In this work, we have revisited the Solov'ev analytical solution for a tokamak equilibrium. We point out that the vacuum solution in the Solov'ev formulation is inapplicable, since…
Two-Fluid Nonlinear Theory of Response of Tokamak Plasma to Resonant Magnetic Perturbation
Richard Fitzpatrick
A comprehensive two-fluid nonlinear theory of magnetic reconnection driven at a single, tearing-stable, rational surface embedded in an H-mode tokamak plasma is presented. The surf…
Effect of Nonlinear Energy Transport on Neoclassical Tearing Mode Stability in Tokamak Plasmas
Richard Fitzpatrick
An investigation is made into the effect of the reduction in anomalous perpendicular electron heat transport inside the separatrix of a magnetic island chain associated with a neoc…
An Improved Neoclassical Drift-Magnetohydrodynamical Fluid Model of Helical Magnetic Island Equilibria in Tokamak Plasmas
Richard Fitzpatrick
The effect of the perturbed ion polarization current on the stability of neoclassical tearing modes is calculated using an improved, neoclassical, four-field, drift-MHD model. The…
Two-fluid magnetic island dynamics in slab geometry: II - Islands interacting with resistive walls or static external resonant magnetic perturbations
Richard Fitzpatrick, Francois L Waelbroeck
The dynamics of a propagating magnetic island interacting with a resistive wall or a static external magnetic perturbation is investigated using two-fluid, drift-MHD theory in slab…
