TL;DR: In this paper, the authors formulated the Alfven continuum damping of the toroidal eigenmodes of a large aspect ratio force-free tokamak using analytic continuation.
Abstract: The Alfven continuum damping of the toroidal Alfven eigenmodes is explicitly formulated for a large aspect ratio force‐free tokamak using analytic continuation. A set of jump conditions across the Alfven singularities are derived which have to be satisfied by the mode amplitudes. The method is then applied to a simple model equilibrium. The characteristics of the modes and their damping are investigated. The method is expected to be generalizable to models with more complete plasma dynamics.
