Abstract
The Alfven continuum damping of the toroidal Alfven eigenmodes is expl icitly formulated for a large aspect ratio force-free tokamak using an alytic continuation. A set of jump conditions across the Alfven singul arities are derived which have to be satisfied by the mode amplitudes. The method is then applied to a simple model equilibrium. The charact eristics of the modes and their damping are investigated. The method i s expected to be generalizable to models with more complete plasma dyn amics.
