Abstract

Self-consistent nonlinear dynamics of Energetic Particle Modes, which are relevant for burning plasma conditions, are analyzed with respect to both saturation mechanisms and energetic particle transport. It is found that a "sensitive" parameter for Tokamak equilibria with hollow-q profiles is q at the minimum-q surface, higher q corresponding to larger particle transport. This fact has clear implications on the choice of current profiles in a burning plasma. © 2002 Elsevier Science B.V. All rights reserved.
