Abstract

A hybrid fluid kinetic model is developed for the prediction of the global linear stability of low n TAEs (toroidicity-induced Alfvén eigenmodes) in the presence of a fast ion population. This model is used to study the dependence of the TAE stability on many plasma parameters; in particular the critical volume averaged fast particle beta corresponding to marginal stability is calculated for a wide range of bulk plasma parameters and fast particle profile widths.
