Abstract

A reduced MHD fluid model for the unstable toroidicity-induced shear Alfvén eigenmode (TAE) is described. This consists of four coupled time evolution equations for the poloidal magnetic flux, toroidal component of vorticity, energetic particle density and parallel flow velocity, which are solved numerically using the three-dimensional initial value code FAR in toroidal geometry. The TAE mode is readily excited and exhibits similar scalings as have been predicted analytically.
