Abstract

Bulk ion heating rate from nonlinear Landau damping of high mode number Toroidal Alfv´ en Eigenmodes (TAEs) is calculated in the frame work of weak turbulence theory. The heating rate is lower than the nonlinear spectral transfer rate to more stable modes, but relatively insensitive to the details of linear damping mechanisms.
