TL;DR: In this paper, the results of the hybrid simulations of the toroidicity-induced Alfven eigenmodes, reversed shear Alfven and energetic-particle continuum modes were compared with the results from an ideal MHD eigenvalue code, which showed agreement with respect to the mode frequency, dominant poloidal mode numbers, and radial location.

TL;DR: In this paper, Toroidal Alfven Eigenmodes (TAEs) with toroidal mode number (N) up to |N|=12 were actively driven with a set of in-vessel antennas, and were then used to infer the value of the plasma isotopic composition at different radial positions.
