Holties}, title = {Comparison between measurements of the poloidal distribution of magnetic fluctuations and predictions of theoretical models during TAE activity}, abstract = {Fluctuations produced by beam-driven toroidicity-induced Alfven eigenmode (TAE) activity in the DIII-D tokamak are measured by a poloidal array of magnetic probes and compared with the wavefields computed by two theoretical models. Fluid resistive models compute continuum damped TAEs. A kinetic plasma model that retains Landau damping and finite Larmor radius effects computes global drift-kinetic Alfven eigenmodes. The phases of the probes disagree with both theoretical predictions, while the amplitudes agree best with the kinetic model.}, year = {1997}, journal = {Nuclear Fusion}, volume = {37}, number = {10}, pages = {1411-1417}, month = {Oct}, isbn = {0029-5515}, doi = {10.1088/0029-5515/37/10/i07}, language = {eng}, }
