Abstract
The authors report on the first observations of driven density fluctuations at resonant layers during Alfven wave heating in a Tokamak. Whereas loading and external magnetic probe measurements show excellent agreement with the cold plasma model of the shear Alfven wave if finite omega / omega ci effects and toroidal coupling are taken into account, the new results demonstrate the importance of kinetic effects.Keywords
