The importance of quasi-coherent modes on transport is a growing area of research due its possible role in the development of reactor relevant scenarios. HIBP measurements have provided direct measurements of core ExB transport induced by AEs in the TJ-II stellarator <ref> A. Melnikov et al., Nucl. Fusion 50, 084023 (2010)</ref>. It was found that the AEs contribution to the frequency resolved turbulent particle transport constitutes a significant fraction of the total flux. Interestingly although most of the AEs contribute to outwards ExB flux some modes produce inward flux. | The importance of quasi-coherent modes on transport is a growing area of research due its possible role in the development of reactor relevant scenarios.
