Abstract

In the RFX-mod reverse field pinch (RFP) experiment, electron temperature profiles often feature structures and fluctuations at fine scale. The present work aims at characterizing their occurrence and their localization, in particular by linking them to underlying tearing modes magnetic islands. The confinement characteristics are discussed, identifying analogies with respect to high scale Testructures. Finally, high frequency magnetic activity (i.e. microtearing instabilities) is confirmed to be closely correlated to the presence and proximity of temperature gradients.
