An interesting result of the self-organization processes in RFX-mod high current discharges is the development of strong electron transport barriers. An internal heat and particle transport barrier is formed when a bifurcation process changes the magnetic configuration into a helical equilibrium (SH) and chaos reduction follows, together with the formation of a null in the q shear. Turbulence analysis shows that the large electron temperature gradients are likely limited by the onset of micro-tearing modes. A new type of electron transport barrier with strong temperature gradients develops more externally (r/a = 0.8), independently on the presence of the helical equilibrium, accompanied by a 30% improvement of the global confinement time. Both types of barriers occur in high current low collisionality regimes. Analogies with Tokamak and Stellarators are discussed. (literal)
