Transport processes in reversed-field-pinch plasmas: Inconsistency with the self-organized-criticality paradigm - art. no. 045001

A statistical analysis of the anomalous particle flux in the edge region of the RFX experiment has revealed that laminar times between bursts, which a ccount for more than 50% of the losses, have a power law distribution and t hat flux fluctuations are not self-similar. These properties are found in c ontrast with a wide class of self-organized-criticality models so that it i s concluded that there is no experimental evidence of avalanchelike process occurrence in the plasma of RFX.
