Phys. Rev. Lett. 87, 045001 (2001) [4 pages]Transport Processes in Reversed-Field-Pinch Plasmas: Inconsistency with the Self-Organized-Criticality ParadigmReceived 30 March 2001; published 5 July 2001 A statistical analysis of the anomalous particle flux in the edge region of the RFX experiment has revealed that laminar times between bursts, which account for more than 50% of the losses, have a power law distribution and that flux fluctuations are not self-similar. These properties are found in contrast with a wide class of self-organized-criticality models so that it is concluded that there is no experimental evidence of avalanchelike process occurrence in the plasma of RFX. © 2001 The American Physical Society URL:
