The high‐order structure functions have been analyzed to characterize the edge plasma intermittency in fusion devices. The scaling properties of edge turbulence have shown a strong deviation from a prediction of the Kolmogorov's K41 model. The turbulent fluctuations demonstrate a multifractal statistics. The generalized scale invariance has been observed by involving the Extended Self‐Similarity hypothesis. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
