Effects of intermittency on turbulent transport in magnetized plasmas

Abstract:We analyze how the turbulent transport of E × B type in magnetically confined plasmas is affected by intermittent features of turbulence. The latter are captured by the non-Gaussian distribution P (φ) of the turbulent electric potential φ. Our analysis is performed at an analytical level and confirmed numerically using two statistical approaches. We have found that the diffusion is inhibited linearly by intermittency, mainly via the kurtosis of the distribution P (φ). The associated susceptibility for this lin… Show more
