Abstract :
Recently, both Alcator C-Mod and DIII-D tokamaks observed fast anomalous cross-field plasma transport in the SOL. These observations supported by theoretical studies have indicated that such transport is essentially non-diffusive and intermittent. We present the results of macroscopic plasma simulations with the UEDGE transport code including anomalous cross-field outward-directed convection for a series of low-power DIII-D shots. Our analysis of experimental and simulation data supports the view that non-diffusive transport is important for the entire edge plasma behavior in both L- and H-mode discharges.
