TL;DR: In this article, the authors review the underlying physical processes and the existing experimental database of plasma-material interactions both in tokamaks and laboratory simulation facilities for conditions of direct relevance to next-step fusion reactors.

TL;DR: In this paper, an effective particle diffusivity (Deff) that increases markedly with distance from the separatrix is characterized by a two-layer structure: Steep gradients and moderate fluctuation levels are typically found in a ∼5 mm region near the separation point, where parallel electron conduction typically dominates energy losses.

TL;DR: Bonoli et al. as mentioned in this paper measured the two-dimensional radial vs poloidal structure of edge turbulence in the Alcator C-Mod tokamak and compared with three-dimensional numerical simulations of edge plasma turbulence.

TL;DR: In this paper, the authors studied the spatio-temporal structure and dynamics of the scrape-off-layer (SOL) of a localized gas puff, and the characteristics of the spatial structure of the turbulence and their relationship to the time-averaged SOL profiles were discussed and compared with those measured on the National Spherical Torus Experiment (NSTE).

TL;DR: In this article, the edge gradients in EDA seem to be relaxed by a continuous process rather than an intermittent one as is the case for standard ELMy discharges and thus do not present the first wall with large periodic heat loads.
