TL;DR: In this article, the relative Type I ELM plasma energy loss (to the pedestal energy) is found to correlate well with the collisionality of the pedestals, showing a weak dependence on the method used to achieve those pedestal plasma parameters: plasma shaping, heating, pellet injection and impurity seeding.

TL;DR: In this paper, the authors reviewed the 2014-2016 JET results in the light of their significance for optimising the ITER research plan for the active and non-active operation, stressing the importance of the magnetic configurations and the recent measurements of fine-scale structures in the edge radial electric.

TL;DR: The Wendelstein 7-X superconducting stellarator was used for the first high-performance plasma operation as discussed by the authors, achieving densities of up to 4.5 GHz with helium gas fueling.

TL;DR: In this paper, the authors review the basic physics underlying magnetic fusion: past achievements, present efforts and the prospects for future production of electrical energy, and discuss questions related to the safety, waste management and decommissioning of a future fusion power plant.

TL;DR: This special topic describes the contents of an L mode database that has been compiled with data from Alcator C-Mod, ASDEX, DIII, D III-D, FTU, JET, JFT-2M, JT-60, PBX-M, PDX, T-10, TEXTOR, TFTR and Tore Supra, and presents global and thermal scalings along with predictions for ITER.
