TL;DR: In this paper, a multi-machine database for the Hmode scrape-off layer power fall-off length, λq in JET, DIII-D, ASDEX upgrade, C-Mod, NSTX and MAST has been assembled under the auspices of the International Tokamak Physics Activity Regression inside the database.

TL;DR: In this article, a survey of the causes of all 2309 JET disruptions over the last decade of JET operations was carried out to obtain a complete picture of all possible disruption causes, in order to devise better strategies to prevent or mitigate their impact.

TL;DR: In this article, the ITER-like wall (ILW) experiment at JET was used to demonstrate the plasma compatibility with metallic walls and the reduction in fuel retention, which confirmed the expected predictions concerning the plasma-facing material change in ITER and is in line with identification of fuel co-deposition with Be as the main mechanism for the residual long-term retention.

TL;DR: In this article, a fast disruption mitigation valve has been installed at JET to study mitigation by massive gas injection and different gas species and amounts have been investigated with respect to timescales and mitigation efficiency.

TL;DR: In this paper, a Thomson scattering system is developed for Joint European Torus with 15"mm spatial resolution and a foreseen accuracy for temperature better than 15% at a density of 1019"m−3.
