TL;DR: In this article, a simulation of N 2 seeding at both ASDEX upgrade and JET was conducted for benchmarking the critically important impurity radiation models in edge fluid codes.

TL;DR: In this paper, numerical simulations of tungsten target damage caused by the long-time plasma heat loads supporting the TEXTOR experiments are performed by the MEMOS code, which allows projections of surface damage to be made at ITER and DEMO conditions.

TL;DR: In this article, the role of potassium doping on the modification of the mechanical properties of as-annealed wires was studied, and it was found that K-doping can delay the brittleness induced by heat exposure at least up to 1600°C, while still a strong reduction of the fiber strength was observed in tests performed at elevated temperatures.

TL;DR: In this article, experiments in TEXTOR were carried out to determine effective conversion factors for different WI and WII transitions with the aid of WF6 injection into deuterium scrape-off layer plasmas in the electron temperature T e range between and.

TL;DR: In this article, an overview of experimental and modeling results along with recommendations for PFCs in ITER-like castellated structures are presented. But, there are concerns in particular on retention of codeposited radioactive fuel in the gaps.
