TL;DR: In this article, the authors compared the energy losses during ELMs and the corresponding time scales of the temperature and density collapse in JET-ILW baseline plasmas with and without N2 seeding with similar JETC baseline Plasmas.
Journal ArticleDOI
Preparation of TiC/W core–shell structured powders by one-step activation and chemical reduction process
TL;DR: In this paper, one-step activation and chemical reduction process as a novel wet-chemical route was performed for the preparation of TiC/W core-shell structured ultra-fine powders.
Journal ArticleDOI
Design assessment of tungsten as an upper panel plasma facing material in ITER
TL;DR: In this article, the first wall at the top of the ITER tokamaks is armoured with tungsten instead of beryllium, and the DIVIMP code is used to determine the impurity distributions.

First ERO2.0 modeling of Be erosion and non-local transport in JET ITER-like wall
Juri Romazanov,D. Borodin,A. Kirschner,S. Brezinsek,S. A. Silburn,A. Huber,V. Huber,Hugo Bufferand,M. Firdaouss,D. Brömmel,B. Steinbusch,Paul Gibbon,Ane Lasa,I. Borodkina,I. Borodkina,A. Eksaeva,A. Eksaeva,Ch. Linsmeier,Jet Contributors +18 more
TL;DR: ERO as discussed by the authors is a Monte-Carlo code for modeling plasma-wall interaction and 3D plasma impurity transport for applications in fusion research, which has undergone a significant upgrade (ERO2.0) which allo
Journal ArticleDOI
Effects of carbon impurities on the power radiation and tungsten target erosion in EAST
TL;DR: In this article, the authors used the edge fluid-plasma/kinetic-neutral code SOLPS5.0-EIRENE99, with emphasis on the C impurity transport and its effect on the power radiation and erosion of the upper W divertor target.
