A. Li Puma,J.L. Berton,Beatriz Brañas,L. Bühler,J. Doncel,Ulrich Fischer,W. Farabolini,L. Giancarli,David Maisonnier,Pavel Pereslavtsev,S. Raboin,J.-F. Salavy,P. Sardain,J. Szczepanski,D.J. Ward +14 more
TL;DR: In this paper, the authors describe the work performed for the power plant conceptual studies (PPCS) reactor model AB, a near-term fusion power reactor based on limited extrapolations from today knowledge on technology and plasma physic assumption, featuring a helium-cooled lithium lead (HCLL) blanket concept and a He cooled divertor.

TL;DR: In this paper, a new beam diagnostic based on infrared thermography has been developed for the neutral beam injectors of the stellarator TJ-II, where a highly anisotropic movable target intercepts the beam at its entrance into the massive stellarator and the thermal print of the beam is captured with a high resolution infrared camera.
