Plasma–Surface Interactions Under High Heat and Particle Fluxes
G. De Temmerman,K. Bystrov,F Fan Liu,Wenxin Liu,Thomas Morgan,Irem Tanyeli,van den Ad M Berg,Hui Xu,JJ Jakub Zielinski +8 more
TL;DR: In this article, a linear plasma generator is used to reproduce the expected plasma conditions and allow plasma-surface interactions studies under those very harsh conditions, where the ion energies on the divertor surfaces of a fusion device are comparable to those used in various plasma-assited deposition and etching techniques, the ion and energy fluxes are up to four orders of magnitude higher.

Yann Corre,J. P. Gunn,M. Firdaouss,S. Carpentier,M. Chantant,L. Colas,A. Ekedahl,J. L. Gardarein,M. Lipa,T. Loarer,X. Courtois,D. Guilhem,F. Saint-Laurent +12 more
TL;DR: In this paper, the Tore Supra (TS) tokamak was used to evaluate the power flowing in the scrape-off layer (SOL), and the power profile showed a narrow component near the last closed flux surface and a wide component in the rest of the SOL.

Plasma radiation dynamics with the upgraded Absolute Extreme Ultraviolet tomographical system in the Tokamak à Configuration Variable.
TL;DR: An upgraded version of a tomographical system which is built up from Absolute Extreme Ultraviolet-type (AXUV) detectors and has been installed on the Tokamak à Configuration Variable (TCV) is introduced, and the coupling between core plasma radiation and plasma-wall interaction is revealed.
