Thermal shock tests to qualify different tungsten grades as plasma facing material
TL;DR: In this article, the authors used the electron beam device JUDITH 1 to establish a testing procedure for the qualification of tungsten as a plasma facing material and obtained results providing a general overview of the damage behaviour with quantified damage characteristics and thresholds.

TL;DR: In this article, the main wall and divertor of ITER's plasmonuclear Experimental Reactor (ITER) were investigated with metal PFCs and the results confirmed the expected benefits and limitations of all metal plasma facing components (PFCs) but also yield understanding of operational issues directly relating to ITER.

Divertor tungsten tile melting and its effect on core plasma performance
Bruce Lipschultz,J. W. Coenen,Harold Barnard,Nathan Howard,Matthew Reinke,D.G. Whyte,G.M. Wright +6 more
TL;DR: In this paper, a discussion of the implications of melting a divertor tungsten monoblock on the ITER plasma is presented, and the results show that only 15 g of Tungsten was lost from the tile over ~100 discharges.

TL;DR: In this article, the authors combine reciprocating probe measurements upstream and infrared thermography at the plasma-facing components (PFC) on plasmas in limiter configurations, and show that the common approach to predicting the power load on the limiter underestimates the heat flux at the contact point by a factor 1.5-3.

Characteristics of type I ELM energy and particle losses in existing devices and their extrapolation to ITER
A. Loarte,G. Saibene,R. Sartori,David Campbell,M. Becoulet,L. D. Horton,T. Eich,Albrecht Herrmann,G. Matthews,Nobuyuki Asakura,A. V. Chankin,Anthony Leonard,G. Porter,G. Federici,G. Janeschitz,Michiya Shimada,M. Sugihara +16 more
TL;DR: In this paper, the authors show that ELM energy losses are correlated with the density and temperature of the pedestal plasma before the ELM crash and the timescale of ELM particle fluxes.
