TLDR
The ITER PFC design has now reached a rather mature stage following the 2007 ITER Design Review as discussed by the authors, and the key elements of the design, reviews the physics drivers, essentially thermal load specifications, which have defined the concept and discusses a selection of material and design issues.About:

Iterative training set refinement enables reactive molecular dynamics via machine learned forces
TL;DR: This work has implemented a refinement protocol that corrects the low extrapolation capabilities of neural networks by iteratively checking and improving the molecular dynamic simulations of reactive self-sputtering from a beryllium surface.

Plasma Heat-Flux Dispersal for ACT1 Divertor Configurations
M.E. Rensink,T.D. Rognlien +1 more
TL;DR: In this article, simulations of the heat flux on plasma-facing components from core exhaust plasma are reported for two possible ACT1 divertor configurations, one configuration uses divertor plates strongly and the other does not.

Evaluation of explosive sublimation as the mechanism of nanosecond laser ablation of tungsten under vacuum conditions
TL;DR: In this article, a non-equilibrium mechanism for nanosecond laser ablation is suggested, and its predictions are compared to the results of W experiments performed under vacuum conditions, and special considerations were taken into account for the expansion of plasma into a vacuum.

Total and partial electron impact ionization cross sections of fusion-relevant diatomic molecules
Stefan E. Huber,Andreas Mauracher,Daniel Süß,Ivan Sukuba,Jan Urban,D. Borodin,Michael Probst +6 more
TL;DR: An empirical scheme to estimate partial cross sections from the total ones based on reaction energetics and empirical threshold laws is discussed and its accuracy is explored by assessing available experimental data on total and partial EICSs.

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.
