Journal ArticleDOI
Final case for a stainless steel diagnostic first wall on ITER
R.A. Pitts,Boris Bazylev,Jochen Linke,I.S. Landman,Michael Lehnen,D. Loesser,Th. Loewenhoff,Mario Merola,R. Roccella,G. Saibene,M. Smith,Victor Udintsev +11 more
TL;DR: In 2010, the ITER Organization (IO) proposed to eliminate the beryllium armour on the plasma-facing surface of the diagnostic port plugs and instead to use bare stainless steel (SS), simplifying the design and providing significant cost reduction as mentioned in this paper.

TL;DR: The Magnum-PSI linear device as discussed by the authors has achieved state-of-the-art performance with a superconducting magnet, enabling steady-state magnetic fields up to 2.5 T for tens of seconds by using conventional electromagnets.
Scrape-Off Layer physics in limited plasmas in TCV
TL;DR: In this article, a method for mitigation and suppression of the near and far Scrape-Off Layer (SOL) heat fluxes through impurity seeding is proposed, and first experimental evidences are presented.
Journal ArticleDOI
Electron impact ionization cross sections of beryllium-tungsten clusters
TL;DR: In this paper, the authors reported calculated electron impact ionization cross sections (EICSs) using the Deutsch-mark (DM) and the binary-encounter-Bethe (BEB) formalisms.

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.
