Journal ArticleDOI
Plasma-wall interaction of advanced materials
J. W. Coenen,M. Berger,Michael J. Demkowicz,Dmitry Matveev,Armin Manhard,R. Neu,Johann Riesch,B. Unterberg,Marius Wirtz,Ch. Linsmeier +9 more
TL;DR: In this article, the authors proposed to mitigate effects on material properties and introduce new release mechanisms for the first stage prototype fusion reactor considered to be the next step after ITER for the realization of fusion energy especially materials questions pose a significant challenge.
Journal ArticleDOI
Aiming at understanding thermo-mechanical loads in the first wall of DEMO: Stress–strain evolution in a Eurofer-tungsten test component featuring a functionally graded interlayer
TL;DR: In this paper, a test component with a direct Reduced Activation Ferritic Martensitic (RAFM) steel-W joint is considered, as well as a stressredistributing, functionally graded RAFM steel/W interlayer in the joint, and a parameter study with respect to geometric specifications and loads is presented.
Journal ArticleDOI

TL;DR: In this paper, the major aspects linked to the use of the JET auxiliary heating systems: NBI, ICRF and LHCD, in the new JET ITER-like wall are presented.
Journal ArticleDOI
Divertor plasma conditions and neutral dynamics in horizontal and vertical divertor configurations in JET-ILW low confinement mode plasmas
M. Groth,S. Brezinsek,P. Belo,P. Belo,M. Brix,G. Calabrò,A. V. Chankin,M. Clever,J. W. Coenen,G. Corrigan,P. Drewelow,C. Guillemaut,D. Harting,A. Huber,S. Jachmich,Aaro Järvinen,U. Kruezi,K.

TL;DR: In this paper, measurements of the low field side target plate in JET ITER-like wall ohmic and low confinement mode plasmas show minor differences in divertor plasma configurations with horizontally and vertically inclined targets.
Journal ArticleDOI
Investigation of the Impact on Tungsten of Transient Heat Loads Induced by Laser Irradiation, Electron Beams and Plasma Guns
A. Huber,Gerald Pintsuk,A. V. Burdakov,Jochen Linke,J. W. Coenen,U. Samm,B. Unterberg,V. Philipps,B. Schweer,Gennady Sergienko,A. A. Shoshin,M. Zlobinski,Marius Wirtz,Ph. Mertens +13 more
TL;DR: In this paper, the authors give an overview of different simulation methods for transient events and damages induced in tungsten. But their focus was on the resulting crack networks and specia...
