Impact and mitigation of disruptions with the ITER-like wall in JET
Michael Lehnen,Michael Lehnen,G. Arnoux,S. Brezinsek,J. Flanagan,S.N. Gerasimov,N. Hartmann,T. C. Hender,A. Huber,S. Jachmich,Vasily Kiptily,U. Kruezi,G. F. Matthews,J. Morris,V. V. Plyusnin,C. Reux,V. Riccardo,B. Sieglin,P. de Vries,Jet-Efda Contributors +19 more
TL;DR: In this article, the ITER-like wall (ILW) in JET made of beryllium in the main chamber and tungsten in the divertor was studied and the main finding is a low fraction of radiation.
A Key to Improved Ion Core Confinement in the JET Tokamak: Ion Stiffness Mitigation due to Combined Plasma Rotation and Low Magnetic Shear

TL;DR: The JET experiments indicate that advanced tokamak scenarios in future devices will require sufficient rotational shear and the capability of q profile manipulation, andSimulations using quasilinear fluid and gyrofluid models show features of stiffness mitigation, while nonlinear gyrokinetic simulations do not.
Journal ArticleDOI

TL;DR: In this paper, the W-transport in the core plasma of JET is investigated experimentally by deriving the Wconcentration profiles from the modelling of the signals of the soft x-ray cameras.
Journal ArticleDOI
Analysis of metallic impurity density profiles in low collisionality Joint European Torus H-mode and L-mode plasmas
M. E. Puiatti,M. Valisa,C. Angioni,L. Garzotti,P. Mantica,M. Mattioli,L. Carraro,I. H. Coffey,Carlo Sozzi,Jet-Efda Contributors +9 more
TL;DR: Lomas et al. as mentioned in this paper analyzed the behavior of nickel in low-mode and high-mode JET discharges characterized by the application of radiofrequency (rf) power heating and featuring ITER (International Thermonuclear Experimental Reactor) relevant collisionality.
Journal ArticleDOI
Material migration patterns and overview of first surface analysis of the JET ITER-like wall
Anna Widdowson,Eduardo Alves,C. Ayres,A. Baron-Wiechec,S. Brezinsek,Norberto Catarino,J.P. Coad,Kalle Heinola,Jari Likonen,G. F. Matthews,M. Mayer,Marek Rubel,Jet-Efda Contributors +12 more
TL;DR: A detailed in situ photographic survey of the main chamber and divertor was completed in this article, where the first conclusions regarding erosion, deposition, fuel retention and material transport during divertor and limiter phases have been drawn.
