Journal ArticleDOI
Production of tungsten-fibre reinforced tungsten composites by a novel continuous chemical vapour deposition process
TL;DR: In this paper, a new set-up utilizing a continuous deposition process was developed and used for the fabrication of first samples, which were examined by microstructural analysis and compared to material produced by the standard technique.
Journal ArticleDOI
An improved model for the accurate calculation of parallel heat fluxes at the JET bulk tungsten outer divertor
D. Iglesias,P. Bunting,J. W. Coenen,G. F. Matthews,R.A. Pitts,S. A. Silburn,I. Balboa,I. Coffey,Yann Corre,R. Dejarnac,Jonathan Gaspar,Estelle Gauthier,S. Jachmich,K. Krieger,S. Pamela,V. Riccardo,M.F. Stamp,Jet Contributors +17 more
TL;DR: Parallel heat flux calculations at the JET divertor have been based on the assumption that all incoming heat is due to the projection of the heat flux parallel to the magnetic line, q, plus a const...
