Divertor power load investigations with deuterium and tritium in type-I ELMy H-mode plasmas in JET with the ITER-like wall
M. Faitsch,I. Balboa,P. J. Lomas,S. A. Silburn,A. Tookey,David Kos,A. Huber,E. D. L. Luna,D. L. Keeling,A. Kappatou,Jet-Efda Contributors +10 more
TL;DR: Divertor power load in tritium plasmas in type-I ELMy H-mode exhibits similar values to deuterium plasmas, confirming published scaling law predictions. The impact of type-I ELMs on the inner divertor target is slightly increased.
Experimental investigation of the microstructural changes of tungsten monoblocks exposed to pulsed high heat loads
TL;DR: In this article, the microstructure of tungsten monoblocks exposed to a few thousand cycles of combined pulsed heat loads of 10 and 20 MWm−2 (achieved via an electron beam) is thoroughly investigated.
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.
