TL;DR: In this article, the authors investigated the compatibility between the plasma and low activation ferritic steel, which is a candidate material for fusion demonstration reactors, and obtained a high normalized beta plasma of βN ~ 3, having both an internal transport barrier and a steady H-mode edge.
Journal ArticleDOI
Ag L3-Edge X-ray Absorption Near-Edge Structure of 4d10(Ag+) Compounds: Origin of the Edge Peak and Its Chemical Relevance
TL;DR: The edge peak can be formally assigned to the transition from 2p to 5s enhanced by the s-d hybridization and has a negative correlation with a coordination charge but has a positive correlation with the strength of the covalent bond.
