TL;DR: In this article, the retention of deuterium in polycrystalline W foils has been measured as a function of ion fluence and implantation temperature, and the retention enhancement is attributed to an increase in the D diffusion coefficient, which allows a greater diffusion depth.

TL;DR: In this paper, the authors performed laboratory-scale studies to investigate mechanisms that influence hydrogen transport and retention in beryllium foil specimens of rolled powder metallurgy product and rolled ingot cast beryellium.

TL;DR: In this paper, deuterium thermal absorption and desorption experiments were conducted in high-purity Be, BeO and Be2C samples, and the authors used ion-beam analysis to measure the surface contamination and near-surface deutrium concentration (up to depths of 500 nm).

TL;DR: In this paper, the deuterium distributions were determined using 3 He-D nuclear reaction analysis, at 300-800 K. The results indicated that considerable diffusion occurred both during the implantations and during the subsequent analysis.

TL;DR: In this paper, thermal desorption spectroscopy of beryllium tiles exposed to a D-D plasma in JET has been studied, and the amount of deuterium detected varied from a low of 8 × 10 21/m 2 to a high of 2.1 × 10 23 /m 2.
