Deuterium release from implanted beryllium and beryllium oxide [PDF]

open access: yesJournal of Nuclear Materials, 2011
Abstract The retention and release of deuterium is compared for clean metallic beryllium and beryllium oxide. Deuterium energies of 600 eV per atom are applied and implantation fluences are above the threshold for supersaturation. Desorption experiments subsequent to implantation into metallic Be are extrapolated to a perfectly homogeneous ...
