Abstract

In an effort to better understand the structural changes occurring during hydrogen loading of erbium target materials, we have performed in situ D₂ loading of erbium metal (powder) at temperature (450 °C) with simultaneous neutron diffraction analysis. This experiment tracked the conversion of Er metal to the α erbium deuteride (solid-solution) phase and then into the β (fluorite) phase. Complete conversion to Er D_2.0 was accomplished at 10 Torr D₂ pressure with deuterium fully occupying the tetrahedral sites in the fluorite lattice.
