Abstract

Retention, permeation and re-emission of deuterium implanted in Mo have been studied by measuring concentration profiles of D atoms all over the thickness of Mo membranes. The D transport behavior in the Mo membrane was different below and above 400 K. Concentration profiles of the implanted D were clearly observed from the implanted surface to the interior of the membrane below 400 K, while permeation flux of D atom was very little. At steady state, the permeation flux was less than 1% of the incident flux at RT, but it increased up to 6% at 600 K. Additionally, trapping and thermal release behaviors of D atoms at the implant surface layer of the polycrystalline membranes were examined in comparison with those in single crystals.
