Description

The absorption-desorption behavior of hydrogen isotopes in a non-evaporable getter (Zr-V-Fe) was examined, with respect to tritium storage and recovery, by mass analyzed thermal desorption spectroscopy, X-ray photoelectron and secondary ion mass spectroscopy. The activation (in vacuo at 700℃) formed pure Zr and V from the oxides of these metals initially present on the as-received surface. Fe existing as an oxide migrated into bulk during the activation.
