Abstract

The tritium inventory in plasma-facing materials (PFMs) is an important issue in fusion reactors. Tungsten (W), which is a candidate PFM, has a very low solubility for hydrogen isotopes, but intrinsic and radiation-induced defects can retain a significant amount of hydrogen. A positron annihilation technique was used to investigate the interactions between deuterium (D) and vacancies inWirradiated by Cu ions. The results indicated that vacancies were formed inWafter Cu ion irradiation, and that D atoms were trapped by these vacancies.
