Tungsten is considered as a candidate material for first wall armor of DT fusion reactors. However, it is anticipated that tritium might accumulate in the damage defects that caused by neutron irradiation. The present study measured deuterim accumulation in tungsten specimen after high energy hydrogen ion beam irradiation for generation of irradiation damages and then low energy deuterium beams for their accumulation. As a result, the deuterium accumulation in irradiated tungsten was enhanced as high as six times than that of original specimen.
