概要	Effects of radiation damage on the behavior of hydrogen trapped in tungsten were investigated using a mixed hydrogen-carbon ion beam and deuterium ion beam. Radiation damage was produced by 300 and 700 keV negative hydrogen ion beams. The number density of blisters formed on the radiation-damaged samples was less than an undamaged sample. SIMS measurements showed that post-implanted deuterium was mainly trapped at radiation damage sites. These results suggest that hydrogen accumulation at the grain boundaries is greatly decreased due to significant trapping of hydrogen isotopes at radiation damage sites. (C) 2008 Elsevier B.V.
