采用高能He离子预注入和氘等离子体暴露的方法研究了He对低活化铁素体/马氏体钢（RAFM）中氘（D）滞留的影响。氦损伤层的表面和内部的材料体诱导3.5 MeV的He离子轰击与和没有能量降能器，分别。铁（Fe）离子预辐照进行比较，使他的影响清楚地区分。结果表明，He离子注入RAFM后，能抑制D的滞留，而高能Fe离子的损伤对D的行为没有明显影响。当损伤层向近表面移动时，He和Fe预辐照都能提高D保持率。
Helium (He) effects on deuterium (D) retention in reduced activation ferritic/martensitic steel (RAFMs) have been studied by high-energy He ion pre-injection and following D plasma exposure. He-damaged layers at the surface and inside the material bulk are induced by 3.5 MeV He ion bombardments with and without energy degrader, respectively. Iron (Fe) ion pre-irradiation is performed as a comparison so that He effects are clearly distinguished. It has been found that He injected into the bulk of RAFMs can suppress D retention whereas D behavior is not significantly affected by the damages from high-energy Fe ion. When the damage layers are shifted to the near surface, D retention is enhanced by both of He and Fe pre-irradiation.
