    Abstract

    Deuterium retention in the implantation-induced defects in polycrystalline tungsten has been studied. Deuterium was implanted with different energies and concentrations of retained D were analysed with secondary ion mass spectrometry and nuclear reaction analysis. Annealings were carried out at four pre-determined temperatures corresponding to four different defect types that can trap deuterium. A quantitative number of each defect type produced by 5, 15 and 30 keV D implantation with a dose of 5.8×1016 cm−2 was obtained.
