Synergistic effects between helium and hydrogen isotopes on gas detrapping in polycrystalline nickel
Abstract
The thermal desorption and SEM techniques have been used to study the effects of the presence of deuterium and hydrogen atoms on the retention of implanted helium in polycrystalline nickel. For samples pre-implanted with 40 keV helium to a dose of 1 × 1021ions/m2 the ratio of trapped deuterium atoms to the implanted helium was found to be about 0.4 D/He and an effective trapping energy ~ 0.5 eV was found. For samples pre-implanted with 10 keV …
