Simultaneous ion and gas driven permeation of deuterium through nickel

The permeation rate of deuterium through nickel exposed to a deuterium ion beam has been measured as a function of temperature (100–1000°C), incident ion flux ( 0.2−1.1 × 10 15 D-atom cm −2 s −1 ), incident ion energy (1–2.5 keV/D-atom), and deuterium partial pressure. The results are analyzed with...

Summary:The permeation rate of deuterium through nickel exposed to a deuterium ion beam has been measured as a function of temperature (100–1000°C), incident ion flux ( 0.2−1.1 × 10 15 D-atom cm −2 s −1 ), incident ion energy (1–2.5 keV/D-atom), and deuterium partial pressure. The results are analyzed with a model which is developed to describe ion driven permeation when gas driven permeation coexists; the rate-limiting process of recycling during ion implantation is identified as surface recombination above 400°C and as bulk diffusion below 300°C, and the recombination coefficient is estimated. The model predicts the whole parameter dependence observed. The permeation spike is also investigated.
