Samples were implanted with 100 to 1800eV D ions in order to study implantation-driven permeation. It was found that the steady-state permeation flux was proportional to the square root of the incident D+ flux, when the latter was between 7 x 1013 and 1015/cm2s, the sample temperature was between 550 and 825K and the ion energy was between 300 and 1500eV. It was suggested that implantation-driven permeation through pure Al was controlled by the recombination of D at the target surface, and by D diffusion at the other side. The average activation energy (table 6) was equal to 59.9kJ/mol.
