Abstract
Palladium membranes have been bombarded by beams of ∼ 10 eV atomic hydrogen with a peak flux and fluence of 4 × 1016 cm−2 s−1 and 1020 cm−2, respectively. The time-dependent permeation resulting from these exposures has been measured as a function of membrane temperature. The results have been compared with the models of Livshitz et al. and Pick et al. Permeation through conditioned membranes has agreed with these models and with earlier measurements at lower fluxes and incident energies. Effects attributed to changing surface contamination have also been observed. Aspects of a conceptual design for reducing tritium inventory in ITER through the use of superpermeability are described.
