Abstract

Reemission retention and permeation behaviors of deuterium in Al, Ni, Cu and 304SS membranes have been studied for 5 keV D2+ implantation at temperatures between RT and 493 K. The D atoms trapped in the membranes as well as the permeated D atoms were simultaneously detected by means of an elastic recoil detection (ERD) analysis technique of transmission geometry. The amounts of the trapped and permeated D atoms were measured as a function of fluence at various temperatures. From these experiments, we estimated the fractions of trapping, permeating and reemitting D fluxes at the steady state, where the reemission fraction was evaluated by subtraction of the trapping and permeating fluxes from the incident flux. The observed transport behaviors were analyzed to determine the recombination coefficients in these metals.
