Abstract

Deuterium re-emission measurements have been conducted on 304LN stainless steel implanted cyclicly with 10 keV D⁺ or D⁺₃ at temperatures from 35 to 95°C. Re-emission during implantation was more rapid at the higher temperatures, but slowed markedly for the higher-energy implantations. The data are consistent with a model involving diffusion in the presence of trapping sites with a recombination boundary condition. Detrapping from an ≲- 0.8 eV radiation damage trap appears to be the rate limiting step for release in the temperature range of 35 to 65°C. Molecular recombination becomes important for implantation temperatures ≳95°C. The model is applied to wall reemission calculations for tokamaks such as TFTR.
