Abstract

A new combined positron annihilation lifetime spectroscopy (PALS) and coincidence Doppler broadening (CDB) system has been constructed at Idaho National Laboratory (INL). The design and commissioning process are discussed with practical guidelines that can be followed for the installation of new systems. In addition, the new system was used to investigate defect structure in titanium and titanium deuteride samples where the deuterium concentration ranges from 0.10 to 2 x 10-5. The TiD samples were found to be largely defect free based on the positron lifetimes and S- W curves. Ratio curves of the CDB spectra showed elemental sensitivity to the deuterium in the samples, that increased with deuterium concentration.
