Performance of a hydrogen/deuterium polarized gas target in a storage ring

The performance of a hydrogen/deuterium polarized gas target in a storage ring is presented. The target setup consisted of an atomic beam source, a cryogenic storage cell and a Breit-Rabi polarimeter. High frequency transition units were constructed to produce vector polarized hydrogen and deuterium, or tensor polarized deuterium. The nuclear-polarized gas was produced in an atomic beam source (ABS) and injected into the feed tube of a storage cell. The electron beam encountered no window materials when passing through the target which resulted uncertainities in scattering from contaminants were small
