A polarized 3He internal target for storage rings

A polarized 3He internal target was employed at the internal target facility of the Amsterdam electron Pulse Stretcher and Storage ring (AmPS) at the Dutch National Institute for Nuclear and High-Energy Physics (NIKHEF). The unique features of internal targets such as chemical and isotopic purity, high and rapidly reversible polarization, and the ability to manipulate the target spin orientation were successfully demonstrated. A nuclear polarization of 0.50 (0.42) at a 3He gas #ow of 1.0 (2.0)]1017 at s~1 could be obtained. Operation at a nominal #ow of 1]1017 at s~1 resulted in a target thick... Mehr ...
