Abstract
Neutron spin filters based on polarized He-3 are useful over a wide neutron energy range and have a large angular acceptance among other advantages. T wo optical pumping methods, spin-exchange and metastability-exchange, can p roduce the volume of highly polarized He-3 gas required for such neutron sp in filters. We report a test of polarizers based on each of these two metho ds on a new cold, monochromatic neutron beam line at the NIST Center for Ne utron Research. (C) 2000 Elsevier Science B.V.
