Polarized He-3 neutron spin filter development and application at Indiana University and NIST
Type of Work
Physica B: Condensed Matter
Neutron spin filters based on polarized He-3 promise to significantly expand the range of applications of polarized neutron scattering, particularly for experiments with divergent beams. At NIST and at Indiana University, we are pursuing both methods of polarizing He-3 by optical pumping: the metastability exchange method, and spin exchange with optically pumped Rb. The status of the respective apparatus and application to small angle neutron scattering (SANS) at the National Institute of Standards and Technology (NIST) and neutron reflectometry at the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory are discussed.
