Research Institution
73026S03-I Polarized neutron scattering is an important technology for characterizing magnetic and other materials. In particular, polarized helium three (P-3He) is a novel technology for creating polarized beams and, perhaps more importantly, for the analysis of polarization in highly divergent scattered beams. To ensure accurate results, the analysis of scattered beams requires specialized targets with complex geometries. Special materials and handling procedures are required to give the targets a long useful lifetime. For example, the targets must be shielded from stray magnetic fields from nearby equipment. This project will develop and demonstrate hybrid targets made from glass and/or aluminum. Phase I will build prototype targets and measure their useful lifetimes. Targets will be filled with polarized 3He and monitored in a low-field NMR apparatus. Collaboration with neutron scattering experts will be undertaken to determine the most important target geometries for current and future experiments. Commercial Applications and Other Benefits as described by awardee: There are over nine neutron scattering centers in the U.S. and Canada and over 22 abroad. Currently, plans exist to build a new $1.4B scattering facility in the U.S. called the Spallation Neutron Source (SNS). It is expected that this technology would be used to supply targets to both existing and future facilities. The P-3He technology also could be applied to medical imaging.
