摘要
Polarized He-3 neutron spin filters can operate over a wide neutron energy range and provide a large angular acceptance. A compact He-3 neutron spin filter system has been developed for the Multi-Axis Crystal Spectrometer at the National Institute of Standards and Technology (NIST) Center for Neutron Research. Sealed He-3 cells, polarized by spin-exchange optical pumping, are used as polarizer and analyzer. The polarization of the neutrons incident on the sample is inverted by flipping the polarization of the He-3 gas in the polarizer, with only a small effect on the analyzer cells. The cell fabrication process, He-3 spin flipper, and the holding magnetic field are discussed and we present the results of a first on-line test. (C) 2010 Elsevier B.V. All rights reserved.
