Fig.5-6 Instrument used for neutron polarization analysis that uses the ³He spin filter in a small-angle neutron scattering experiment

The spin of neutrons scattered by a sample was analyzed using the ³He spin filter. A magnetic field was applied to the ³He spin filter with a Helmholtz coil to maintain ³He polarization during the experiment. By installing this instrument to beamline BL15 (i.e., TAIKAN), we verified the usefulness of the ³He spin filter to determine the structure of a material containing hydrogen atoms.
