The article discusses the use of Neutron Spin Filters (NSFs) on the BT-7 triple axis spectrometer at NIST. The NSFs serve as both polarizers and analyzers, with ³He cells placed inside mumetal shielded boxes or solenoids. In-situ NMR monitoring is used to precisely control and measure the neutron spin polarization. This configuration enables researchers to study magnetic properties of materials with high accuracy and precision. The article provides information for researchers and scientists working in neutron scattering.
