Description
Polarized neutron scattering is a powerful tool to study from materials to fundamental physics,and polarized $^3$He gas is now playing an important role at high flux neutron sources as neutron spin filters (NSF). At the spallation neutron source in J-PARC (Japan Proton Accelerator Research Complex), a polarized inelastic neutron spectrometer, POLANO, is now under commissioning, and an in-situ polarized $^3$He NSF is about to be installed in the instrument for the incident neutron beam polarization. The in-situ polarized $^3$He NSF has been originally designed and build for POLANO but it can be used in other instruments with minimal modification because of its compact size and versatility.
We will present some techniques developed for the in-situ polarized $^3$He NSF as well as other measurements carried out with $^3$He NSF at J-PARC.
