Polarized beam operation of the hybrid spectrometer at the pulsed spallation neutron source

Abstract The concept of a neutron hybrid spectrometer (HYSPEC) combines the time-of-flight spectroscopy with the focusing Bragg optics and incorporates a polarized beam option. Here, we describe the polarization analysis scheme proposed for HYSPEC and quantify its performance via the Monte-Carlo simulations. We find that the broadband supermirror-bender transmission polarizers provide reasonably good polarization analysis capability within a ∼8–10 meV energy window for scattered neutron energies in the thermal range, up to ∼25 meV.
