Polarization-analyzed small-angle neutron scattering. I. Polarized data reduction using Pol-Corr

Pol-Corr is a free computer program that corrects for the neutron polarization inefficiencies that are characteristic of polarization-analyzed small-angle neutron scattering experiments, namely those inefficiencies associated with a static neutron polarizer, a neutron spin flipper, beam depolarization and a time-varying neutron spin analyzer. The software is designed to interface directly with small-angle neutron scattering data acquired at the NIST Center for Neutron Research, but the algorithms are generally applicable and can be readily adapted for other data formats. The explicit neutron measurements required to characterize each polarizing element are derived, and these become the input parameters for Pol-Corr.
