Abstract

Polarimeters for medium-energy neutrons described here are based on the fact that scattering of polarized neutrons from unpolarized hydrogen nuclei exhibits a left-right (or an up-down) asymmetry. Configurations are described for neutron polarimeters that use the analyzing power of neutron-proton scattering from the hydrogen in an organic scintillator material. The scattering angle e and the azimuthal (out-of-plane) angle ⊘for the neutron-proton scattering event are determined from the position of the interaction in each of the two detectors involved in a given event. Described here are “V” -configuration polarimeters, an “axial” - configuration polarimeter for use with a solid-angle-limi ting aperture of a neutron spin-rotation magnet between the target and the polarimeter, and polarimeters configured with parallel planes of scintillator material.
