The beamline for the UCN station begins with the double-crystal monochromator that diffracts a monochromatic neutron beam centered at 0.89 nm out of the primary polychromatic beam.
The external facility will be used for experiments that require a highly monochromatic neutron beam at 0.89 nm to create ultracold neutrons (UCN) from single phonon scattering in superfluid [.sup.4]He.
Instead we propose to conduct a separate measurement on a monochromatic neutron beam, where we can compare the neutron beam polarization determined simultaneously from Eqs.
