The small-angle neutron scattering (SANS) machine in operation at the Oak Ridge Research Reactor (ORR) has shown the usefulness of the Borkowski-Kopp two-dimensional position-sensitive proportional counter used with double pyrolytic graphite-crystal monochromators. Although built with little latitude for machine optimization, it is capable of performing useful research in cases involving large scattering cross sections. Many of this machine's features are prototypic to the new machine under construction at the High-Flux Isotope Reactor (HFIR) for the National Center for Small-Angle Scattering Research.
