Book excerpt: This paper describes the construction and operation of the small-angle neutron scattering instrument which has been set up at the Oak Ridge Research Reactor at ORNL. Motivation for work on this system to date has been the demonstration of the feasibility of the Borkowski-Kopp position-sensitive area detector and the use of pyrolytic graphite monochromating crystal pairs for small angle neutron scattering research. For a relatively modest cost, a serviceable experimental capability has been achieved. It is planned that some of the experience developed at this facility will be incorporated in a proposed large-scale apparatus at the High Flux Isotope Reactor (HFIR) and that this facility will continue in use for preliminary scattering tests.
