The National Institute of Standards and Technology Cold Neutron Research Facility and magnetic neutron scattering (invited)

The National Institute of Standards and Technology has under development a major Cold Neutron Research Facility which, upon completion, will make available approximately 15 new neutron‐scattering instruments located on neutron guides on the reactor cold source. This facility, which includes the National Science Foundation Center for High Resolution Neutron Scattering, will be operated as a user facility, which is open via a proposal system to all scientists. This paper briefly reviews the types of cold neutron instruments that have particular relevance to magnetic problems. A discussion is given of neutron scattering from magnetic systems with examples of problems appropriate for the enhanced energy and wave‐vector resolution of cold‐source instruments. Included is a review of new experimental results and techniques that will be available, including reflectometry and grazing‐angle diffraction, as well as more conventional techniques such as triple‐axis inelastic scattering, small‐angle scattering, and time‐of‐flight spectroscopy.
