Neutron Scattering at the NIST Center for Neutron Research. Brian H. Toby, NIST Center for Neutron Research, National Institute of Standards and Technology, Gaithersburg MD 20854-8562.

The NIST Center for Neutron Research (NCNR) is currently the leading neutron facility in the US. Each year, over 1700 scientists from all areas of the country, from industry, academia, and government participate in research using NCNR facilities. These facilities include a diverse array of neutron beam instruments in the following categories: small-angle neutron scattering, thermal- and cold-neutron spectroscopy, reflectometry, crystallographic and engineering diffraction, neutron prompt-gamma, depth profiling and neutron activation chemical analysis, neutron imaging and fundamental physics measurements. Most instruments are state-of-the-art; several new instruments are under development. Researchers outside NIST can access all cold-neutron and several thermal-neutron instruments, via the Center for High Resolution Neutron Scattering, which is cofunded with the National Science Foundation, or via user programs within the NCNR. Access to the remaining instruments is possible through collaborative research projects or less formal user programs. Cost recovery is mandated for proprietary use, but access for academic and non-proprietary is research is free. Scientists without experience in neutron scattering are invited; limited travel support for new users is offered. The NCNR also gives a course in an aspect of neutron scattering each summer.
