This cold neutron instrument is used to study materials of interest in surface and interfacial science, including magnetic multilayers, polymer films, and artificial biological membranes. PBR is most commonly configured for neutron reflectometry, a technique sensitive to the depth-dependent composition, and in-plane structure of thin films and multilayer structures. PBR’s full polarization capabilities allow for polarized neutron reflectometry, which is sensitive to films' depth-dependent vector magnetization, and in-plane magnetic ordering. Depth distributions of net magnetizations as small as 20 emu/cc are routinely measured. Refrigerators, furnaces, magnets, liquid cells, and lasers are available for control of sample environment. On-site x-ray reflectometry is available for additional sample characterization. If you are interested in performing an experiment, apply for beamtime, or contact one of the instrument scientists directly. Monetary assistance may be available for new facility users.

as part of the NCNR expansion initiative the NG-1 Reflectometer has been moved to the new NG-D guide, and renamed Polarized Beam Reflectometer (PBR).  Returning users will recognize the instrument they know and love - but with improved intensity, owing to the new guide.
