Reflectometry uses neutrons scattered at grazing angles as a probe of depth-dependent composition and in-plane correlations in flat samples. By using a polarized beam, neutron reflectivity is sensitive to the magnetic, as well as the chemical, composition of samples. Examples of materials studied include magnetic nanostructures, biological membranes, and thin polymer films. The NCNR has three reflectometers, each specially configured for different types of research:

  • NG-1 Polarized Beam Reflectometer (polarized beam capability)
  • ANDR/MAGIK (equipped with a 2-D position sensitive detector)
  • NG-7 Horizontal Geometry Reflectometer ( used for liquid samples )
