Capability Summary
Oak Ridge National Laboratory’s work in neutron and X-ray scattering integrates measurement, analysis, and application, conducting basic and applied studies using techniques such as Mössbauer spectroscopy, X-ray computed tomography, and other complementary characterization techniques. Studies are conducted on crystalline and amorphous materials ranging from phase identification to residual stress to high temperature X-ray diffraction to inelastic scattering. Researchers take advantage of ORNL facilities including the Spallation Neutron Source and High Flux Isotope Reactor, as well as resources at other labs and facilities.
