Fundamental Applications
The NI is the only device that gives direct access to the phase of neutron
waves. This ability has long been utilized to investigate fundamental problems
in quantum mechanics. Experiments such as the 4
spinor rotation of fermions, measurement of the neutron charge
radius, high precision scattering length measurements and the search for
nuclear quantum entanglement have been carried out or are in progress. These
important basic research activities are being carried out in collaboration with
physicists from U.S. and international universities and research
institutions.

Industrial Applications
Neutron interferometry is ideal for making accurate measurements of the nuclear
scattering properties of elements and isotopes. This is especially useful for
the non-destructive determination of the hydrogen content in materials. NI can
also directly measure the Fourier transform of the neutron momentum
distribution, which can used for precision studies of the surface properties of
materials. Development of neutron imaging techniques with real-world
applications is a major emphasis of the facility. In particular, neutron phase
contrast imaging, three-dimensional neutron tomography, and single crystal
diffractometers are being developed for the study of structural and bulk
properties of materials. These instruments and techniques will be valuable for
materials science research and industrial applications.
