Neutron imaging is a non-destructive technique that investigates internal features/structures of an object. The neutron’s high penetration depth in metals and high sensitivity to light elements (H, Li, etc.) have made neutron imaging a unique tool in many research fields. Neutron grating interferometry (nGI), implemented in the Talbot-Lau interferometer setup, enables simultaneous access to three imaging modalities: attenuation, differential phase contrast, and scattering. In summary, cracks, voids, and porosity are visible in thick metal structures.
In this work, current capabilities at the neutron imaging instrument (CG-1D) at High Flux Isotope Reactor (HFIR) will be presented. Additionally, the recent progress in implementing a neutron grating interferometer will be reported.
