Abstract Scope |
Neutron imaging, similar to X-ray imaging, is a non-destructive technique that investigates the internal features/structures of an object. Neutron’s high penetration through metals and its high sensitivity to light elements (H, Li, etc.) have made neutron imaging a unique tool in many research fields such as energy storage materials, additive manufacturing, geology, nuclear materials, etc. Recently, neutron grating interferometry (nGI) has been implemented at the cold neutron imaging instrument at Oak Ridge National Laboratory (ORNL). Such technique enables simultaneous access to three imaging modalities: attenuation, differential phase contrast, and small angle scattering. Therefore, cracks, voids, and porosity ranging from hundreds of nanometers to a few micrometers can be spatially resolved in bulk materials. This work will present existing and recently developed neutron imaging capabilities at ORNL. |
