| Abstract Scope |
Neutron imaging is a powerful and versatile technique to probe internal structure spatially and nondestructively at the macroscale (few μm+). Advanced methods like neutron grating interferometry have allowed indirect access to smaller length scales, down to tens of nanometers, via dark-field imaging. Furthermore, sample environments like compact furnaces, load frames, and potentiostats allow for in situ and in operando measurements at application-relevant conditions. In this talk, I will discuss these advances along with some recent measurements at the Multimodal Advanced Radiography Station (MARS) at the High-Flux Isotope Reactor located at Oak Ridge National Laboratory. Some examples will include spatial mapping of hydrogen in high-temperature moderator material used in small-modular nuclear reactors, microstructure studies in aluminum alloys, and lithium diffusion during cycling in solid-state batteries.
