| Abstract Scope |
A functional high-energy x-ray computed tomography instrument has been commissioned at the 28ID-2-D endstation of NSLS-II to provide synchrotron-based characterization resources for the nuclear science community under the umbrella of NSUF. It is a novel instrument which can focus the x-ray down to ~10µ in the high-energy regime and intended to be a crosscutting tool enabling multi-modal characterization of high-Z materials. Unlike traditional x-ray tomography that is solely based on X-ray absorption contrast (X-CT), this instrument can provide useful material properties such as phase identification, lattice parameters, phase fraction, grain size, micro strain via diffraction-contrast (XRD-CT). With a quick change in the setup, pair distribution function contrast (PDF-CT) mode - which can be very useful especially for non-crystalline materials - can be enabled. Elemental contrast (XRF-CT) is collected simultaneously alongside XRD-CT/PDF-CT. The aim of this talk is to introduce this unique endstation and its capabilities based on various scientific examples. |
