| Abstract Scope |
A functional high-energy x-ray computed tomography {X/XRD/PDF/XRF}-CT 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 Nuclear Science User Facilities (NSUF) as well as NSLS-II general users. It is a novel instrument at NSLS-II which can focus the x-ray beam down to ~10 µ in the high-energy regime (>60 keV) and is intended to be a crosscutting tool that enables multi-modal characterization of high Z materials, a crucial capability for nuclear materials research. Unlike traditional x-ray computed 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 X-ray diffraction-contrast (XRD-CT) capability. With a little 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 or PDF-CT. The aim of this talk is to introduce this unique endstation and its capabilities based on various scientific examples. |
