High-energy X-ray multimodal computed tomography at NSLS-II
What is it about?
A multimodal computed tomography experimental setup at the 28-ID-2 (XPD) beamline of the National Synchrotron Light Source II providing high-energy (>60 keV) and tunable X-ray beam size ranging from several millimetres to a few micrometres. It enables comprehensive characterization of high-Z materials - an essential capability for nuclear and advanced materials research and provides four complementary computed tomography modalities: X-ray absorption, X-ray fluorescence, X-ray diffraction, and pair distribution function. A case study using a custom-made heterogeneous sample demonstrates these abilities to simultaneously capture atomic, elemental, and morphological information.
Why is it important?
The unique combination of imaging, structural and chemical analysis enables comprehensive assessment of heterogeneous amorphous or crystalline systems, while the flexibility of this setup makes it ideally suited for in situ and operando studies of materials synthesis, transformation, and processing.
