Spectromicroscopy techniques allow the study of local chemical states along with morphology information. At the hard X-ray nanoprobe (HXN) beamline at NSLS-II, we developed nanoscale chemical imaging with high chemical state sensitivity and micron-scale penetration depth. In addition to the chemical images, XRF and phase-contrast images collected simultaneously offer multi-modal, correlative image analysis. We also developed a highly interactive, python-based graphical user interface (NSLS-II MIDAS) that allows multi-modal analysis of nano-XANES and XRF images. Advanced supervised and unsupervised learning algorithms enable users to explore the traditional XANES analysis along with standard machine-learning tools
Scanning hard x-ray microscopy is a versatile imaging tool that offers a suite of analytic x-ray techniques for studying spatially-resolved elemental, structural and chemical variations. Recent advances in nano-focusing optics and instrumentation have pushed the frontier of the field into multi-modal imaging in 3D and with nanoscale resolution. Here we present current imaging capabilities provided by the hard x-ray nanoprobe of the National Synchrotron Light Source II at Brookhaven National Laboratory. A variety of imaging modalities (absorption, phase, fluorescence and diffraction) will be discussed, as well as the data analysis challenges associated with them. We show that x-ray imaging at about 10 nm resolution has become routine measurements at the beamline, and has been used for a wide spectrum of scientific applications.
