<i>Operando</i> anomalous X-ray powder diffraction interleaved with X-ray absorption spectroscopy using a scanning 2D imaging detector on the XMaS beamline: design, implementation and performance.

ABSTRACT: We present a method for achieving high-quality anomalous X-ray powder diffraction, interleaved with transmission X-ray absorption spectroscopy, using a flat-panel imaging detector scanned over a large angular range. Anomalous X-ray powder diffraction is a technique that enables the highlighting of specific elements within a crystal structure and pinpointing the nature of active (or inactive) sites involved in specific reactions in situ or in an operando manner. This approach enables the collection of a Q range that is not attainable using static flat-panel detectors in the absorption energy regimes used (8.94-17.5 keV). We consider the advantages and limitations of such an approach compared with alternative methods and describe in detail how it is achieved, along with
