Figure 3
(a) Schematic illustration of the X-ray diffraction and X-ray absorption spectroscopy setup, including the sample stage, PD, APD and external 2D detector. The incident X-ray and laser beams on the sample are indicated by blue and red arrows, respectively. Fluorescence and diffracted/scattered beams directed to the APD and 2D detector are shown by orange and green arrows. The dotted line represents the transmitted X-ray beam path. (b) Photograph of the sample stage, comprising three translational stages (x, y and z motions) mounted on a rotational motorized stage (θSample). Inset: schematic of the sample holder assembly designed to accommodate multiple samples. X-ray absorption spectra of a Ru metal foil across the Ru L3-edge (c) and the Ru L2-edge (d), detected by the APD using total fluence yield (TFY).
