The SCS instrument offers several standard configurations for time-resolved X-ray absorption spectroscopy (XAS). The go-to method for XAS on thin samples is the beam-splitting off-axis zone plate (BOZ) XAS utilizing the DSSC detector, which provides a high-sensitivity detection scheme for measuring small transient signals. The BOZ-XAS scheme is available for experiments on solid-state thin film samples in the FFT chamber or with liquid flat jet targets in the CHEM chamber. In addition to XAS, X-ray Magnetic Circular Dichroism (XMCD) is also possible in the FFT chamber. Details of the technique can be found in Le Guyader et al., Journal of Synchrotron Radiation 30 284-300 (2023)

In addition, XAS may be measured on non-transmissive samples with point detectors (MCPs) in total fluorescence yield (TFY) mode or as a partial fluorescence yield (PFY) spectrum using the hRIXS spectrometer.
