Denoising framework for X-ray absorption spectroscopy data [PDF]

Journal of Synchrotron Radiation
X-ray absorption spectroscopy (XAS) is a powerful tool for probing the structural and electronic properties of materials, but its analysis is often challenging due to the low signal-to-noise ratio of the XAS spectra.

Turbo-XAS: dispersive XAS using sequential acquisition

Journal of Synchrotron Radiation, 1999
A new experimental technique for time-resolved X-ray absorption studies in the sub-second range has been successfully tested on the dispersive XAS beamline (ID24) at the ESRF. It consists of a sequential acquisition of energy points using the dispersive optics scheme installed on the beamline.
