ID24 is an High Brilliance beamline optimized for time-resolved and extreme conditions x-ray absorption spectroscopy. With the advent of the EBS upgrade, the historic branch of the Energy Dispersive XAS beamline (EDXAS-S) has been converted into a scanning XAS beamline based on a Double Crystal Monochromator (ID24-DCM), whereas the EDXAS-L remains energy dispersive (ID24-ED) and dedicated to time resolved experiments.
