X-ray Absorption Spectroscopy at ESRF
Description
One of the two instruments of FAME-PIX (French Absorption spectroscopy beamline in Material and Environmental science – Ptychography Imaging with X-ray) is dedicated to X-ray Absorption Spectroscopy. This instrument will be open to users in 2025, once the entire line has been refurbished, and will be based on the FAME line in operation from 2002 to 2023. By combining photon flux optimization and fluorescence detection, the instrument can probe chemical elements at concentrations ranging from 50ppm to 100%, under in situ conditions (high pressure & high temperature…), operando (electrochemistry or catalysis cells…), at low temperature (sensitive samples, phase transition studies…).
