Synopsis
FAME-UHD, the French Absorption spectroscopy beamline in Material and Environmental sciences at Ultra-High Dilution, is dedicated to high energy resolution fluorescence detected x-ray absorption spectroscopy (HERFD-XAS) for structural investigation of ultra-diluted samples. The key element of the beamline is thus a crystal analyser spectrometer, which enables XANES analyses at concentrations as low as 1ppm and EXAFS at 10ppm.
