FAME – BM30

Absorption spectroscopy, Earth Science and environment

BM30 beamline (see the public webpage or the user-dedicated webpage)

FAME is dedicated to x-ray absorption spectroscopy. Thanks to the combination of photon flux optimization, stability and fluorescence detection, the installation offers the possibility to probe chemical elements with concentrations ranging from 50ppm to 100%, in various conditions: in situ (high pressure and high temperature), operando (cell for electrochemistry or catalysis), at low temperature (for samples sensitive to beam damage or for phase transition studies).
