PUMA (French for "Photons Utilisés pour les Matériaux Anciens") is a hard X-ray imaging beamline optimized for the scientific communities of the heritage sciences. It has a 2D scanning endstation with an X-ray microbeam of 5 µm (horizontal) x 3 µm (vertical) spot size, allowing users to obtain X-ray fluorescence spectroscopy (XRF), X-ray absorption near-edge...
