The PUMA beamline (French for "Photons Utilisés pour les Matériaux Anciens" - photons used for ancient materials) is the most recent beamline opened in SOLEIL (02/2019).
The first experimental station opened is a 2d imaging hard X-ray micro focus station, focalizing the X-rays to a 3 µm (horizontal) x 1.5 µm (vertical) spot. The analytical techniques available to the users are X-ray fluorescence spectroscopy (XRF), X-ray absorption near-edge structure (XANES) and X-ray powder diffraction (XRD). The X-ray energy is tuneable from 4 to 23 keV. Flyscan techniques insure fast data acquisition. A state of the art fluorescence microscope is available for in-situ sample observation. 
A second experimental station for 3d imaging with X-ray energies up to 60 keV will be added in the future. This station will aim to provide micron resolution with a focus on in-line phase contrast imaging.
