Polarization characterization on the DEIMOS beamline using dichroism measurements

The DEIMOS (Dichroism Experimental Installation for Magneto-Optical Spectroscopy) beamline is a SOLEIL Phase-II beamline and has been opened to users since March 2011. It delivers polarized soft x-rays to perform x-ray absorption spectroscopy, x-ray magnetic circular dichroism and x-ray linear dichroism in the energy range 350-2500 eV. The beamline has been optimized for stability and reproducibility in terms of photon flux and photon energy. The main end-station consists in a cryo-magnet with 2 split coils allowing 7T along the beam or 2T perpendicular to the beam with a variable temperature on the sample from 370K down to 1.5K.
