The DEIMOS (Dichroism Experimental Installation for Magneto-Optical Spectroscopy) beamlinewas part of the second phase of the beamline development at French Synchrotron SOLEIL (SourceOptimisée de Lumière à Energie Intermédiaire du LURE) and opened to users in March 2011. Itdelivers polarized soft x-rays to perform x-ray absorption spectroscopy, x-ray magnetic circulardichroism, and x-ray linear dichroism in the energy range 350–2500 eV. The beamline has beenoptimized for stability and reproducibility in terms of photon flux and photon energy. The main endstationconsists in a cryo-magnet with 2 split coils providing a 7 T magnetic field along the beam or2 T perpendicular to the beam with a controllable temperature on the sample from 370 K down to1.5 K.
