LOREA is a beamline for the investigation of electronic structure of solids by Angle Resolved Photo-Emission Spectroscopy (ARPES) technique.
The beamline operates in the photon energy range 10-1000 eV with tunable linear and circular polarizations produced by an APPLE II helical undulator. Thanks to the energy range and the high photon flux, LOREA is suitable for high resolution VUV ARPES investigations in the 10-200 eV range, while it is feasible to extend the ARPES measurements in the 200-600 eV energy range (soft X-ray ARPES). In addition, core level photoemission, resonant photoemission and X-ray absorption spectroscopies will be accessible in the whole energy range. In a forthcoming upgrade, LOREA will be equipped with a spin-detector to perform spin-resolved ARPES (SR-ARPES) experiments.
