Hard X-ray photoelectron spectroscopy on the GALAXIES beamline at the SOLEIL synchrotron

Highlights: ► We developed a new HAXPES endstation at the French synchrotron facility SOLEIL. ► The setup is operational for both solid state and gas phase experiments. ► Beamline performances allow working in the Auger Raman conditions. ► Beamline flux compensates for ionization cross section decrease at high photon energy. ► Spectrometer compensates for ionization cross section decrease at high photon energy. -- Abstract: We report on the newly operational HAXPES endstation located on the GALAXIES beamline of the SOLEIL French synchrotron facility. The photon energy provided by the beamline covers the 2.4–12 keV range, and electrons of kinetic energy up to 12 keV can be analyzed. The HAXPES station is comprised of a UHV analysis chamber designed for investigating both solid samples and gases for the first time at high kinetic energy, and a fully equipped preparation chamber. We present the first results of X-ray photoemission and photoabsorption collected with this setup
