Abstract

We present recent results obtained with a novel spectrometer developed within the EU projectVOLPE (VOLume PhotoEmission from solids with synchrotron radiation), now operational at ESRF (Beamline ID16), where we were able to achieve high energy resolution as well as good statistics photoemission spectra up to 6–8 keV of photoelectron kinetic energy. The spectrometer is a hemispherical deflector analyzer with electrostatic input lens and 2D position sensitive detector. Ag 3d, Au 4f and valence band spectra have been measured from polycrystalline Ag and Au, displaying an overall energy resolution (photons + analyzer) of about 71 meV at 6 keV, as measured at 18K on the Fermi edge. The corresponding resolving power of 8×104 is one of the highest values achieved in photoemission measurements from solid samples.
