The instrument VOLPE svolume photoemission from solidsd is an experimental setup dedicated to
high energy photoemission sPEd experiments. The instrument is equipped with an electrostatic
hemispherical spectrometer especially designed to analyze high energy electrons sup to 10 keVd
with high resolving power. In order to attain an energy resolution of a few tens of millielectron volts,
we designed and constructed a dedicated input lens system, high stability power supplies, and a low
dark-count detector and readout electronics. The system has been tested and is now operational on
the ID16 beamline at European Synchrotron Radiation Facility, where an optical layout has been
developed to perform high energy, high resolution PE experiments. First results show an overall
energy resolution selectron 1 photond of 71±7 meV at 5934 eV. The effective attenuation length of
the photoelectrons is estimated to be 5±0.5 nm at a kinetic energy of 5 keV.
