A simple and cost effective inverse photoemission spectrograph based on a spherical grating with very large optical acceptance ( f/2.8) is described. The system works in the 10–25 eV photon energy range. The dispersed photons are detected by a detector assembly based on a microchannelplate and consisting of twelve independent channels. Measurements are taken in the isochromat mode by sweeping the impinging electron energy, and the acquisition of the twelve channels is done in parallel. As an example of the apparatus performances data on polycrystalline Pt are presented.
