Abstract :
By combining the photon energy dispersion of a plane-grating XUV monochromator with the imaging properties of a hemispherical electron energy analyzer, energy-dispersive electron spectroscopy is possible. This multiplex technique allows the utilization of various electron spectroscopies, such as near-edge X-ray absorption (NEXAFS), photoemission (XPS) and Auger/autoionization spectroscopy, without time-consuming scanning of the photon energy. Thus, changes on short time scales may be monitored with full spectroscopic information. We present the design for an upgrade of the existing BESSY UE52-PGM beamline and the results of a pilot energy-dispersive experiment on condensed C60 molecules.
