Description
Summary:Time-of-flight spectrometer configurations combined with position sensitive single particle counting detectors have been simulated with a Monte Carlo code to find an efficient solution for coincident low energy electron detection. Photoemission experiments on polycrystalline silver have been performed at a synchrotron radiation facility with a likewise wide-angle ARPES (angle resolved photoemission spectroscopy) setup. Low-energy electron pairs created from secondary electron emission have been detected in coincidence obtaining their full momentum vectors.
