Comparison of Experiment and Simulation

  • Harald Ibach
Part of the Springer Series in Optical Sciences book series (SSOS, volume 63)


This chapter provides further details of a particular spectrometer design. Experimentally determined parameters such as current, resolution, transmission and acceptance angles at the target are compared to results from numerical simulations, and nearly perfect agreement is found. The performance of the spectrometer is demonstrated with the vibration spectrum of a monolayer of CO featuring a resolution of better than 1 meV.

    While this volume was in print a significant improvement was achieved for the current at very resolution by using a different emission system. The data for the monochromatic current track the curve with a = 2 in Fig. 8.13Google Scholar
