Comparison of Experiment and Simulation

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.
