Design and Commissioning of a new Ion Momentum Imaging Spectrometer

POSTER

Abstract

We have built a velocity map ion imaging spectrometer designed for valence and core-shell photoionization studies of molecules, ions and clusters. The spectrometer is equipped with 4 electrostatic lenses, which focus the fragment ions on a position-sensitive Roentdek Hex-80 anode. It can be employed for electron-ion coincidence experiments in both multi- as well as two-bunch mode using static or pulsed ion extraction fields. First results for the photoionization of small molecules and clusters will be presented.
