Coincidence Imaging and Pulsed Molecular Beams

The detection and in particular imaging of charged particles is the underlying principle of the photoelectron-photoion coincidence imaging machine that is used in all the experiments described in this thesis. Before the photoelectron-photoion coincidence apparatus is described in section 2.2.1, a short review of the developments in charged particle imaging is given. Subsequently, the calibration of the electron and the ion detector is discussed. Finally, the molecular beam and in particular the implementation of a cantilever piezo valve is described in detail in section 2.4.
