Cluster birdge the gap between atomic and condensed matter. As size scalable particles in the gas phase, they are ideal model systems for analyzing of the interaction of intense laser pulses with matter. A new type of experiments, simultaneous single cluster imaging and ion spectroscopy at free-electron lasers, gives access to processes and mechanisms of this interaction on different timescales[1]. A new setup with a combination of a light scattering detector and ion spectroscopy measurement was designed which uses a table-top picosecond-UV-laser system as light source. In first measurements on large silver clusters using only ion spectroscopy, charge states up to 5+ were observed and single particle ion spectra could be achieved. The setup will be discussed and first results will be presented.
