Metal clusters with only a few atoms are known to exhibit new and interesting properties. In particular, the exact number of atoms has a pronounced influence on the electronic structure. The promising method to study the electronic and geometric structure of the clusters is photoelectron spectroscopy after mass-selection. So far, however, no photon source except the VUV free electron laser at HASYLAB/DESY is available, which provides the appropriate radiation of several tens of eV with sufficient intensity and thus allows to investigate the complete valence band and shallow core levels. We report on the status of a dedicated experimental setup and experiences during the first beamtime at the FEL. A BMBF funded consortium of seven groups planned the project and participates in the experiments.
