Velocity determination of hydrogen clusters at a high density cluster-jet target — •Alexander Täschner, Alfons Khoukaz, Esperanza Köhler, Hans-Werner Ortjohann, and Tobias Rausmann — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Wilhelm-Klemm-Str. 9, D-48149 Münster

The prototype of the cluster-jet target station for PANDA has been built up at the University of Münster. This setup allows for systematic studies on the production of high density cluster-jet beams and their properties. One important parameter which determines the performance of targets for internal storage ring experiments is the target thickness. In case of the cluster-jet targets the target thickness is closely related to the mean velocity of the clusters. In this contribution we will present a technique developed for the determination of the velocity spectra of clusters. Results obtained with this method will be shown and compared to different gas dynamic models for the gas flow through the nozzle of the cluster source. Furthermore we will present first results of an extension of this technique which allows for the determination of the mass spectra of clusters.

Supported by EU (FP6 and FP7) and BMBF (06MS253I and 06MS9149I).
