A High Density Cluster-Jet-Target for 4π detectors — •Alexander Täschner, Alfons Khoukaz, Stephan General, Jennyfer Otte, Hans-Werner Ortjohann, and Tobias Rausmann — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Wilhelm-Klemm-Str. 9, D-48149 Münster

Cluster-jet-targets are operated successfully since many years as internal targets for storage ring experiments. In order to utilize these targets for upcoming 4π-detectors like the PANDA detector at FAIR, cluster-jet sources have to be improved with respect to the maximum target thickness to allow for highest luminosities in combination with larger distances between the cluster source and the interaction region. At the University of Münster a cluster-jet target station has been build which allows for systematic studies on the production and the properties of high-density cluster-jet beams suitable for these geometries.

In this contribution we will discuss recent results on the achieved target density. Furthermore we will present recent measurements of the velocity and the mass distribution of the produced cluster beams and studies on a prototype setup for the PANDA detector.
