Comissioning of the PANDA Cluster-Jet Target at COSY — •Benjamin Hetz, Daniel Bonaventura, Silke Grieser, Daniel Klostermann, Nils Hüsken, and Alfons Khoukaz for the PANDA collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, 48149 Münster, Germany

The internal cluster-jet target build up and already routinely in operation at the University of Münster will be the phase one target for the upcoming PANDA experiment at the antiproton storage ring HESR at FAIR. In June 2018 this target was transfered from Münster to the COSY accelerator at FZ Jülich and setup up in next to PANDA geometry. In August 2018 a first commissioning beam time has been performed with the desired PANDA at HESR target thickness of more than 1015 atoms/cm2 and first data on a rich experimental program was gained. This includes, e.g., beam-target interaction, energy loss studies, Schottky measurements, beam heating investigations, emittance growth by the target, and the physical data quality was investigated using the WASA forward detection system by studying the π0 production reaction in pp-collisions. Furthermore, the PANDA cluster-jet target has been used very successfully in additional beam times in combination with the HESR/COSY stochastic cooling and 2 MeV electron cooler, yielding important insights into the later HESR cooling performance with highest target thickness and high accelerator beam current. Results of this beam times and the upcoming experimental program of the PANDA cluster-jet target at COSY will be presented within this talk.
