A State-of-the-Art Cluster-Jet Target for the PANDA Experiment at FAIR — •Philipp Brand, Daniel Bonaventura, Hanna Eick, Jost Froning, Lennart Halstenberg, Christian Mannweiler, Sophia Vestrick, Michael Weide, and Alfons Khoukaz for the PANDA collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, 48149 Münster, Germany

The PANDA cluster-jet target that will be installed at the High Energy Storage Ring (HESR) at FAIR is the world’s leading target of its kind. It allows for hydrogen target thicknesses of more than 10¹⁵ atoms/cm² at the interaction point, which is located more than 2 m below the nozzle. This is achieved by a complex machine that has been developed over the last years, including several systems for adjustment and diagnosis. Most of them are special developments just for this purpose. This also includes the diagnostic systems that will be mounted into a modified version of the cluster-jet beam dump, which is the latest development.

Furthermore, the target has already been tested extensively in our institute but also at the COoler SYnchrotron (COSY) at FZ Jülich, where the interaction of a proton beam with the target in presence of the HESR stochastic cooling devices has been studied.

The target with all the technical developments that will be installed at its final version will be presented and some results of measurements with the PANDA target will be discussed.

This project has received funding from BMBF (05P21PMFP1), GSI FuE (MSKHOU2023) and the EU’s Horizon 2020 programme (824093).
