An internal cluster-jet target will be one of the two alternatively usable target stations for the planned PANDA experiment at the future antiproton accelerator HESR at FAIR. Beside several advantages such a target facility allows for high densities at the interaction point which can be adjusted continuously during operation. Since main emphasis will be put on elementary antiproton-nucleon interactions, hydrogen and deuterium are of highest interest as target material.
The prototype of this cluster target generator has been built up and set into operation successfully at the University Münster. In order to obtain information about the performance of this device as realistic as possible, a complete vacuum system in PANDA geometry has been installed, including a scattering chamber at the position of the later interaction point at PANDA as well as a beam dump system. Recent measurements proved the full compatibility with the PANDA requirements and resulted in highest hydrogen cluster target beam densities at the interaction point, i.e. 2 m behind the nozzle. The design concept of the cluster generator and the achieved performance will be presented.
