The antiproton beam of the HESR at FAIR will allow to produce various hyperon-antihyperon pairs. The dedicated target system of the PANDA hyperatom setup will allow to bind negatively-charged (anti)hyperons and form heavy hyperatoms. First experiments with a 208Pb target aim at studying X-ray transitions of atomically bound Ξ−, Σ− and possibly even Σ−.
The required target system needs to be integrated in the HESR beam pipe and the PANDA target spectrometer. Consequently, it must not only be vacuum-tolerant but also radiation hard and compatible with the present strong magnetic field within PANDA. Within this environment the required redundancy of the target setup can only be achieved by multiple primary targets exchangeable by a system of piezomotors.
In this contribution we will present the final design of the two-staged target system. First tests of the reliability and the precision of the system will be presented.
