The high physics potential of experiments with stored high-energy polarized antiprotons led to the proposal of PAX (Polarized Antiproton eXperiment) for the High Energy Storage Ring (HESR) of the FAIR at GSI (Darmstadt/Germany). It is proposed to polarize a stored antiproton beam by means of spin filtering with a polarized hydrogen (deuterium) gas target. The feasibility of spin filtering has been demonstrated in the FILTEX experiment. In order to optimize the spin filtering method several experimental studies with protons (at COSY/Jülich) as well as antiprotons (at AD/CERN) have to be carried out. These include the set-up of a polarized internal gas target (PIT) immersed into a low-β section, as well as a Siberian snake for longitudinal filtering. This work is supported by the BMBF, 06ER144.
