At the future FAIR project in Darmstadt/Germany low energy antiprotons will be available at FLAIR, the Facility for Low energy Antiproton and Ion Research. Within the FLAIR LoI it is proposed to study the production of strangeness S = -2 baryonic states based on ideas proposed for LEAR.With stopped antiprotons a very efficient reaction chain for the production of slow {xi} hyperons can be initiated. The special feature of this reaction channel is the low momentum of the produced {xi} hyperon down to zero MeV/c recoil momentum. These slow {xi} particles can go into interacting {xi}N systems which can couple to YY or might also directly connect to the H particle, if it exists.From the experimental point of view the delayed decays of the strange exit particles allows a highly selective trigger on these reaction channels and the event reconstruction is relatively simple. A non magnetic detection system with track reconstruction ability is sufficient for the complete kinematical reconstruction.
