Perspectives of low-energy antiprotons physics at FAIR — •Eberhard Widmann — Stefan Meyer Institute, Austrian Academy of Sciences, Vienna, Austria

The future accelerator facility for beams of ions and antiprotons at Darmstadt will provide antiproton beams of intensities that are two orders of magnitude higher than currently available. Within the foreseen scheme, antiprotons can be decelerated to 30 MeV. The low-energy antiproton community has proposed to create a next-generation low-energy antiproton facility called FLAIR. This new facility goes far beyond the current Antiproton Decelerator at CERN by providing cooled antiproton beams using two storage rings of 300 keV and 20 keV minimum energy. The availability of low-emittance beams at these low energies will greatly enhance the density of antiprotons stopped in dilute gases or ion traps for precision spectroscopy aiming at testing CPT and QED. FLAIR will also provide slow extracted (i.e. continuous) beams of antiprotons, thereby enabling nuclear and particle physics type experiments which need coincidence techniques. Using internal targets in the storage rings, atomic collision experiments with ultra-low energy antiprotons and ions can be performed for the first time.

The availability of both antiprotons and radioctive ion beams at FAIR offers additional synergies using antiprotons as probes for the structure of unstable nuclei. An overview of the proposed experiments as well as their status will be given.
