LAYOUT OF AN ACCUMULATOR AND DECELERATOR RING FOR FAIR

The main task of the RESR storage ring of the FAIR project is the accumulation of high intensity antiproton stacks. They are injected at 3 GeV after pre-cooling in the CR storage ring. The accumulation scheme is longitudinal momentum stacking with a stochastic cooling system. The requirements of the stochastic cooling system entered into the ion optical properties of the RESR lattice. The RESR can also be used for fast decelerationof rare isotope beams, which are produced with an energy of 740 MeV/u. This allows transfer of the rare isotopes at the energy required for experiments.
