Preliminary investigations of storage rings for rare isotopes at the Facility for Rare Isotope Beams*

The use of storage rings is being investigated at the Facility for Rare Isotope Beams (FRIB) for two possible configurations: a low energy SR (1<20 MeV/u) and a high energy SR (>100 MeV/u). While the former has high impacts on nuclear astrophysics, the latter could be used to enable electron scattering off rare isotopes as is currently being studied at several facilities in Japan (SCRIT at RIKEN) and in Europe (ELISE at FAIR, GANIL, and DERICA in Dubna). In a first stage of this project, a model of the Test Storage Ring (TSR) at CERN was performed. Recently, we have started looking at the parameters for such a system that could be coupled with the FRIB slow and fast beamlines. Preliminary results from this work will be presented and discussed.
