Design of the New Experimental Storage Ring for operation with ions and antiprotons

The New Experimental Storage Ring (NESR) of the Facility for Antiproton and Ion Research is designed for versatile operation with ions and antiprotons. Both stable ions and rare isotope beams will be used for internal experiments. The ion beams can be decelerated to a minimum energy of 4 MeV/u and extracted to a low energy experimental area. Antiprotons will be decelerated from 3 GeV to a minimum energy of 30 MeV and transferred to the Facility for Low-energy Antiproton and Ion Research. Electron cooling will provide high quality beams for experiments, assist the deceleration process, and allow the accumulation of rare isotope beams by stacking in longitudinal phase space. Specific rf systems are foreseen for the various operation modes.
