Description
Haik Simon for the ELISe collaboration
At the New Experimental Storage Ring (NESR) at the FAIR facility an intersecting electron ion ring (eA collider, [1]) will allow scattering electrons with an energy of 125-500 MeV off exotic nuclei. The eA collider will enable for the first time to perform elastic, inelastic and quasielastic electron scattering off shortlived radioactive isotopes [2]. Charge distributions, transition form factors in giant resonance or electrofission experiments and spectral functions can be measured with a clean electromagnetic probe. The collider kinematics has the advantage that it will be possible to detect electrons and target like ejectile in coincidence. One of the most challenging aspects in this context is the design of a high-resolution electron spectrometer [3,4] with large acceptance adapted to the specific demands of an in-ring experiment. The impact of the worked out newest design options on the physics programme of the ELISe experiment will be discussed.
