The experimental setup dedicated to studies of electron-ion scattering in the storage ring (ELISe) is part of the FAIR project. The FAIR facility will provide intense, high-quality secondary beams of ions and antiprotons. A new double synchrotron ring system will provide 10¹² ions/s up to uranium with an energy of 1.5 GeV/nucleon. Intense, secondary ion beams will be produced and separated with the Super-FRS. A system of storage-cooler rings will be used to reduce the emittance and energy spread of secondary beams created via fragmentation or fission reactions. An intersecting electron ion ring (eA collider) will allow to scatter 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. 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 with large acceptance adapted to the specific demands of an in-ring experiment. Charge distributions, transition form factors in giant resonance or electrofission experiments and spectral functions can be measured with a clean electromagnetic probe.

Information for staff and guests

If you are planning to come to GSI and work at the R³B experimental setup, the following information will be important for you; it is strongly recommended to use Internet Explorer/Edge and/or Mozilla Firefox, with Chrome some of the registration forms below do not function properly:

• Registration at GSI - if you register for the first time, please fill in Haik Simon as the local contact person.
• GSI Welcome Office - if you need an invitation, questions about insurance, funding oportunities...
• User service of GSI (guest house)
• Entrance requirements for caves during beam operation
• Online safety training - important: for Cave C, you need the radiation safety AND the general safety AND the Cave C safety training not older than 12 months. In case you have problems with Cave C safety training access, please contact Haik Simon. Please note, when you log in for the first time, you need to type in the local contact person. Please fill in Haik Simon. This is mandatory, otherwise Haik Simon can not asign the needed instructions to the user.
• Internet is available via wifi with an eduroam account or by a guest account (link to application form).
