Status and outlook of the CRYRING@ESR project

Once operational, CRYRING@ESR will store and decelerate ions delivered by the experimental storage ringESR at energies well below those of ESR. In addition to that, CRYRING@ESR has an electron cooler operating with an ultracold electron beam, allowing to provide cooled ion beams for precision experiments. These ions will be delivered to a broad range of experiments presently in preparation; either in-ring or extracted to a dedicated beamlinefor experiments. An overview and status report of the installation and commissioning of the CRYRING-@ESR storage ringfor highly charged ionsat the GSI Helmholtzzentrum fur Schwerionenforschung is presented. The installation of this storage ringstarted in 2014 and was completing end of 2016, when this publication was written.
