  Laser cooling has proven to be a viable technique for reducing the longitudinal phase space volume of bunched ion beams up to relativistic energies. Moreover, the fluorescence emitted from the ions due to deexcitation of the laser-excited cooling transition can serve as a powerful tool for atomic physics, e.g. for spectroscopy of fast transitions in highly charged ions, but also as a versatile diagnostic that can be seen as complimentary to standard, charge-based diagnostic techniques. In this presentation we will discuss how to design laser cooling setups for future high energy ion beam facilities such as FAIR and HIAF with special emphasis on the laser ion beam interaction and the resulting demands on laser systems used for reliable, turn-key laser cooling setups. We will present the state of the art of laser cooling, presenting recent results from beam times at ESR, GSI Darmstadt, and CSRe, IMP Lanzhou.

  CRYRING@ESR is the early installation of the low-energy storage ring LSR, a Swedish in kind contribution to FAIR, which was proposed as the central decelerator ring for antiprotons at the FLAIR facility. An early installation opens the opportunity to explore part of the low energy atomic physics with heavy, highly charged ions as proposed by the SPARC collaboration but also experiments of nuclear physics background much sooner than foreseen in the FAIR general schedule. Furthermore, the ring follows in large parts FAIR standards, and is used to test the FAIR control system. CRYRING@ESR has been installed behind the existing experimental storage ring ESR starting in 2013. It has a local injector that is used for commissioning. In November 2016 the commissioning of the storage ring started and a first turn was achieved. After a complete bake out cycle and substantial developments of control system, diagnosis and others, commissioning was continued in late summer 2017. Stored as well as accelerated beam has been achieved by now. The remaining step is to take the electron cooler into operation, which is planned for November this year.
