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.

COSY, a COoler SYnchrotron and storage ring has been initially equipped with a low energy electron cooler. It was mainly used to improve the quality of the beams extracted to fixed-target experiments, to enable transverse stacking of polarized beams to be used with targets in the ring, and to improve the beam lifetime for internal experiments. In 2013 a high-energy e cooler covering the entire energy range of COSY was added. Since then high-energy e cooling has been demonstrated and dedicated cooling beam studies with dc and bunched proton beam have been carried out. Furthermore, the cooling process in presence of an internal cluster jet target continuously affecting the circulating beam was studied. We review the status of electron-cooling activities at COSY, present the latest experimental results, discuss problems encountered and possible cures, and provide insights into the activities envisaged for the next year.
