The experimental technique of dielectronic recombination (DR) collision spectroscopy is a very successful approach for studying the properties of ions. Due to its versatility and the high experimental precision DR spectroscopy plays an important role in the physics program of the SPARC collaboration. CRYRING@ESR is particularly attractive for DR studies, since it is equipped with an electron cooler that provides an ultra-cold electron beam promising highest experimental resolving power. Here, we report on recent results from the first DR experiment with highly charged ions in the heavy-ion storage ring CRYRING@ESR of the international FAIR facility in Darmstadt.
