Dielectronic recombination (DR) collision spectroscopy is a very successful tool 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 its electron cooler provides an ultra-cold electron beam promising highest experimental resolving power. Here, we report on the first DR experiment with highly charged ions in the heavy-ion storage ring CRYRING@ESR of the international FAIR facility in Darmstadt. The recent results are well in accord with our expectations and the theory.
