The CSR is a cryogenic electrostatic storage ring located at MPI for Nuclear Physics in Heidelberg. The CSR is designed to perform experiments on ions stored in a low thermal radiation field (~10~K) and in ultra high vacuum conditions. The experimental vacuum system of the CSR, together with all ion optical elements, is entirely housed in a cryostat. On March 17, 2014 a 50 keV Ar±beam, delivered from the new electrostatic ion accelerator platform was successfully injected and stored in the CSR at room temperature. The ion beam storage was an important mile stone in verifying the optical design and high-voltage stability. In spring 2015, the complete CSR was cooled to an average temperature below 10~K and first experiments with stored atomic and molecular ions have been successfully performed. We discuss the layout and first operation with a focus on ion beam diagnostics.
