At the CSR, a cryogenic electrostatic storage ring, first experiments studying low-energy ion reactions with atoms, photons or electrons are upcoming in near future. At beam energies of 20 keV to 300 keV per charge unit and 35 m circumference the CSR is designed to allow experiments in a cryogenic environment providing conditions of extremely low vacuum (1 x 10E-13 mbar) and temperature (10K). Moreover, phase space cooling by electrons is under construction to be installed as the next step.

In spring 2014 a 50 keV Ar+-beam could be successfully stored in the CSR still operating at room temperature. Additionally beam diagnostics as well as particle detectors for neutral and charged fragments have been successfully tested.

Presently preparations are finalized for the first complete cryogenic cool down of the CSR, in order to start first exploratory experiments with stored atomic and molecular anions and cations in spring 2015.
