The new electrostatic Cryogenic Storage Ring at the Max-Planck-Institut für Kernphysik in Heidelberg - operated at cryogenic temperatures below 10 K and thus at background pressures of below 10−13 mbar room temperature equivalent - is designed to perform background-free laser spectroscopy and collision experiments on cold molecular and cluster ions. Ion beam storage times of hours have been demonstrated. Thus, it is ideally suited for studies in astro-, molecular- and cluster physics. To cover this wide range of applications many different ionic systems have to be produced at nA to µA currents. A 5 m × 5 m high-voltage platform of up to 300 kV is available for the ion sources, which include a cesium sputter ion source, an electrospray ion source and a buffer-gas cooled laser-vaporization ion source in combination with a radio-frequency quadrupole ion trap for cooling and accumulation. The layout of the area as well as first ion source tests will be presented.
