Status of the low-energy electron cooler for the Cryogenic Storage Ring in Heidelberg — •Stephen Vogel¹, Claude Krantz¹, Andrey Shornikov², Klaus Blaum¹, and Andreas Wolf¹ — ¹Max Planck Institute for Nuclear Physics, Heidelberg, Germany — ²CERN, Genève, Switzerland

The Cryogenic Storage Ring (CSR) is under construction at the Max Planck Institute for Nuclear Physics in Heidelberg. It will feature a low-energy electron cooler, which will allow cooling of beams with a charge-to-mass ratio q/m of 1 to 1/160 e/amu. This corresponds to a cooling energy range of 1 to 163 eV. The two different operation modes of CSR, cryogenic at 10 K and room temperature, impose high requirements on the design of the cooler. The electron source is a GaAs photocathode which has been used at the Test Storage Ring (TSR). The electron cooler will improve the storage time and emittance of beams significantly. In addition electron-ion collisions with electron energies up to 1 keV (lab frame) will be possible to perform electron-ion collison experiments with a wide range of atomic and molecular species. The design and status of the CSR electron cooler will be presented.
