The injection beam lines of the Cryogenic Storage Ring (CSR) — •Felix Berg, Klaus Blaum, Florian Fellenberger, Michael Froese, Manfred Grieser, Claude Krantz, Michael Lange, Felix Laux, Sebastian Menk, Roland Repnow, Andrey Schornikov, Robert von Hahn, and Andreas Wolf — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

At the Max-Planck-Institute for Nuclear Physics in Heidelberg an electrostatic cryogenic storage ring (CSR) is under construction. The ions for the CSR will be provided by two ion sources with up to 60kV and 300kV potential, respectively. The layout of the beamlines connecting the ion sources with the CSR will be presented. They will be merged using an electrostatic deflector with an opening in the outer electrode, thereby allowing quick switching between the two ion sources. In order to determine the influence of the opening on the beam optics the deflector has been modeled and a modified transport matrix has been derived. An additional beamline element is a detachment region for the neutralization of a negative ion beam by photodetachment. The potential of the detachment region defines the precise energy of the neutral particles. Calculations of the ion beam optics using the MAD X code will be described.
