Physics with keV Ion Beams in the Cryogenic Storage Ring CSR — •Andreas Wolf — Max-Planck-Institut für Kernphysik, 69117 Heidelberg, Germany

As a cryogenic electrostatic storage ring, the CSR offers long-time storage for ion beams with energies in the multi-keV regime. The first operation [1] showed that the 35 m diam. electrostatic lattice of the ring could be successfully realized and operated at 6 K and at a residual gas density of < 100 cm⁻³. Beam storage times reached about 10 min or more for 60 keV ion beams in the studied range of mass numbers 16–218. With this, a new tool emerges for studying internal properties and fragmentation reactions of many types of complex gas-phase ions, both anions and cations. Moreover, the ring is designed for electron cooling, presently being implemented. We discuss the experimental perspectives of this facility and of long-time stored, phase-space cooled keV ion beams more generally.
