Abstract / Description:A small cryogenic storage ring is presently being developed at MPI-K, Heidelberg. The energy in the machine will be variable from 20 keV to 300 keV. Electron cooling will be applied to produce a high quality ion beam. The ring shall accommodate slow, vibrationally and rotationally cooled molecular ions and highly charged ions from the EBIT ion source. Moreover, it will serve as a test facility for the low-energy antiproton ring planned within the FLAIR collaboration to be installed at the future GSI facility. A number of technological challenges have to be handled: Especially highly charged ions at low energies require a vacuum in the order below 10-14 mbar to achieve reasonable lifetimes. Therefore - and for enabling experiments with rotationally cold molecules - the complete machine will be cooled down to below 5 K. Moreover, experiments with reaction microscopes to determine the full kinematics of ion-atom or molecule collisions require a bunched operation with a bunch length less than 2 ns. The preliminary design of the machine, its optical elements and the lattice functions are given and first ideas about the vacuum chamber design are described in this paper.
