CSR- A CRYOGENIC STORAGE RING AT MPI-K

LATTICE DESIGN 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 [1]. Moreover, it will serve as a test facility for the low-energy antiproton ring planned within the FLAIR collaboration [2, 3] 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 10-13 mbar to achieve reasonable lifetimes. Therefore- and for enabling experiments wit
