SIS - A Two Stage Synchrotron Facility for Heavy Ions

The GSI studies for a new large 14 GeV/u heavy ion facility have been continued. Once again concepts for two-stage facilities have been studied that combine a fast cycling booster synchrotron with a slowly cycling high energy synchrotron. In the proposed facility the total power consumption will be moderate, when superconducting magnets are used in the high energy synchrotron, and the operational versatility will allow experiments with free choice of ion species and energy in both energy ranges, 20 to 1000 MeV/u as well as 1 to 14 GeV/u. With respect to the two-stage concept the design of a new high current linear accelerator has been optimized.
