Abstract :
A brief description is given of the heavy ion synchrotron SIS, which is part of the new SIS/ESR facility at GSI. A survey of the ions that were accelerated in 1992 is presented showing the respective beam energies and intensities. Plans to increase the available beam intensities are shortly discussed. Progress in the supercycle operation for a time-shared use of up to 16 machine settings and commissioning of the beam line from the ESR back to the SIS with storage and future postacceleration of cold ESR beams are summarized. In addition, the results of recent machine experiments are presented: they include new data on Q-values for the dynamic change-over from triplet focusing at injection to doublet focusing at extraction and on machine chromaticity as well as beam profile measurements for the circulating SIS beam, which yield information on the transverse beam emittances. Finally some aspects of the present and future experimental program are discussed
