A New High-Intensity Synchrotron SIS100 with Strong Bunch Compression for GSI

GSI has proposed a new synchrotron and storage ring facility for the future development of research in Nuclear Physics and in Plasma Physics. A new synchrotron accelerator (BR=100 Tm) with strong bunch compression capability will be the main machine in the new accelerator complex. One of its major design goals is to deliver intense uranium (q=28+) beams at 0.4-2.7 GeV/u for the production and subsequent storage of exotic nuclei and antiprotons as well as for plasma physics experiments. The 100 Tm machine which is combined with a second synchrotron stage in the same machine tunnel (BR = 200 Tm) is equipped with a rf-compression system for the generation of short, high power heavy ion pulses. By means of this compression system single bunches of up to 20 ns can be generated in the fast extraction mode.
