Description
SIS300 is the second of the two planned new synchrotrons at FAIR (Facility for Antiproton and Ion Research) in Darmstadt, Germany. The high field values of up to 4.5 T for the dipoles require a so called $\cos{(\Theta)}$ design. The ramp rate of these magnets is 1 T/s, therefore special attention has been taken on the reduction of AC losses and the mechanical integrity of the magnets. For this, for example, new superconducting wires with small filament sizes of about 3 µm and a resistive CuMn matrix between the filaments has been developed. A full size model of a short curved dipole (4.5 m long) was designed, built and tested in a collaboration of GSI with groups of INFN in Genova, Milano and Salerno. Also two quadruple magnets and a steering dipole have been produced and successfully tested at IHEP, Protvino. The magnet design activities over the past years as well as an outlook into the future will be summarized.
