  The project status of the main accelerators, the SIS100 and SIS300 synchrotrons of the FAIR project will be presented. In order to accommodate more preferable technical solutions, the structure of the magnet lattice had to be modified in both machines. After these changes, more appropriate technical solutions for the main magnets and quench protection systems could be adapted. The general machine layout and design, e.g. of the demanding extraction schemes, has been detailed and open design issues were solved. The developments and design of all major technical systems are in progress and prototyping has started or is in preparation.

  The demand for high beam intensities leads to the requirement of rapidly cycling cycling magnets for synchrotrons. An example is FAIR (Facility for Antiproton and Ion Research) at GSI, which will consist of two synchrotrons (SIS 100 and SIS 300) in one tunnel and several storage rings. The high field ramp rate (up to 1 T/s) and the repetition frequency of up to 1 Hz require R&D for the superconducting magnets of these rings. Persistent currents in the superconductor and eddy currents in wire, cable, iron and vacuum chamber reduce the field quality and generate cryogenic losses. A magnet lifetime of 20 years is desired, resulting in up to 108 magnet cycles. Therefore, special attention has to be paid to magnet material fatigue problems. R&D work is being done, in collaboration with many institutions, to reach the requirements mentioned above. Model dipoles were built and tested. The results of the R&D are reported. Full length dipoles for SIS 100 are under construction.
