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.

The rapid growth in the light source community throughout the world has served to motivate innovation in the magnet technologies that serve as the foundations for both the storage ring lattice magnet systems and the primary radiation sources, the insertion devices. Here a sampling of magnet system developments being pursued at diverse facilities are discussed, including combined-function magnets that minimize space requirements and improve accelerator performance, high performance bend magnets that provide enhanced radiation characteristics, and novel and untested concepts for future lattice magnets. Finally, we review developments in insertion devices that promise new performance characteristics to better serve the light source community.
