New developments in light source magnet design

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.
