Design Study of Superconducting Magnets for the Super-KEKB Interaction Region

The Super-KEKB is the next generation collider for B factories, and its target luminosity is 4 × 10³⁵cm^-2s^-1. From the various points of view, the reality of this machine was discussed, and the magnet system in the interaction region has been also studied intensively. Especially, the study of the superconducting magnet system, which consists of the final focus quadrupoles and the compensation solenoids, has progressed. In this paper, the layout and the parameters of these superconducting magnets are reported.
