Superconducting magnet needs for the ILC

The ILC reference design report was completed early in February 2007. The magnet systems group was formed to translate magnetic field requirements into magnet designs and cost estimates for the reference design. As presently configured, the ILC will have more than 13,000 magnetic elements of which more than 2300 will be based on superconducting technology. This paper will describe the major superconducting magnet needs for the ILC as presently determined by the area systems groups, responsible for beam line design, working with the magnet systems group. The superconducting magnet components include main Linac quadrupoles, positron source undulators, damping ring wigglers, a complex array of final focus superconducting elements in the beam delivery system, and large superconducting solenoids in the e⁺ and e^- sources, and the ring to main Linac lines.
