The Superconducting Super Collider (SSC) requires superconducting correction magnets adjacent to each quadrupole magnet. The primary correction coils are for the adjustment of tune (quadrupole) and chromaticity (sextupole), and for alignment errors of the main dipoles and the quadrupole magnets. The secondary correction magnets are for the higher order correctors (quadrupoles, sextupoles and octupoles). Although at present major efforts are under way toward the design and development of SSC dipoles and quadrupoles, the correction magnets pose a different set of problems and challenges. First of all, these magnets must be packed in a small space, which requires careful compacting in the coil package. Secondly, these magnets require individual current controls, so each magnet requires individual leads. For this reason, the current must be kept low, in the range of 50 to 100 A, in order to reduce the helium boil-off. Thirdly, the use of small wires makes it difficult and challenging to wind these magnets so that they will not require training. In Phase I, this project will design and study the type of magnet best for the correction coil. This will include the comparison of coil packages, conductor and coil design, coil fabrication and assembly plans, and the design of the iron yoke and cryostat. Phase II will be to develop the conductor, fabricate model coils, and demonstrate that such coils meet the performance specifications and are cost-effective for the SSC.Anticipated Results/Potential Commercial Applications as described by the awardee: The results of this work should make possible volume production of SSC correction magnets, more than 1600 of which are required. The technology gained constitutes a substantial improvement over existing low current, training-free, superconducting magnet technology.Topic 14: Technology for the Superconducting Super Collider
