SSC magnet technology

To minimize cost of the Superconducting Super Collider (SSC) facility, small-bore high-field dipole magnets have been developed. Some of the technology developed at several US national laboratories and in industry is summarized. Superconducting wire with high magnetization current density and filaments as small as 5- mu m diameter produced with mechanical properties suitable for reliable cable production is reported. A variety of collar designs of both aluminum and stainless steel used in model magnets is described. A low-heat-leak post-type cryostat support system used and a system for accurate alignment of coil-collar-yoke in the cryostat is discussed. Brief mention is made of model magnets of 1-m, 1.8-m, 4.5-m, and 17-m lengths built during the past two years.
