Recent Advances in the Technology of Superconducting Accelerator Magnets

Recent progress in technology of high-current-density cables for SSC model magnets is summarized. NbTi cable with J
_c
up to 50% higher than Tevatron cable can be expected. Magnetization effects can be predicted and corrected with several new techniques. Development of Superconductor with 2-3 μm filament diameter and high J
_c
is expected.
