SYSTEM AND METHOD TO MANAGE HIGH STRESSES IN BI-2212 WIRE WOUND COMPACT SUPERCONDUCTING MAGNETS

摘要

A coil for a magnet includes a superconductor comprising a Bi₂Sr₂CaCu₂O_8+δ (Bi-2212) high temperature superconductor (HTS) filament. The HTS filament can be encased in a protective conducting sheath. The superconductor is wound to form a coil. A reinforcement winding is wound with the superconductor. The reinforcement winding can be a wire, a tape, a band, and an outer layer encasing the superconductor filament. A method of making a coil for a magnet, a composite superconductor for a magnet, and a magnet are also disclosed.
