Abstract: A coil for a magnet includes a superconductor comprising a Bi2Sr2CaCu2O8+? (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.

Abstract: A device and method for sheathing shrink tubing onto materials such as wire, tape, or cables. The device cannot only sheath short lengths of shrink tubing onto material, but also sheath long lengths shrink tubing onto material. Varying embodiments of this device can insulate whole lengths of material with shrink tubing as well as covering certain sections of material for a more precise application.

Abstract: A novel method and structure for creating a high-temperature superconducting tape. The concept of the invention is to use a conductor insulation which not only electrically insulates the conductors of the coil windings from each other, but also mechanically insulates them from the much stronger encapsulant. The insulation material mechanically decouples the conductor from the encapsulant at the boundary between them, thereby preventing damage as a result of thermal and electromagnetic shearing forces. The proposed structure allows the encapsulant to continue performing its functions of preventing coarse motion and stabilizing the coil as a whole, while allowing fine relative displacements of individual coil windings caused by radial stress gradients.
