Abstract
A coil of superconducting wire for a superconducting magnet having a relaely dense and uniformly spaced winding to enhance the homogeneity and strength of the magnetic field surrounding the coil and a method of winding the same wherein the mandrel used to wind said coil comprises removable spacers and retainers forming a plurality of outwardly opening slots, each of said slots extending generally about the periphery of the mandrel and being sized to receive and outwardly align and retain successive turns of the superconducting wire within each slot as the wire is wound around and laterally across the mandrel to form a plurality of wire ribbons of a predetermined thickness laterally across the mandrel.

A method for forming a coil of superconducting wire for a superconducting magnet having an essentially dense and uniformly spaced winding to enhance homogeneity and strength of the magnetic field surrounding the coil including the steps of:
- winding said superconducting wire about a mandrel, said mandrel including removable spacing and retaining means forming a plurality of outwardly opening laterally parallel slots, each of said slots extending generally about the periphery of the mandrel and being sized to receive and outwardly align and retain successive turns of the superconducting wire within each slot as the wire is wound around and laterally across the mandrel to form a plurality of wire ribbons of a predetermined thickness laterally across the mandrel;
- effecting first bonding means to bond the turns of the superconducting wire together within each of the slots to form an integral ribbon of wire;
- disassembling the mandrel by removing the spacing and retaining means to disengage the coil from the mandrel;
- bending the coil to align the coil ribbons in a pre-established configuration;
- and
- effecting second bonding means to secure the coil ribbons in said preestablished configuration.
A mandrel for winding a coil of superconducting wire for a superconducting magnet having a relatively dense and uniformly spaced winding to enhance homogeneity and strength of the magnetic field surrounding the coil comprising removable spacing and retaining means forming a plurality of outwardly opening laterally parallel slots, each of said slots extending generally about the periphery of the mandrel and being sized to receive and outwardly align and retain successive turns of the superconducting wire within each slot as the wire is wound around and laterally across the mandrel to form a plurality of wire ribbons of a predetermined thickness laterally across the mandrel.
A coil of superconducting wire for a superconducting magnet having a relatively dense and uniformly spaced winding to enhance the homogeneity and strength of the magnetic field surrounding the coil comprising windings formed into a plurality of wire ribbons across the width of the coil, each of said wire ribbons including a predetermined number of wire turns and being aligned and bonded in an essentially side-by-side parallel fashion to the other ribbons across the width of the coil to form a coil of a predetermined cross-sectional profile.
