Abstract
Superconducting cables, wires and methods of making the same are disclosed. The cables can offer improved flexibility while maintaining a high current carrying capacity. Advantageously, the superconducting filaments of the cables can be formed from relatively brittle materials having comparatively high critical temperatures and/or comparatively high critical magnetic fields. Magnet systems can be formed using these cables without using the conventional “react-then-wind” method.
Claims16
A method of making a superconducting cable comprising:
- providing a plurality of wires at least one of which has at least one filament formed of a brittle superconductor;
- and
- intertwining the plurality of wires so that more than 50% of intimate contact surface areas between the wires are free of inter-wire bonds.
A method of making a superconducting cable comprising:
- providing a plurality of wires;
- intertwining the plurality of wires to form a cable;
- and
- reacting the plurality of wires to form at least one superconducting filament under conditions selected to produce a plurality of inter-wire bonds resulting in a predetermined degree of interwire bonding while leaving more than 50% of intimate contact surface areas between the wires free of inter-wire bonds.
A method of making a superconducting cable comprising:
- providing a plurality of wires at least one of which has at least one filament formed of a brittle superconductor;
- and
- intertwining the plurality of wires to form a cable so that a strain on the wires within the cable due to bending of the cable is essentially independent of a cross-sectional radius of the cable.
