Abstract

Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3O10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a–b planes of the superconductor. The fabrication process we propose allows the preparation of long conductors in which the filaments can be inclined with respect to the plane of the tape, according to the magnetic flux profile. Such tapes can be useful in a variety of applications, as for the outer parts of high field superconducting magnets, where the flux lines present large angles with respect to the conductor plane.

Magnetic field

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.

Superconducting magnet

A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce stronger magnetic fields than all but the strongest non-superconducting electromagnets, and large superconducting magnets can be cheaper to operate because no energy is dissipated as heat in the windings.

Technological applications of superconductivity

Technological applications of superconductivity include: the production of sensitive magnetometers based on SQUIDs (superconducting quantum interference devices) fast digital circuits (including those based on Josephson junctions and rapid single flux quantum technology), powerful superconducting electromagnets used in maglev trains, magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) machines, magnetic confinement fusion reactors (e.g.
