Title (EN) SUPERCONDUCTING WIRE
(FR) FIL SUPRACONDUCTEUR
Abstract:
(EN) A Type II superconducting filament is formed by surrounding a Type II superconducting alloy ingot core with layers of a fine grain Type II superconducting alloy, a refractory metal barrier layer disposed in a copper extrusion can (see figure 1). The composite is then reduced to a filament by hot and cold working. The multifilamentary wires exhibit superior critical current density.
(FR) On obtient un filament supraconducteur de type II, en entourant un noyau de lingot en alliage supraconducteur de type II par des couches d'un alliage supraconducteur de type II à grains fins, une couche barrière de métal réfractaire étant disposée dans une boîte d'extrusion en cuivre (voir figure 1). Le composite ainsi produit est ensuite réduit en un filament par travail à chaud et à froid. Les fils à multifilaments ainsi produits présentent une densité de courant critique supérieure.
