Title (EN) COMPONENT AND METHOD FOR FABRICATING SUPERCONDUCTING WIRE
(FR) COMPOSANT ET PROCEDE DE FABRICATION D'UN FIL SUPRACONDUCTEUR
Abstract: front page image
(EN)A component (10) for making A15 Nb¿3?Sn superconducting wire is of plane-filling cross-section after removing temporary additions (6, 7). It consists of a central pillar (1) of aluminium (later replaced by tin) surrounded by a two-deep array of polygonal copper columns (2/2a) containing niobium rods. Many (e.g. 61) components (10) are stacked together and extruded. The niobium rods adopt and retain a uniform distribution with minimum intervening material. On heat-treatment of the whole, the tin diffuses over a relatively short path and hence consistently into the rods, whereby there is formed a kilofilament Nb¿3?Sn wire.
(FR)Un composant (10) servant à fabriquer un fil supraconducteur A15 de Nb¿3?Sn présente une coupe transversale pleine après que l'on ait enlevé des additions temporaires (6, 7). Elle se compose d'une colonne centrale (1) d'aluminium (plus tard remplacé par de l'étain), entourée par un agencement de colonnes de cuivre polygonales en une profondeur de deux colonnes, (2/2a), contenant des tiges de niobium. Plusieurs de ces composants (10) (par exemple 61), sont empilés ensemble et extrudés. Les tiges de niobium adoptent et retiennent une distribution uniforme avec un minimum de matériau intercalaire. Lors du traitement thermique de l'ensemble, l'étain se diffuse sur une distance relativement courte et de manière consistante dans les tiges, ce qui permet de produire un fil de Nb¿3?Sn d'un kilofilament.
