Title
(EN) JOINT HIGH TEMPERATURE SUPERCONDUCTING COATED TAPES
(FR) SUPRACONDUCTEURS A HAUTE TEMPERATURE PERFECTIONNES
Abstract
(EN) This invention relates to a practical superconducting conductor based upon biaxially textured high temperature superconducting coatings. In particular, methods for producing flexible and bend strain-resistant articles and articles produced in accordance therewith are described which provide improved current sharing, lower hysteretic losses under alternating current conditions, enhanced electrical and thermal stability and improved mechanical properties between otherwise isolated films in a coated high temperature superconducting (HTS) wire. Multilayered materials including operational material which is sensitive to bend strain can be constructed, in which the bend strain in the region in which such operational material is located is minimized. The invention also provides a means for splicing coated tape segments and for termination of coated tape stack ups or conductor elements. In one embodiment, a multi-layer high temperature superconductor is provided and includes first and second high temperature superconductor coated tape elements (11a, 11b). Each element includes s substrate (12a, 12b), at least one buffer (14a, 14b) deposited on the substrate, a high temperature superconductor layer (16a, 16b) and a metallic cap layer (18a, 18b). The first and second high temperature superconductor coated elements are joined at the first and second cap layers using soldering, diffusion bounding or the like.
(FR) L'invention concerne un supraconducteur pratique recouvert de revêtements supraconducteurs orientés bi-axialement. D'une manière spécifique, l'invention concerne des procédés permettant de produire des articles flexibles et résistants à la contrainte de flexion et également des articles ainsi produits qui permettent d'obtenir un meilleur partage de courant, des pertes par hystérésis moindres dans des conditions de courant alternatif, une meilleur stabilité électrique et thermique ainsi que de meilleures propriétés mécaniques entre des films qui, autrement, sont isolés dans un fil supraconducteur à haute température (HTS) revêtu. Il est possible de construire des matières multicouches comprenant des matières fonctionnelles sensibles à la contrainte de flexion, dans laquelle la contrainte de flexion de la région dans laquelle se trouve ladite matière fonctionnelle est minimisée. L'invention concerne également un dispositif permettant d'épisser des segments de bande revêtue et de terminer des piles de bande revêtue ou d'éléments conducteurs. Dans un mode de réalisation, un supraconducteur multicouche à haute température comporte un premier et un second éléments supraconducteurs revêtus à haute température. Chaque élément comprend un substrat, au moins un tampon déposé sur le substrat, une couche supraconductrice à haute température et une couche d'encapsulation. Le premier et le second éléments supraconducteurs à haute température revêtus sont épissés au niveau de la première et de la seconde couche d'encapsulation.
