Embodiment Construction

[0039] Identical parts are denoted by the same reference numerals in the various figures.

[0040] figure 1 The shown superconductors are based on known embodiments. In this case, both so-called monocore superconductors and multifilament superconductors as shown in the drawing can be involved. Such a superconductor 2 has a plurality of superconducting conductor leads or wires 3i embedded in a matrix 4, which consists of a normally conducting material. All known low-temperature or high-temperature superconducting materials can be used as material for the conductor leads 3i, such as NbTi, Nb 3 Sn, MgB 2 , YBa 2 Cu 3 o x or (Bi, Pb) 2 Sr 2 Ca 2 Cu3 o y . Known materials for the matrix are either elements (eg Cu, Ni, Ag, Fe, Wo, Al) or alloys, in particular alloys of these elements (eg CuNi, AgMg, CuSn, CuZn or NiCr).

[0041] In order to be able to make low-resistance contacting of at least two end pieces of a corresponding multifilament superconductor or single-core ...

Abstract

In a superconductive connection (10) for two end pieces (12, 22a) of superconductors (12, 22) that each have a matrix of normally-conductive material and at least one superconductor lead (13, 23), of superconductive material, in the matrix, and in a method for making such a superconductive connection, the respective end pieces (12a, 2a) of the conductor leads (13, 23) are stripped of the matrix material and are inserted into the connecting area of sheath or bushing (6). MgB2, as superconductive contacting material (7), is additionally inserted into the sheath or bushing, so as to at least partially fill regions in the sheath or bushing between the conductor leads (13, 23). The cross-section of the sheath or bushing (6) is then reduced for establishing the connection (10).

Description

technical field [0001] The invention relates to a superconducting connection or a superconducting connection between the end pieces of at least two superconductors, each having a matrix made of a normally conducting material and at least one conductor lead made of a superconducting material, wherein , in the connection zone in the bushing or sleeve, [0002] - the conductor leads of the end piece are arranged in such a way that the matrix material is at least partially removed, and [0003] - There is also a superconducting contact material, which is located at least in the region between the conductor leads. [0004] A corresponding superconducting connection and a method for producing such a connection are available from DE 34 13 167 A1. Background technique [0005] Using LTC (low critical temperature, Low-T c ) superconducting material or HTC (high critical temperature, High-T c ) Superconductors of superconducting materials are usually made into single-core conducto...
