Superconducting connection between MgB2 superconducting wires via a compressed element made from HTS powder
Abstract:
A method for connecting two or more superconducting wires (1, 2), each comprising at least one filament (3a-3b) that contains MgB2, wherein the superconducting connection is realized through exposed end regions (13) of the filaments (3a-3d) via a superconducting matrix, is characterized in that a bulk powder (4) of a high-temperature superconductor (HTS) powder with a transition temperature of Tc>40K is provided, into which the exposed end regions (13) of the filaments (3a-3d) project, wherein the Boron of the Boron powder of the bulk powder (4) is in amorphous modification, and the bulk powder (4) is compacted together with the projecting exposed end regions (13) of the filaments (3a-3d) to form a compressed element (8). The method improves the quality, in particular, the current carrying capacity and the critical magnetic field strength of a superconducting connection of two MgB2 wires.
