Abstract
A composite superconducting wire using ceramic superconductor material in which one or more elongated superconductor material are accommodated in one or more grooves formed on an elongated reinforcing member so that a long size superconductor wire can be provided. Various methods of producing such composite superconductor wire are also disclosed.
Claims8
A method for the production of a composite superconducting wire comprising in sequence:
- (a) a step of installing a composite oxide or composite ceramic superconductor wire in a groove of an elongated reinforcing member, said groove extending in a longitudinal direction of said reinforcing member;
- (b) a step of covering said reinforcing member with the superconductor wire installed in said groove with an outer pipe;
- (c) a step of drawing said reinforcing member covered with said outer pipe to obtain an elongated superconductor wire;
- and
- (d) a step of performing thermal treatment of said elongated superconductor wire with said outer pipe supplying necessary elements from one end of the outer pipe.
- (e) a step of removing said outer pipe from said drawn superconductor wire;
- and
- (f) a step of performing thermal treatment of said elongated superconductor wire with said outer pipe removed.
