Abstract

A peelable superconductive conductor comprising a superconductive conductor including a substrate and a superconducting layer which is formed on one principal surface of the substrate. The peelable superconductive conductor can further comprise a peelable carrier body, which is formed on a principal surface of the superconductive conductor on an opposite side of the surface on which the superconducting layer is formed.

the metal substrate and the carrier body are partially joined by swaging.

4. The peelable superconductive conductor according to claim 1 , wherein,
the substrate includes a metal substrate; and
a thickness of the metal substrate is 50 μm or less.

5. A production method of a peelable superconductive conductor comprising:
forming a peelable carrier body on one principal surface of a substrate; and
forming a superconducting layer on a principal surface of the substrate on an opposite side of the surface on which the carrier body is formed.

6. The production method of the peelable superconductive conductor according to claim 5 , wherein, the carrier body is made from a material which is same as the substrate.

7. A production method of a peelable superconductive conductor comprising:
forming a handling carrier body on one principal surface of a substrate;
forming a superconducting layer on a principal surface of the substrate on an opposite side of the surface on which the handling carrier body is formed;
removing the handling carrier body; and
forming a peelable carrier body on the principal surface on a side from which the handling carrier body is removed.

8. The production method of the peelable superconductive conductor according to claim 7 , wherein,
the handling carrier body and the substrate include a partially joined joint; and
the joint is removed in the removing of the handling carrier body.

9. A repair method for a superconducting wire comprising:
preparing a peelable superconductive conductor in which a superconducting layer is formed on one principal surface of a substrate and a peelable carrier body is formed on an other principal surface;
specifying an Ic deteriorated portion of a superconducting wire including the Ic deteriorated portion in a portion of the superconducting wire;
removing the carrier body from the peelable superconductive conductor; and
electrically connecting the peelable superconductive conductor with the carrier body removed to the superconducting wire so as to cover the Ic deteriorated portion.

10. A repair method for a superconducting wire comprising:
preparing a peelable superconductive conductor in which a superconducting layer is formed on one principal surface of a substrate and a peelable carrier body is formed on an other principal surface;
specifying an Ic deteriorated portion of a superconducting wire including the Ic deteriorated portion in a portion of the superconducting wire;
electrically connecting by positioning the peelable superconductive conductor with the superconducting layer facing each other so as to cover the Ic deteriorated portion; and
removing the carrier body from the peelable superconductive conductor.
