Abstract

A method of fabricating second-generation high-temperature superconducting wires of a predetermined width involves the following stages: (A) fabrication of an HTS intermediate product for the production of HTS wires by sequential deposition of buffer layers, an HTS layer and a protective layer on the substrate tape; (B) slitting of the intermediate product of stage (A) in the longitudinal direction into HTS wires of a predetermined width. Each wire comprises at least one edge formed during slitting, with delaminated fragments adjoining said edge; (C) removing the delaminated fragments of the HTS wire obtained at stage (B); (D) applying an additional protective layer onto the wire of stage (C). The method makes it possible to retain the current carrying properties of an HTS wire after mechanical treatment, such as slitting, and to ensure predictability and stability of such properties.
