Title: LONG LENGTH HIGH TEMPERATURE SUPERCONDUCTING WIRES WITH UNIFORM ION IMPLANTED PINNING MICROSTRUCTURES
Abstract:
A method for producing a long length high temperature superconductor wire is proposed which includes irradiating a biaxially textured high temperature superconductor layer formed on a substrate having a length of at least 50 meters with an ion beam impinging uniformly along the length and across the width of the superconductor layer to produce a uniform distribution of pinning microstructures therein. Preferably, a REBCO coated conductor tape is irradiated with Au ions in a reel-to-reel apparatus.
