Long length of high temperature superconducting wire with uniform ion implanted pinning microstructure

摘要

A biaxially textured high temperature superconductor layer formed on a substrate having a length of at least 50 meters into an ion beam uniformly impinging across the width of the superconductor layer to create a uniform distribution of the pinning microstructure therein. A method for producing a long length of high temperature superconducting wire, comprising the step of irradiating, is proposed. Preferably, the REBCO coated conductor tape is irradiated with Au ions in a reel to reel device.
