High critical current density YB+CU,O,-~ (YBCO) tapes were fabricated by epitaxial dep on roiling-assisted-biaxially-textured-substrates (RABiTS). The RABiTS technique uses well established, industrially scaleable, thermomechanical processes to impart a strong biaxial texture to a base metal. This is followed by vapor deposition of epitaxial buffer layers to yield chemically and structurally compatible surfaces. Epitaxial YBCO films grown on such substrates have critical current densities

Deposited conductors made using this technique offer a potential route for the fabrication of long lengths of high J, wire capable of carrying high currents in high magnetic fields and at elevated \ temperatures.
