TRANSCRIPT
One meter lengths of YBCO coated conductor have been fabricated by combining IBAD and PLD
Superconductivity Technology Center
Ion Beam Assisted Depositionproduces a textured YSZ layeron a polycrystalline base tape
Pulsed Laser Deposition is used for epitaxial growth of YBCO on the heated tape
Yttria-stabilized zirconia vapor
Ar ions
Moving tape (Inconel 625)

High-Temperature Superconducting Tape: materials system
Substrate - flexible polycrystallinemetal tape
Template layer -textured layer of IBAD YSZ or MgO
Buffer layer - epitaxial PLD CeO2
Superconductor - epitaxial PLD YBCO
Silver overcoat - for Environmental protection
Coated conductor layer sequenceis revealed by TEM cross-section
