摘要：

We have developed an ion-beam-assisted-deposition (IBAD) and a pulsed-laser-deposition (PLD) technique to produce REBa2Cu3Ox (RE123, RE: rare earth) coated conductors with high performances. Distributions of critical currents (I-c) in the longitudinal direction were improves in most wires routinely fabricated under optimized process. A typical wire showed I-c of 460 A/cm at 77 K and self-field, about 200 A/cm at 65 K and 3 T and about 300 A/cm at 50 K and 5 T. In addition, further high I-c values over 800 A/cm were also obtained in thick films. Finally, we succeeded in fabricating an 816.4 m long wire with end-to-end I-c of 572 A/cm, corresponding to the new world record I-c x L value of 466,981 A/cm. (C) 2012 Published by Elsevier B.V.
