摘要：

Tapes of 30-m length high-J(c) Y-123 were processed by using ion-beam-assisted deposition (IBAD) and pulsed-laser deposition (PLD). Biaxially textured Gd2Zr2O7 buffer layers up to 60-m length were fabricated by IBAD with production speed of 0.5-1.0 m/h. Y-123 films were processed on them by PLD with production speed of 1.0-4.0 m/h. A 30-m Y-123 film was obtained with uniform thickness of 0.5 mum and Deltaphi of 8-11degrees. I-c of 49 A (J(c) = 0.99 MA/cm(2)) was obtained in 10-m length part end-to-end, whose I-V curve had high n-value of 46. The 30-m length end-to-end I-c value was 40 A (J(c) = 0.8.MA/cm(2)), where I-c times length reached 1200 Am.
