Abstract
Long YBa2Cu3Ox (Y-123) coated tapes were produced by reel-to-reel continuous processes using Ion-Beam-Assisted Deposition (IBAD) and Pulsed-Laser-Deposition (PLD). Biaxially textured Gd2Zr2O7 buffer layers up to 255 m long were fabricated by IBAD with the production speed of 0.5-1.0 m/h. Y-123 films were formed on them by PLD with the tape speed of 1.0-4.0 m/h. A 105 m long Y-123 film was formed with the uniform thickness of 1.0 μm and the ÎÏ of 3-4°. The end-to-end Ic of 126 A was achieved at 77 K, 0 T, whose I-V curve had the n-value of 28.5. The Ic times length reached 13,230 Ã
. Another 70Â m long Y-123 tape with the Ic of over 90Â A (77Â K, 0Â T) was wound into a solenoid type magnet whose inner diameter was 60Â mm. The central magnetic field of 0.082Â T was obtained at 77Â K, with operating current of 42Â A and that of 0.27Â T was obtained at 66Â K, with operating current of 130Â A.
