説明
We have developed high critical current, Ic, and long GdBa2Cu3O7-X (GdBCO) coated conductors using ion-beam assisted deposition (IBAD) / multi-plume and multi-turn pulsed laser deposition (MPMT-PLD) method. We have successfully fabricated 32 and 60.7 m long GdBCO coated conductors with high Ic of 205 and 183 A at 77 K and 0 T, respectively. Moreover, the Ic of the 32 m long GdBCO coated conductor exceeded 20 A at all angles for the applied magnetic field of 3 T. This Ic value at 3 T was 2.5 times higher than that of the 200 A class YBa2Cu3O7-X(YBCO) coated conductor. The production rate of the GdBCO layer was 7.5 to 10 m/h, which is about 2.6 times faster than that for a YBCO layer using the MPMT-PLD method and 10 times faster than that for a YBCO layer using the conventional PLD, single-plume and single-turn PLD, method. In addition, the material yield of the GdBCO layers using the MPMT-PLD method was about 26 to 28%. The GdBCO coated conductors with a high Ic in the magnetic field at 77 K, and capable of being produced quickly and with a high material yield are promising for practical applications.
