摘要：

Second-generation coated conductor composite HTS wires have been fabricated using a continuous reel-to-reel process with deformation-textured Ni-W substrates and a metal-organic deposition process for YBa2Cu3O7-x. Earlier results on 1 m long and I cm wide wires with 77 K critical current performance greater than 100 A cm(-1) width have now been extended to 7.5 m in length and even higher performance, with one wire at 132 and another at 127 A cm(-1) width. Performance as a function of wire length is remark-ably uniform, with only 2-4% standard deviation when measured on a 50 cm length scale. The length-scale dependence of the deviation is compared with a statistical calculation.
