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 YBa 2 Cu 3 O 7−x . Earlier results on 1 m long and 1 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 remarkably 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
