M.W. Rupich     AMSC, Devens, MA, USA

Abstract

More than two decades after the discovery of high-temperature superconductivity, superconducting wires, based on the YBaCuO family of materials, are finally being manufactured with the performance necessary for use in initial commercial applications. The development of these second-generation (2G) high-temperature superconductor wires required overcoming formidable scientific, engineering, and manufacturing challenges. This chapter summarizes the technical challenges that were addressed in the development of 2G wire technology, describes the multiple approaches used for manufacturing today's ...
