Second Generation (2G) High Temperature Superconducting (HTS) wire based on the YBCO coated conductor is being developed for new military and commercial applications not accessible to First Generation (1G) HTS wires. Although a critical current (Ic) of nearly 300A/cm-w (77K, sf) has been obtained in 10-meter lengths of 2G conductors, significant improvement in the Ic of practical conductors is required before they are useful for the targeted applications. We propose in this Phase I program to demonstrate a scalable, thick-film MOD technology to achieve Ic's >450A/cm-w (77K. sf) in practical 2G conductors. Our approach is based on understanding of the relationship between film properties, microstructure and processing. During the Phase I program, the through thickness properties of the YBCO will analyzed and used to optimize precursor and processing conditions. The proposed program will focus on producing YBCO films with Ic's >450 A/cm-w (77K, sf) and >150A/cm-w (65K, 3T) using materials, processes, and equipment compatible with AMSC's 2G manufacturing line. The Phase II program will focus on: (1) incorporation of the high Ic, technology into AMSC's 2G pilot manufacturing facility and (2) the manufacture and delivery of high Ic 2G wire for testing and demonstrating in critical military applications.
