Materials Science of High-Temperature Superconducting Coated Conductor Materials

This program was broadly focused on the materials science of high temperature superconducting coated conductors, which are of potential interest for application in electric power systems of interest to the Air Force. The three main elements of the program were as follows 1 understanding the basic materials science underlying the deposition of 123 YBCO at the high rates needed for economic manufacture of coated conductors 2 exploration of variants of and alternatives to 123 YBCO for possible application as coated conductors and 3 in the early parts of the program development and application of in situ deposition process monitoring tools relevant to coated conductor deposition. Each of these topics is discussed in turn. In addition, other topics are addressed as special opportunities that presented themselves as the program evolved.
