Scientific Presentations on Superconductivity from 2002-2005
Abstract
This program addresses the basic scientific and engineering issues related to the development of the second-generation high-temperature superconducting (HTS) coated conductor for use in magnet and generator coil windings of power applications relevant to the Air Force (AF). Current work focuses on the development of an ac YBCO-coated conductor and enhancement of the current dc coated conductor. The dc coated conductor development is done as part of an overall AF program that includes industry and academic research facilities. This program is coordinated with the Department of Energy's Coated Conductor Program to ensure integration with no redundancy. Flux pinning in the conductor is a significant focus of the overall coated conductor work to improve in-field critical currents. The ac loss issues as well as stability (and quench protection) ultimately must be considered for study, and work has commenced in this area within the in-house program. In order for the conductor to be ready for projected power generation requirements (for directed energy weapons), the superconductivity group is determining the unique AF requirements of the conductor and investigating ac loss and flux pinning issues.
