Abstract
This Phase I Project will produce RABiTS-based YBCO CCs which are suitable for the manufacture of YBCO Coated Conductors with reduced AC losses. The improvements are based on a novel approach in the production of elements of the conductor. Anticipated AC losses will be analyzed for magnetic field and frequency conditions resembling those experienced by synchronous generator windings and air core transformers. The improved substrates and the implications of the analysis will be included in further Coated Conductor production, scale-up, process optimization and CC design in the Phase II. The proposed work will lead to significant improvements in YBCO Coated Conductors allowing usage in generators and transformers that experience relatively high magnetic fields and enhanced frequencies.
