YBCO Coated Conductor Development by Non-Vacuum Chemical Processes

The primary focus of the research was to use magneto optical imaging (MOI) to further our understanding of HTS materials. One particular focus was the use of MOI with in-situ tensile straining to image the effects of mechanical strain on the magnetization, which relates to the current carrying capacity of the conductor. To support the analysis of the MOI imaging, and to convert the results from being qualitative to quantitative, techniques were also developed to interpret the image intensities. Scanning electron microscopy was also used to support the MOI research.
