초록
The five-year national project in Japan for R&D of coated conductors and applications, named as the Materials and PowerApplications of Coated Conductors (M-PACC) project, was finished at the end of FY2013. The project consists of four sub-themesas cable, transformer, SMES and coated conductors. In the theme of coated conductors, the fabrication process had been developedto satisfy the requirements from the applications such as in-field Ic performance, low AC loss in the long tapes etc. Through theproject, the remarkable progress was achieved as follows; a high in-field minimum Ic value over 54A/cm-width under 3T at 77Kwas realized in a 200m long EuBCO tape with artificial pinning centers of BaHfO3 by the pulsed laser deposition (PLD) techniqueon the IBAD template. On the other hand, the AC loss reduction was confirmed in the tapes fabricated by both PLD and the metalorganic deposition (MOD) techniques by scribing 100m tapes into 10-filamments. Additionally, the mechanism of the delaminationphenomenon was systematically investigated and the strength was improved by eliminating the origins of the weak points in thefilms. Through the development, all targeted goals were accomplished and the several results were appreciated as a world championdata
