Achievements in M-PACC Project and Future Prospects on R&D of Coated Conductors in Japan

A national project of Materials & Power Applications of Coated Conductors (M-PACC) including R&D of coated conductors (CC) and the applications in Japan had been promoted for 5years and was finished at the end of February in 2013. In the R&D of coated conductors, the necessary specifications required from the applications were set as the targets and all of them were successfully achieved. Through the development, there were lots of remarkable results had been obtained, such as high in field Ic value of 54A/cm-width at 77K under 3T in 200m long tape, one-tenth of AC loss reduction in 100m long tape with 10 filaments etc. Although these achievements could make the lots of applications of coated conductors realize, further improvement is needed to obtain an absolute advantages to competitive technologies. Based on this situation, the development should be continued to have the coated conductors with much higher specifications, which is called as 3rd generation wire.
