Outline of Final Research Achievements |
We have investigated current transport property of REBCO coated conductors over a wide range of temperature (4.2K to 77K) & external magnetic field (self-field to 27T) and expressed it by using our proposed model based on a percolation transition model and scaling law of macroscopic pinning force density. Moreover, we confirmed in-field critical current at low temperature can be predicted from that at liquid nitrogen temperature by choosing certain conditions of magnetic field. These results are useful and effective not only for optimal design of electric power devices but also for feed-back to production of REBCO coated conductors.
