Outline of Final Research Achievements

The REBCO high-temperature superconductor, which has been progressed towards practical use, enables superconducting coil systems with very high current density. Such a high-current density REBCO coil, however, can be damaged due to thermal unexpected thermal runaway and remedies against thermal runaway have to be developed for practical application. In this study, the effect of no-insulation method on REBCO coils was investigated for protection from thermal runaway.
