Abstract

jats:titleAbstract</jats:title> jats:pHigh temperature superconducting (HTS) conductors have become important candidates to be used in large-scale high-field magnets, owing to its high critical current density as well as good mechanical properties. At present, there are various forms of HTS conductors proposed. In this work, we reported the fabrication of the REBCO HTS coil using jats:italicin-situ</jats:italic> winding technology. The six-layer coil with a diameter of 410 mm achieved a total current of 2562 A, and generated a central magnetic field of 7.8 mT at 77 K. The stress, deformation, and defect caused during conventional winding procedure could be significantly decreased using jats:italicin-situ</jats:italic> winding technology, indicating it has great potential for the large-scale high-field magnets in next-generation fusion reactors.</jats:p>
