Abstract
- REBCO coil is a promising technology for superconducting magnetic energy storage system (SMES). Although degradation has been discovered in epoxy impregnated coil, it is essential to fill the coil with epoxy in such occasion. This paper describes preparation of large scale epoxy impregnated REBCO coil for SMES. The coil with inner diameter 320 mm and 268 turns was tested at 77 K both before and after epoxy impregnation. Consistency of Ic value and high n-value suggest that there was no degradation in the coil. Conduction cooled test was also carried out. Transport current was run up to 223 A at 50 K.
