Abstract: Abstract Rare-earth-barium-copper-oxide (REBCO) coated conductors are promising conductors for high energy and high field superconducting applications. In the case of epoxy impregnated REBCO superconducting pancake coils, however, excessive radial tensile stress generated in the winding… read more here.
