Abstract:
1. A high-temperature superconductor (HTS) coil, comprising: at least one coil winding comprising a superconducting material, a coil former for carrying the at least one coil winding, wherein, when the high-temperature superconductor (HTS) coil cools down from a room temperature to an operating temperature, the coil winding or the coil former counteract a thermal shrinkage of the at least one coil winding in order to avoid or reduce a longitudinal compression of the superconducting material of the at least one coil winding, wherein a thermal shrinkage of the insulation sheath is less than a thermal shrinkage of the impregnating material when the (HTS) coil cools down to the operating temperature.
