Shaped superconducting magnetic coil

摘要

Double pancake coils include a pair of pancake coils of different outer dimensions, and are wound from the same continuous length of superconducting wire. The double pancake coils are coaxially positioned and electrically interconnected along a longitudinal axis to provide a multi-coil superconducting magnetic coil assembly. Each of the double pancakes has at least one of its pancake coils electrically connected to at least another pancake coil of an adjacent double pancake coil having substantially the same outer dimension. The electrical connections between adjacent pancake coils are provided with relatively straight or "unbent" segments of superconducting wire even though the outer dimension profile of the superconducting magnetic coil assembly along its longitudinal axis varies.
