    • A large diameter, high current capacity, superconductive solenoid coil is formed by winding a conductor around a cylindrical mandrel 2, and then encasing the outer surface of the coil 1 with a support cylinder comprising an assembly of cylinder sectors 11 rigidly joined together along axial seam lines. The joining of the sectors may be implemented by welding, and heat shielding strips 13 may be disposed in recesses 15 in the sectors to prevent thermal damage to the coil insulation 14 during the welding. The support cylinder serves to absorb heat generated during the operation of the coil, and to withstand the outwardly directed electromagnetic forces developed. The mandrel is removed after the cylinder sectors are joined.
    • 通过将导体围绕圆柱形心轴2缠绕而形成大直径,高电流容量的超导电磁线圈,然后用包括沿着轴向接缝刚性地连接在一起的气缸扇区11的组件的支撑圆筒包围线圈1的外表面 线条。 扇区的接合可以通过焊接实现,并且热屏蔽带13可以设置在扇区中的凹部15中,以防止在焊接期间对线圈绝缘体14的热损伤。 支撑筒用于吸收在线圈操作期间产生的热量并且承受所产生的向外导向的电磁力。 在圆柱体部分连接之后,心轴被移除。
