Abstract
A method for arranging a superconductor cable including the step of laying the superconductive cable core into a cryostat with an overlength in comparison to the axial length of said cryostat. After laying the superconductive cable core, it is cooled to its operating temperature thereby shortening the superconductive cable core relative to the cryostat. After cooling the superconductive cable core, the shortened superconductive cable core is mechanically fixed at its two ends to the ends of the cryostat. After fixing the shortened superconductive cable core, terminations are mounted on the ends of the cable core, such that if the superconductive cable core heats up, the core deforms into a wave or helix inside the cryostat, with the length change that acts on components of the superconductor cable being negligible.
