Superconductive magnet coil arrangement with a plurality of layer-wound tape-shaped superconductors

摘要

A superconducting magnet coil assembly comprising a sheet wound, cylindrically symmetrical coil having a rectangular coil cross section in a cutting plane containing the axis of symmetry (z) and intersecting the coil, the coil cross section being defined by a radially inner and radially outer and an axially first and axially second coil edge defined by Position of a radially innermost and a radially outermost turn of the coil with the smallest or largest distance to the axis of symmetry, and by the position of an axially first and an axially last turn of the coil with the smallest or largest coordinate along the symmetry axis direction, wherein the coil and a second band-shaped superconductor (BL1, BL2) having an aspect ratio 3, and wherein the band-shaped superconductors are guided into and electrically connected to a region outside the coil cross-section, characterized in that the sp has: a first rectangular subregion (1; 1 '; 1 ";1"') within the coil cross section which completely covers the coil cross section along the symmetry axis direction and at least one second and third rectangular subregion (2; 2 '; 2 "; 3, 3 ', 3 ", 3"') within the first portion, the latter radially completely and axially partially overlap, wherein the second portion is completely wound with the first band-shaped superconductor and the third portion completely with the second band-shaped superconductor, and wherein the second and the third portion are disjoint, and that the band-shaped superconductors have different superconducting current carrying capacities at the same field, at the same field direction relative to the band plane and at the same temperature.
