Abstract

Techniques are described for lowering strains applied to superconducting material in a superconducting magnet by arranging structural partitions between turns of the superconducting material that intercept and transfer strain to a mechanically stronger structure, such as the housing of the magnet. A structural partition may be formed with a feedthrough slit so that the superconducting material can easily pass through the partition. A number of structural partitions may be interspersed between groups of turns of superconducting material in a magnet so that forces can be sufficiently distributed by the partitions throughout the magnet. At the same time, the number of structural partitions may be selected to minimize the amount of space within the magnet occupied by the partitions that could otherwise be occupied by current-carrying superconducting material.

Claims (33)

1 . A high temperature superconductor (HTS) magnet comprising:

a coil comprising HTS material; a housing comprising at least a first partition having a feedthrough slit provided therein, wherein: the coil is arranged within the housing,

2 . The magnet of claim 1 , wherein the housing comprises a first structural plate and a second structural plate, wherein the coil is arranged between the first and second structural plates, and wherein the first partition comprises a wall extending between the first and second structural plates.

3 . The magnet of claim 2 , wherein the first structural plate comprises a first slot, and wherein the first partition is arranged within the first slot.

4 . The magnet of claim 1 , wherein the feedthrough slit extends through the height of the first partition.

5 . The magnet of claim 1 , wherein an outer dimension of the first partition is a spiral shape, and wherein the feedthrough slit of the first partition is a gap between adjacent turns of the spiral shape of the first partition.

6 . The magnet of claim 1 , wherein the HTS material is HTS tape.

7 . The magnet of claim 6 , further comprising an electrically conducting material arranged between at least some turns of the coil.
