Abstract
Official abstract text for this publication.
A method of manufacturing an HTS coil is provided. The method comprises winding an HTS coil cable to produce a coil having a plurality of turns. During winding of a turn of the coil, one or more HTS shunt cables are placed adjacent to the previous turn of the coil along a first arc of the coil, and then the turn is wound such that the HTS shunt cable is sandwiched between the turn and the previous turn of the coil such that current can be shared between the HTS shunt cable and the HTS coil cable.
First claim
Opening claim text (preview).
The invention claimed is: 1. A high temperature superconducting, HTS, coil comprising: an HTS coil cable comprising HTS tapes, and arranged to form a spiral having a plurality of turns; one or more HTS shunt cables comprising HTS tapes, each HTS shunt cable being arranged between a respective pair of adjacent turns, along a first arc of the coil, such that the HTS coil cable and at least one side of the HTS shunt cable are electrically connected, and such that HTS tapes of the HTS shunt cables are parallel with HTS tapes of the HTS coil cable. 2. An HTS coil according to claim 1 , and comprising a plurality of HTS shunt cables arranged along the first arc of the coil, each arranged between a respective pair of adjacent turns. 3. An HTS coil according to claim 1 , wherein the or each HTS shunt cable is in electrical contact with the HTS coil cable on both sides of the HTS shunt cable. 4. An HTS coil according to claim 1 , wherein the HTS coil cable and/or each HTS shunt cable each comprise a stack of HTS tapes arranged such that HTS layers of the HTS tapes are parallel. 5. An HTS coil according to claim 1 , and comprising further components which are one or more of: heaters; temperature sensors; magnetic field sensors; spacing elements; metallic stabilizer, such as copper, brass or steel alloy; and coolant channels; arranged between respective pairs of adjacent turns of the HTS coil cable. 6. An HTS coil according to claim 5 , wherein the further components are arranged along a second arc of the coil which does not overlap with the first arc. 7. An HTS coil according to claim 1 , and comprising spacing elements arranged between respective pairs of adjacent turns of the HTS coil cable, wherein the width of the spacing elements varies around the coil.
