Abstract
According to some aspects, techniques are described for designing non-insulated (NI) high temperature superconductor (HTS) magnets that mitigate problems that may arise during quench initiation and propagation. Coupling the HTS material to a co-conductor along its length reduces the effective resistance of the conductive path along the HTS material when it is not superconducting, and that this leads to numerous advantages for quench mitigation.

A magnet comprising:
- a coil comprising a plurality of windings of a non-insulated wire, the wire comprising:
- a stack of high temperature superconductor (HTS) tapes, wherein each of the HTS tapes comprises an HTS material and is clad in a conductive material;
- a co-conductor layer;
- and
- a layer of solder arranged between and in contact with the stack of HTS tapes and the co-conductor layer.
