High-temperature superconductor (HTS)-based flexible cabling systems for interconnecting components in two different cryogenic temperature zones

A high temperature superconductor (HTS)-based flexible cabling system configured to interconnect a first set of components in a first cryogenic temperature zone with a second set of components in a second cryogenic temperature zone, wherein the first cryogenic temperature zone has a temperature between 2 kelvin to 10 kelvin and the second cryogenic temperature zone has a temperature between 30 kelvin to 92 kelvin, the system comprising:

• a first HTS-based flexible cable arranged next to a second HTS-based flexible cable with at least one intervening spacer configured to maintain a fixed spacing between the first HTS-based flexible cable and the second HTS-based flexible cable,
• wherein each of the first HTS-based flexible cable and the second HTS-based flexible cable includes traces to define individual strips having a first strip width in a first region along a length of each of the first HTS-based flexible cable and the second HTS-based flexible cable and a second strip width, different from the first strip width, in a second region where the at least one intervening spacer is overlapping with a respective HTS-based flexible cable, and wherein each of the first HTS-based flexible cable and the second HTS-based flexible cable includes widened pads at respective ends;
• and
• a heat-transfer structure coupled to the at least one intervening spacer and a temperature-dependent thermal conductor.
