Multiphase coaxial superconducting cables and corc degaussing system

摘要

A superconducting cable and connection structure includes one or more superconducting cables. Each cable has superconducting tapes wound about a former in a plurality of phases. Superconducting tapes of a first phase extends further toward a distal end of each cable end than the superconducting tapes of the second phase. The first and second cable ends of one superconducting cable (or a first end of a first superconducting cable and a second end of a second superconducting cable) are arranged with the first phase of the second cable end electronically coupled to the second phase of the first cable end. Connector structures may couple the cable ends together. The cable(s) form one or more loops within a cryostat, to form a degaussing coil.

1. A superconducting cable and connection structure comprising:
a first superconducting cable end section having a plurality of superconducting tapes wound about a former in a plurality of phases, including a first phase and a second phase, the first phase is located closer to the former than is the second phase, the first phase extends further toward a distal end of the first superconducting cable end section than does the second phase; a second superconducting cable end section having a plurality of superconducting tapes wound about a former in a plurality of phases, including a first phase and a further phase, the first phase of the second superconducting cable end section is located closer to the former than is the further phase of the second superconducting cable end section, the first phase of the second superconducting cable end section extends further toward a distal end of the second superconducting cable end section than does the further phase of the second superconducting cable end section; wherein the first and second superconducting cable end sections are arranged with the first phase of the second superconducting cable end section electrically coupled to the second phase of the first superconducting cable end section, and with the further phase of the second superconducting cable end section being free of electrical contact at the second superconducting cable end section with each phase of the first superconducting cable end section at the first superconducting cable end section.
