HTS Degaussing Cable

High Temperature Superconducting (HTS) cables offer major advantages over the conventional copper cables currently used to reduce the magnetic signatures of Navy ships. A degaussing system utilizing HTS cables would be smaller, lighter, and cost less to install than current systems. However, new components, cables, and connection technologies are needed before HTS systems can be considered for installation and operation in Navy ships. In particular, there are no suitable HTS cables currently available for this application. HTS cables being developed for electricity transmission have different voltage, insulation, and cooling requirements. Creare is pursuing a development program to provide the Navy with the technology needed to transition an HTS Degaussing System into the next generation of warships. As part of this development effort, we propose to develop an innovative HTS degaussing cable, in which up to 40 HTS conductors are installed in a flexible cryostat that is terminated with quick disconnect couplings. In Phase I of this project, we will develop a cable design and demonstrate that it will meet the Navy’s requirements for this system. In Phase II we will fabricate full-length prototype cables using production fabrication techniques and demonstrate their performance in a degaussing system.
