Energy to Power Solutions (e2P) of Tallahassee, FL is dedicated to the research and development (R&D) of applied superconducting systems. We present three separate R&D projects that e2P has participated in involving: a) High Temperature Superconducting (HTS) Superconducting Magnetic Energy Storage (SMES, b) HTS degaussing systems for naval ships, and c) HTS insert coils for neutron scattering experiments.

In a project sponsored by ARPA-E, e2P has design, fabricated and tested a sub-scale prototype HTS SMES using an HTS cable-in-conduit-conductor (CICC). The HTS CICC was fabricated using an “ITER-style” CICC fabrication process. The critical current (I_c ) versus compaction strain of the conduit was measured at liquid nitrogen. Test results show an unexpected peak in I_c at a compaction pressure around 1.5 % strain, with a rapid drop in I_c of the HTS CICC above 2% compaction strain. Other experimental results including I_c vs. bend diameter and twist pitch (i.e. torsional) strain are also presented.

In a separate project sponsored by the Office of Naval Research, e2P has designed, fabricated and tested a prototype 2-loop HTS degaussing systems used for ship protection. The 2-loop HTS degaussing cable passed a rigorous two-year ship qualification testing program and now fully qualified HTS protection systems are being installed on the USS Ft. Lauderdale (LPD-28), with three more HTS protection systems slated for installation on LPD-29, LP-30, and LPD-31.

Finally, e2P presents the design of an HTS insert coil for possible implementation in a neutron scattering experiment being conducted by the U.S. Department of Energy. The HTS insert coil will be initially tested in the background field of a 12-T horizontal split bore magnet at the MagLab in Tallahassee, FL. This unique high field test facility has the ability to apply a cyclical mechanical stress in order simulate the actual experimental conditions of the neutron scattering experiment.
