BNL magnet division carried out R&D on the design, construction, and testing of a 25 T, 100 mm solenoid made with the High Temperature Superconductors (HTS) operating at 4 K. This work was carried out during the years 2011 to 2014 as a part of devloping a Superconducting Magnetic Energy Storage (SMES) system. This ambitious task was in line with the ARPA-E’s mission to catalyze and accelerate the creation of transformational energy technologies by making high-risk, high-reward investments in their early stages of development. As a part of this R&D, BNL demonstrated a high field HTS solenoid reaching 12.5 T at 27 K, a world record at that time, which played a role in dreaming nuclear fusion devices operating in similar parameter range in coming years.
Contributions of the Magnet Division at BNL are summarized below. This work was supported in part by the DOE Advanced Research Program Agency-Energy via a Cooperative Research and Development Agreement that Brookhaven National Laboratory (BNL) has with ABB, Inc. and in part by the Brookhaven Science Associates, LLC (BSA) under Contract DE-SC0012704 with the U.S. Department of Energy.
