Unlocking SPARC: HTS Magnet for Commercial Fusion Applications

An animation of how the high temperature superconducting (HTS) fusion magnet built by Commonwealth Fusion Systems (CFS) and MIT’s Plasma Science and Fusion Center (PSFC) was tested. Reaching a field of 20 tesla, it is the most powerful superconducting magnet in the world and a key technology in SPARC, a compact, high-field tokamak that will produce net energy from fusion.
