This Special Issue of the IEEE Transactions on Applied Superconductivity is a collection of six papers focusing on the SPARC Toroidal Field Model Coil (TFMC) Program, a collaboration between the Massachusetts Institute of Technology Plasma Science and Fusion Center (MIT PSFC), a leader in high-field magnet development for decades, and Commonwealth Fusion Systems (CFS), a company spun out from the MIT PSFC with the objective of commercializing fusion as an energy source. This three-year effort between 2018 and 2021 had the goal of designing, building, and testing a first-in-class, high-field (∼20 T), representative fusion-scale (∼3 m) superconducting toroidal field coil made with the high-temperature superconductor (HTS) Rare Earth Barium Copper Oxide (REBCO). The TFMC was a prototype for establishing the technology now being integrated into the toroidal field magnet of the SPARC tokamak, a net-energy magnetic fusion device currently under construction in Devens Massachusetts at CFS. The progress made as part of this program is a significant step forward in demonstrating high-field HTS magnet technology as an enabler of the high magnetic field pathway to compact, net-energy fusion machines.
