    "excerpt": "CFS delivers its first fusion magnet - a stronger, smaller design.\n\nCommonwealth Fusion Systems (CFS) has completed and delivered its first cutting-edge, superstrong magnet - a culmination of years of work to develop and manufacture the foundational technology to bring fusion energy to the grid.\n\nIn December, Commonwealth Fusion Systems LLC shipped the 24-ton steel-clad magnet across the CFS campus in Devens, Massachusetts, from its factory to its SPARC facility. It's now perched on an assembly stand where it'll become part of SPARC, the machine Commonwealth Fusion Systems LLC is building to demonstrate the core technology of a fusion power plant.\n\nAlthough it's only the first of 18 D-shaped toroidal field (TF) magnets Commonwealth Fusion Systems LLC need for SPARC, it's a big deal. It shows the maturity not just of this key technology but also of its company: Commonwealth Fusion Systems LLC has progressed from ideas to prototypes to initial manufacturing to full production.\n\n\"We didn't just make a single magnet. We made a whole manufacturing facility that can make many, many magnets,\" said CFS Chief Science Officer and Co-founder Brandon Sorbom. \"We learned how to set up a factory and run it at speed. Full steam ahead!\"\n\nThat operational excellence is crucial to CFS' long-term plans. Just as Commonwealth Fusion Systems LLC ramped up magnet manufacturing, Commonwealth Fusion...",
