48 tons of steel: Half the heart of SPARC fusion machine arrives

With the delivery of a key component — the first half of the vacuum vessel at the heart of our SPARC machine — our fusion energy plans are literally starting to take shape at Commonwealth Fusion Systems’ campus in Devens, Massachusetts.

This 48-ton half-donut-shaped steel construction is instrumental to SPARC’s mission to demonstrate the core technology for our ARC fusion power plant. We've already installed SPARC’s cryostat base, the foundation of a fusion machine called a tokamak, but the vacuum vessel gives a much better idea of SPARC’s final form and how it will carry us toward large-scale commercial fusion energy.
