Overview
- Realta Fusion and Commonwealth Fusion Systems announced a long-term deal for CFS to design and build high‑temperature superconducting magnets for Realta’s magnetic mirror reactors.
- The companies said the agreement could reach a multi‑billion‑dollar value and includes CFS talent working alongside Realta on design, manufacturing, and operations.
- CFS called it its largest magnet deal to date, framing it as part of a plan to sell or license its magnet technology to other projects, including Type One Fusion.
- Company leaders said construction of CFS’s SPARC tokamak is about 70% complete, and the magnet work for Realta will keep its specialized factory busy between CFS milestones.
- The partnership builds on the WHAM experiment at the University of Wisconsin, where CFS magnets helped confine plasma at a 17‑tesla field in 2024, giving Realta a tested path to scale.
