CFS Advances Fusion Tech with Magnet Supply Deal
Commonwealth Fusion Systems Sends Specialized Magnets to University of Wisconsin-Madison
Commonwealth Fusion Systems (CFS) is advancing the fusion sector by sending two specialized magnets to the University of Wisconsin-Madison, marking a shift toward supply agreements in addition to traditional R&D partnerships. CFS CEO Bob Mumgaard highlighted the company’s commitment to collaboration, noting the magnets’ versatility and potential to support other fusion projects. This initiative precedes the launch of CFS’s SPARC demonstration reactor and represents a significant step in the company’s development.
Supported by over $2 billion in venture funding, CFS has developed a unique rare earth barium copper oxide (REBCO) magnet with MIT, allowing for smaller, more powerful magnets crucial for containing the plasma needed for fusion reactions. The University of Wisconsin-Madison’s WHAM reactor, different from CFS’s tokamak, will use these magnets for research funded by the federal ARPA-E program. Although CFS is not sharing its technology with direct competitors, this partnership aims to strengthen the broader fusion research community, providing magnets, assemblies, cooling, and control systems managed by CFS’s software. Mumgaard emphasized the mutual benefits and financial returns from the significant investment in magnet development.
