Topological Fusion of Magnetic Mirror and Stellarator: How Fu Guoyong's Team's "Linked-Mirror" Deduces a New Engineering Pathway for Controlled Nuclear Fusion

After decades of fundamental theoretical exploration and engineering trial and error, global controlled nuclear fusion is accelerating into the deep waters of commercial validation. Faced with the engineering limits of the Tokamak approach under extreme parameters and the manufacturing complexity ceiling confronting traditional Stellarators, Chinese research teams are opening a new pathway that combines physical feasibility with engineering economy. Recently, the team led by Fu Guoyong, Professor at the School of Physics of Zhejiang University, Director of the Zhejiang University Fusion Theory and Simulation Center, and Founder of Jingjie Fusion Energy, officially released on the preprint website arXiv a research paper titled "A Novel Linked-Mirror Device for Fusion." Through three-dimensional numerical computation, the study obtained for the first time equilibrium solutions of the Linked-Mirror configuration under finite Beta (the ratio of plasma pressure to magnetic pressure) conditions. This breakthrough marks a decisive step for this technical pathway from a purely theoretical concept toward an engineering validation device.
