China appears to be building a large laser-ignited fusion research center in the southwestern city of Mianyang, experts at two analytical organizations say, a development that could aid nuclear weapons design and work exploring power generation.
Satellite photos show four outlying "arms" that will house laser bays, and a central experiment bay that will hold a target chamber containing hydrogen isotopes the powerful lasers will fuse together, producing energy, said Decker Eveleth, a researcher at U.S.-based independent research organization CNA Corp.
It is a similar layout to the $3.5 billion U.S. National Ignition Facility (NIF) in Northern California, which in 2022 generated more energy from a fusion reaction than the lasers pumped into the target: "scientific breakeven."
