Civil engineering completed on Iter’s tokamak building

Complex will house the “biggest fusion device of our time” at research facility in France

Civil engineering work has been completed on the building that will house the “biggest fusion device of our time”—the ‘tokamak’ machine that will be used to control plasma at the International Thermonuclear Experimental Reactor fusion research facility being built in France.

The teams responsible for the 60-metre-high Iter Tokamak complex have signed off the work, which involved more than 7 million person-hours over the past 10 years, it was announced on 4 October.
