A stone’s throw away, on the CEA-Cadarache side, their microscopic counterpart: no more than 50 nanometres in size (50 billionth of a metre!). Magnets by the hundreds of millions packed into one single drop of water.
The bulkiest among the ITER magnets, much too big to be transported along the specially adapted ITER Itinerary, will be assembled in a 257-metre-long building on site. CEA’s nanomagnets are being produced naturally. Bacteria—not industry—are doing the job.
