On July 6, 2017, in the presence of Daniel Verwaerde, Chief Executive Officer of the CEA, André Syrota, Advisor to the Chief Executive Officer, Claire Corot, Director of Research and Innovation at Guerbet, Serge Ripart, Director of Imaging at Siemens Healthcare France, and Gilles Bloch, President of the Université Paris-Saclay, the 132-tonne giant magnet of the Iseult project officially integrated the NeuroSpin research infrastructure at the CEA Centre in Paris-Saclay (Essonne). This very high-tech object, which is the main component of the world's most powerful MRI (Magnetic Resonance Imaging) scanner for imaging the human brain, will produce a magnetic field of 11.75 teslas, nearly 230,000 times the Earth's magnetic field. To reach this level of magnetic field, CEA research engineers had to design an extraordinary superconducting magnet!
