The final commissioning of the 11.7 T Iseult magnet is going to start in the mid of 2017 at NEUROSPIN laboratory. Before that, the dedicated cryoplant, electrical equipment, control-process and instrumentation have already been installed and tested in order to validate all the operation parameters and the component capabilities. Cryogenic tests have been performed to confirm heat loads and cryo-mechanical performances of the cryogenic satellite connected to the helium refrigerator, and the 1.8 K stage was commissioned as well. Power supplies, electrical circuits, Magnet Safety System have been operated up to the nominal current, while electrical insulation has been verified. Finally, the Magnet Control System and its ancillaries have been qualified to ensure a continuous and highly reliable operation of the system.
