The whole-body Iseult 11.7T CEA magnet has delivered its first images after nearly 20 years of research and development. Before reaching this long-waited step, a gradient coil–magnet interaction test campaign was run for several months at 3T, 7T, 10.2T and 11.7T on the same identical system. It included acoustics, vibrations, magnet safety system voltage and power deposition in the He bath measurements. Some vibration results versus field strength are presented here. Vibration amplitudes are shown to increase less than with B0 field strength.
