Impact of third order shim coils on gradient-magnet interactions and gradient waveform fidelity Open
Motivation: Third order shim coils can impact gradient-magnet interactions with consequences on image quality and magnet safety. Goal(s): To demonstrate the influence of third order shim coils on the SC72 gradient coil using field and vibr…

Measurements of the gradient-induced power deposition in the He-bath of the Iseult 11.7T magnet and comparison with theory Open
Motivation: Experimental characterization and understanding of the power deposition in the He bath of an ultra-high field magnet is important for magnet safety. Goal(s): We report a quasi-analytical model for the Z gradient axis power depo…

Power deposition in the He bath induced by the Z gradient coil in the 11.7 T Iseult magnet: theory versus measurements Open
Gradient-magnet interactions increase with higher field magnets and stronger gradient coils. Perhaps the most sensitive aspect is magnet quench, which can be induced by a loss of superconductivity of the main coil caused by a rise of the t…

Vibration measurements of the SC72 gradient versus field strength in the Iseult magnet Open
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 …

Bright muon beams and muon colliders Open
Muon collider (MC) technology must overcome several significant challenges to reach the maturity of electron-positron colliders. An increased level of R&D effort is justified at the current time, because the muon collider promises an alter…
