Production Results of 11.75 Tesla Iseult/INUMAC MRI Conductor at Luvata

Large quantities of NbTi-based superconductors have been produced for the 11.75 Tesla whole body magnetic resonance imaging project called the Iseult/INUMAC managed by CEA Saclay. The magnet is designed to operate at 1.8 K. Production consisted of nearly 65 t (170 km) of a large 9.2 mm × 4.9 mm Ruth...

Zusammenfassung:Large quantities of NbTi-based superconductors have been produced for the 11.75 Tesla whole body magnetic resonance imaging project called the Iseult/INUMAC managed by CEA Saclay. The magnet is designed to operate at 1.8 K. Production consisted of nearly 65 t (170 km) of a large 9.2 mm × 4.9 mm Rutherford cable-in-channel for the main coil and 22 t (58 km) of a 9.1 mm × 4.2 mm wire-in-channel for the shield. These have been successfully manufactured, inspected, and delivered. The key technical requirements were dimensional precision, superconducting properties, RRR, and tensile strength. An extensive quality assurance program was instituted to guarantee the final conductor performance. Measured degradation in superconducting characteristics due to cabling and solder integration were negligible (
