Magnet for NMR Systems

JEOL Resonance has developed a Nuclear Magnetic Resonance (NMR) super conducting magnet that operates on a minimum amount of liquid helium. It is capable of acquiring high resolution NMR data when liquid helium is scarce. A super conducting magnet is typically cooled with liquid helium to keep its internal coil in the super conducting state and to maintain magnetic field intensity.

The Resonance Zero Boil Off magnet is designed to substantially reduce consumption of liquid helium by reliquifying the helium gas generated by evaporation of the helium in the magnet. In the event of a power outage the helium reservoir will maintain the magnetic field for four days. The cooling system design allows for biannual maintenance without affecting the high magnetic field of the super conducting magnet and minimizes vibration and noise that can interfere with NMR signals.
