900 MHz 105 mm NMR & MRI/S system

900Mhz 105Mm Ultra Wide Bore Magnet

At 21.1 tesla, this is the strongest MRI scanner in the world for small animals, and is also used for solid state NMR.

Magnet Schedule

See the schedule of upcoming users on this instrument.

This ultra-wide bore 900 MHz NMR magnet (105 mm) was designed and built by the MagLab’s Magnet Science and Technology department. The magnet reached its full field of 21.1 tesla on July 21, 2004, without incurring any training quenches. Regular user operations started on August 1, 2005.
