900 MHz 105 mm NMR Magnet

900 MHz Ultra-Wide Bore Magnet. 900 MHz Ultra-Wide Bore Magnet.

At 21.1 tesla, this is the strongest MRI scanner in the world for small animals. It is located in the MagLab's Tallahassee headquarters.

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.
