Our ultra-wide bore 900 MHz NMR magnet (105 mm) was designed and built by the NHMFL's own 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.
Since then, research proposals for the time on this instrument are accepted from interested scientists worldwide in all three areas of NMR:
solid state, solution and imaging.
An article on the magnet construction is available as a
screen optimized (321 Kb) or
print optimized (4.4 Mb) PDF files.
We encourage potential users to apply for time on this 900 MHz instrument.
Research proposals for the instrument time should be submitted to Dr. R. Fu in accordance with the steps outlined here.
Experimental time is usually alloted prior to the start of each month.
