Superconducting wide-bore magnets

The size of the superconducting magnet is as small as a wide-bore NMR probe. 

A pulsed NMR spectrometer, with a variable frequency and variable temperature facility is best suited for the study of these disordered systems.26 27 For dipolar glasses and relaxor systems, a spin echo Fourier transformation NMR spectra of the system have been measured in a wide bore superconducting magnet ( typically at 9.2 T). 

The experiments reported in this article have all been performed on a FT NMR spectrometer built in our laboratory at Lund. The instrument employs a wide-bore 6.0 Tesla superconducting magnet, custom made by Oxford Instruments, Oxford, England. In order to achieve the highest possible sensitivity the probes are of the solenoid type(lO) and sample tubes - usually containing about 3 ml of sample - are...
