A 7T conduction-cooled MRI whole-body magnet design
using Nb3Sn superconductor is found for a current
density of 179.95 A/mm2, a maximum peak field on a
bundle of 11.59T, and operating at 8K. The high current
density on wire allowed by the larger peak field helps
to reduce the superconductor volume in comparison with
high field NbTi magnet designs. Although the present
manufacturing cost of Nb3Sn is higher than NbTi, the
wire volume reduction and the 99% decrease in liquid
helium usage may make Nb3Sn conduction cooled magnets a
viable alternative for ultra-high field magnet systems.
