Abstract
The nuclear magnetic resonance machine comprises a device () for creating an intense main magnetic field Bin a usable interior space () in the form of a tunnel with axis Z, a radio-frequency excitation device that also processes radio-frequency signals emitted in response by a body () placed in the usable interior space (), and a set () of solenoidal gradient coils for superimposing on the intense magnetic field Bcomponents of a additional magnetic field, the gradient coils (-) being incorporated into tubes disposed in an annular cylindrical space (). Between an exterior cryogenic enclosure () and the annular cylindrical space () a cylindrical screen () is disposed along the axis Z comprising a conductive material of low resistance and low magnetoresistance such that negligible induced currents are generated in the exterior cryogenic enclosure () while the eddy currents induced in the cylindrical screen () contribute to reinforcing the gradients produced by the solenoidal gradient coils (-).
