GRADIENT COIL SYSTEM FOR NMR MACHINES

摘要

In a system of compensated gradient coils, gradient coils mounted on two mandrels (3, 4) coaxial with an examining region (2) of an NMR machine have useful conductors distributed in such a way that when a nominal current flows through them they induce a zero magnetic vector potential in preferred regions of the space in which the production of undesirable eddy currents is to be prevented.
