System of production coils of additional fields to get constant gradient polarization field in a magnet including polarization polar for nuclear magnetic resonance
Description
The system includes two sheets of orthogonal windings for gradient creation, one sheet on each polar piece; two winding systems for gradient creation on the third coordinate, two winding systems with circular symmetry, placed on the inner faces opposite to polar pieces and went through by opposite currents from a polar piece to another

Il comprend: pour la creation des gradients Gx = δBz/δx et Gy = δBz/δy, deux nappes d'enroulements orthogonales, une sur chaque piece polaire; pour la creation du gradient Gz = δBz/δz, deux systemes d'enroulements de symetrie circulaire d'axe Oz, situes sur les faces internes en regard des pieces polaires et parcourus par des courants de sens opposes d'une piece polaire a l'autreAdditional details
