Abstract
A compact, open geometry U-shaped magnet formed by parallel iron slabs and a flux return is activated by a coil which surrounds the flux return. The inner surfaces of the iron slabs and an outer surface of the coil are substantially contiguous. The field homogeneity within the compact, open geometry U-shaped magnet is improved by controlling the reluctance of a secondary flux flow circuit extending away from the pair of parallel iron slabs. The geometry of the compact, open geometry U-shaped magnet also provides for utilization of an automatic active shimming system.
