ABSTRACT:
A co-axial magnet configuration for the production of a magnetic field and investigational volume which is suitable for measurement of magnetic resonance has at least one superconducting solenoid coil or solenoid coils which are radially nested within each other, wherein the windings of the solenoid coil(s) in a radial region about the axis of the magnetic configuration are disposed between r1and r2, wherein r1<r2is characterized in that the windings are surrounded by at least one rotationally symmetric magnet body made from ferromagnetic material which extends over a radial region between r3and r4wherein r3<r4wherein r2<r3<1.3 r2and r4>1.3 r3, wherein the rotationally symmetric magnet body or bodies are structured, dimensioned and positioned in such a fashion that the magnetic field is homogenized in the investigational volume and the magnetic fringe field outside the magnet configuration is essentially suppressed to permit the production of strong magnetic fields of high homogeneity without requiring notches in the coil configuration.
