Abstract
A superconducting magnet configuration () for generating a homogeneous magnetic field Bin an examination volume (), has an interior radial superconducting main field coil () which is disposed rotationally symmetrically about an axis (z-axis) and an oppositely driven coaxial radially exterior superconducting shielding coil () is characterized in that the magnet configuration () consists of the main field coil (), the shielding coil (), a ferromagnetic field formation device () and a ferromagnetic shielding body (AK), wherein the ferromagnetic field formation device () is located at the radially inside of the main field coil () and the ferromagnetic shielding device (AK) surrounds the main field coil () and the shielding coil () in a radial and axial direction, the main field coil () consisting of an unstructured solenoid coil or of several radially nested unstructured solenoid coils () which are driven in the same direction, the axial extent Lof the shielding coil () being smaller than the axial extent Lof the main field coil (), wherein the axial magnetic field profile () generated by the main field coil () and the shielding coil () during operation has a minimum of the field strength along the axis (z-axis) in the center () and a maximum of the field strength on each side of the center (), and wherein the axial magnetic field profile () generated by the ferromagnetic field formation device () and the ferromagnetic shielding body (AK) during operation has a maximum of the field strength along the axis (z-axis) in the center () and a minimum of the field strength on each side of the center (). The magnet configuration in accordance with the invention has a very simple structure.
