Abstract
A magnet arrangement comprising a superconducting magnet coil system (M) for producing a magnetic field in the direction of a z axis in a working volume (AV) disposed on the z axis about z=0, wherein the superconducting magnet coil system (M) comprises a radially inner partial coil system (C1) and a radially outer partial coil system (C2) which is coaxial thereto, and with a field forming device (P) of magnetic material disposed in a preferably cylindrically symmetrical fashion about the z axis, located radially between the radially inner and the radially outer partial coil system (C1, C2), and being coaxial with respect to the two partial coil systems (C1, C2), wherein the radially inner partial coil system (C1) produces a homogeneous field in the working volume (AV) and the radially outer partial coil system (C2) produces an inhomogeneous field in the working volume (AV) is characterized in that the radially outer partial coil system (C2) produces, together with the magnetic field forming device (P), a homogeneous field in the working volume (AV), wherein the magnetic material of the field forming device (P) is largely magnetically saturated with its magnetization pointing substa…
