Abstract
A magnet arrangement comprising an actively shielded superconducting magnet coil system (M) and a plurality of protective elements (R1, . . . , Rl) for protection in case of a quench, wherein the superconducting magnet coil system (M) comprises a radially inner partial coil system (C1) and a radially outer partial coil system (C2) which are electrically connected in series and arranged coaxially with respect to one another and which each produce a magnetic field of opposite direction, wherein the superconducting current path of the magnet coil system (M) is subdivided into several sections (A1, . . . , An) each of which is electrically connected in parallel with at least one of the protective elements (R1, . . . , Rl), and wherein at least one of these sections (A1, . . . , An) comprises windings of the radially inner partial coil system (C1) and also windings of the radially outer partial coil system (C2), is characterized in that at least one additional closed current path (C3) is provided which has a non-vanishing areal winding number and which has a non-zero inductive coupling LAi⇄C3 with at least one section Ai. This permits—in particular through selection of the d…
