A magnet configuration comprising a superconducting magnet coil system (M)
and a current path (P) which comprises parts of the magnet coil system
(M), wherein at least two electric connecting points (A1, A2, A3, A4) are
disposed on the current path (P), which define a section (P.sub.A1-A2,
P.sub.A2-A3, P.sub.A3-A4) within the current path (P), wherein the
section (P.sub.A1-A2, P.sub.A2-A3, P.sub.A3-A4) does not comprise all
parts of the magnet coil system (M) contained in the current path (P),
and comprising a resistive element (W.sub.A1-A2, W.sub.A2-A3,
W.sub.A3-A4) having an electric resistance value .gtoreq.0, and at least
two contacts (K1, K2, K3, K4), wherein the contacts (K1, K2, K3, K4) are
disposed between the resistive element (W.sub.A1-A2, W.sub.A2-A3,
W.sub.A3-A4) and one connecting point (A1, A2, A3, A4), is characterized
in that in the superconducting state of the magnet coil system (M), an
electric contact (K1, K2, K3, K4) between an electric connecting point
(A1, A2, A3, A4) and a resistive element (W.sub.A1-A2, W.sub.A2-A3,
W.sub.A3-A4) can be closed and opened. The inventive magnet configuration
provides quench protection and also effective disturbance compensation.
