Abstract
A magnet arrangement comprising a superconducting magnet coil system (M) which has an ohmic resistance (R) of zero or more during operation, and a flux pump (P) which comprises at least one superconducting switch and at least two superconducting secondary coils (M,M), is characterized in that at least one superconducting current path is provided, wherein the superconducting magnet coil system (M) or parts thereof is/are connected in series with at least two secondary coils (M, M), and wherein at least one secondary coil (M) can be superconductingly bridged through closing of a superconducting switch (S), and at least two primary coils (C, C) are provided which can each be fed independently of each other with a current (I, I) and which are each inductively coupled with at least one of the secondary coils (M, M). The flux pump is suitable for the stabilization of the magnetic field of the magnet coil system (M) during long-term operation.
