Abstract

Eine Magnetanordnung mit einem supraleitenden Magnetspulensystem (M), welches im Betriebszustand einen Ohmschen Widerstand (R) größer oder gleich null aufweist, und mit einer Flusspumpe (P), welche mindestens einen supraleitenden Schalter und mindestens zwei supraleitende Sekundärspulen (M1, M2) umfasst, ist dadurch gekennzeichnet, dass mindestens ein supraleitender Strompfad vorhanden ist, in welchem das supraleitende Magnetspulensystem (M) oder Teile davon mit mindestens zwei Sekundärspulen (M1, M2) zusammen in Serie geschaltet ist und in welchem mindestens eine Sekundärspule (M2) durch Schließen eines supraleitenden Schalters (S1) supraleitend überbrückt werden kann, und dass mindestens zwei Primärspulen (C1, C2) vorhanden sind, welche unabhängig voneinander mit je einem Strom (I1, I2) gespeist werden können und welche jeweils mit mindestens einer der Sekundärspulen (M1, M2) induktiv gekoppelt sind. Die Flusspumpe kann gut zur Stabilisierung des Magnetfelds des Magnetspulensystems (M) im Betriebszustand über lange Zeit eingesetzt werden.

A magnet arrangement comprising a superconducting magnet coil system ( M ) which in operation has an ohmic resistance ( R ) greater than or equal to zero, and a flux pump ( P ) comprising at least one superconductive switch and at least two secondary superconducting coils ( M1, M2 ), is characterized in that there is at least one superconducting current path in which the superconducting magnet coil system ( M ) or parts thereof is connected in series with at least two secondary coils ( M1, M2 ) and in which at least one secondary coil ( M2 ) is formed by closing a superconducting one Switch ( S1 ) can be bridged superconducting, and that at least two primary coils ( C1, C2 ) are present, which can be fed independently with one current ( I1, I2 ) and which in each case with at least one of the secondary coils ( M1 , M2 ) are inductively coupled. The flux pump can be used well for stabilizing the magnetic field of the magnetic coil system ( M ) in the operating state for a long time.
