A flat multi-layer arrangement ( 1; 1 a –1 f ) of superconducting wires ( 4,5 ) with normally conducting substrate ( 17 ) and at least one fiber ( 16 ) which is electrically conductingly connected to the substrate ( 17 ) and is superconducting under predetermined operating conditions is characterized in that the superconducting wires ( 4, 5 ) in a respective layer ( 2, 3; 22, 23 ) are substantially disposed such that they do not cross. A resistive electric contact is provided between the superconducting wires ( 4, 5 ) of different layers ( 2,3; 22, 23 ) and the superconducting wires ( 4, 5 ) of at least two neighboring layers ( 2, 3; 22, 23 ) do cross, wherein no closed superconducting loops are present in the arrangement ( 1; 1 a –1 f ). This arrangement permits shielding of the working volume of a magnet coil arrangement against low-frequency stray fields in an efficient and reliable manner. |
