Abstract
Apparatus comprising a gradiometer array having a plurality of gradiometers, with which at least one SQUID array having a multiplicity of DC-SQUIDs is associated therewith forms, with the respective coupling coils, modulation coils and superconducting shielding rings serving for the magnetic decoupling, a thin-film structure. Furthermore, metallic coupling by ground planes is provided for at least part of the common leads. By the metallic coupling and magnetic decoupling of the parallel measuring channels, a simple embodiment with few contacts is obtained which makes possible parallel signal processing without crosstalk.
