Abstract
The gradiometers are arranged with their associated SQUIDs in a double-wall Dewar vessel which is equipped with a narrow neck. A gradiometer array is provided with a multiplicity of individually mountable gradiometers, the detector coils of which are arranged side-by-side. The radiometers are connected via a superconducting plug connection to a SQUID array of DC-SQUIDs which is designed with a measuring head and a multiple connector as a plug-in module. The multiple connector can be inserted with the SQUID array through the neck of the Dewar vessel and can be plugged into a mating plug-in device which is associated with the gradiometer array and is fastened by a mounting device to the bottom of the Dewar vessel. In this embodiment of the apparatus, for instance, a plane gradiometer array for magnetocardiography can be exchanged for a curved gradiometer array for magnetoencephalography.
