A magnetometer (20) comprises a magnetic field pickup coil (22) and a magnetic field detector (26) that receives electrical signals from the pickup coil (22) and produces an electrical detector output (28) responsive thereto. The pickup coil (22) and detector (26), which are preferably made of high temperature superconductors, are enclosed in an insulated enclosure (32) having no vacuum insulation structure. Preferably, the enclosure is made of a foamed polymer material such as styrofoam. A coolant is provided to the interior of the enclosure, to cool the pickup coil and detector to a temperature below their superconducting transition temperature. A number of such modular magnetometers may be connected together to form an array. <IMAGE> |
