摘要： The invention relates to a SQUID system having an increased flux voltage transfer function. The object of disclosing a circuit configuration providing an increased flux voltage transfer function of a SQUID, wherein the measurement sensitivity of the system is noticeably increased and the required readout electronics are simplified, is achieved in that at least one SQIF is provided as an amplifier circuit and is connected downstream of the first SQUID, wherein a coupling coil electrically connected to the first SQUID is directly associated with all loops of the SQIF.

摘要： The invention relates to a SQUID arrangement for measuring a change in a magnetic field, the change in the magnetic field being caused by a specimen that is arranged in a magnetization field and the SQUID arrangement including a direct current SQUID. In order to provide a simple design in which the losses in the magnetic flux are also simultaneously minimized, it is provided that the SQUID itself is embodied for generating the magnetization field.

摘要： A receiver system (18) for an electromagnetic prospecting system is disclosed. The electromagnetic prospecting system comprises a transmitter for transmitting a primary electromagnetic field so as to generate a secondary electromagnetic field from a terrain that is being prospected, the secondary electromagnetic field having a transient, decaying time domain profile. The receiver system (18) comprises first and second sensors (20, 22) for detecting the secondary electromagnetic field, wherein the second sensor (22) is less sensitive than the first sensor (20) so as to detect the secondary electromagnetic field over a first time period, with the first sensor (20) being used to detect the secondary electromagnetic field after the first time period. Typically, each sensor (20, 22) comprises three orthogonal SQUID magnetometers, with the second sensor (22) being approximately 10 times less sensitive than the first sensor (20).
