摘要： A SQUID bias current adjustment device supplies a sinusoidal current at 40 kHz, for example, to a coil to generate magnetic field at a SQUID. The amplitude of the field corresponds to a half period of a field-voltage characteristic. Voltage generated from the SQUID at this time is filtered by using a filter to pick out components of 40 kHz and 80 kHz. The picked out signal components are rectified and converted to direct current, and the bias current is adjusted such that the maximum value is obtained. In this way, a SQUID bias current adjustment device can be provided capable of automatically adjusting bias current properly in a short period of time.

摘要： A modulation current at a predetermined frequency f is applied from an AC source to a flux locked loop for maintaining magnetic flux supplied to a SQUID at a constant value. An output voltage is picked out from the SQUID in this state to which a predetermined bias current is being applied from a current and field bias application circuit, and the picked out voltage passed through a filter and a rectifier is monitored by a voltage monitor. The filter picks out a frequency component of 80 kHz which is twice as high as the frequency component f, 40 kHz, applied from the AC source, and maximizes it. In this way, a method and a device for easily adjusting magnetic field bias in a modulation drive circuit for a SQUID can be provided.

摘要： The present invention provides an improved and simplified voltage step-up circuit (2) for a SQUID magnetometric sensor (1), which provides step-up of a voltage signal generated by a SQUID element (11). The SQUID element is exited by a modulated signal using the FLL method. In an example, a step-up means (22) comprises only one step-up transformer (22T) working at room temperature and an electronic amplifier (22A). The voltage signal is first stepped up by the transformer. A signal processing means (23) processes the stepped up signal with the modulation signal to output a magnetic field measurement signal (V.phi.). In another example, a bias current source (21) is also connected to terminals between SQUID element (11) and the transformer (22). A series resistor is connected between the transformer and one of the terminals. This allows a reduction in the number of terminals between the SQUID sensor (1) and the circuit (2).
