摘要： In the apparatus for cooling a superconductor in accordance with the present invention, a male thread portion of an inner container engages a female thread portion of an outer container so as to connect the inner and outer containers to each other. Also, the bottom wall of the inner container is provided with a thermal conductor penetrating therethrough. Further, a sapphire sheet is joined to peripheral portions of an opening of the bottom wall of the outer container facing the thermal conductor, so as to block the opening. As the distance between the bottom wall of the outer container and the bottom wall of the inner container is freely adjusted by changing the engaging position between the thread portions, the gap between a high transition temperature (high Tc) superconducting magnetic sensor and the sapphire sheet is adjusted.

摘要： This magnetic sensor comprises a flux transformer 2 having a superconducting thin film 2f formed on a sapphire substrate 2s, and a SQUID 1 disposed on the flux transformer 2 opposite thereto. In this magnetic sensor, since the sapphire substrate 2s, which can be obtained in a large size, is used for the flux transformer 2, even when the SQUID 1 is made smaller, the magnetic flux introduced from the flux transformer 2 into the SQUID 1 can be enhanced so as to increase the effective magnetic flux capturing area, whereby the detecting performance is improved, while the manufacturing cost can be reduced due to the smaller size of the SQUID 1.

摘要： A circuit device for driving a SQUID magnetometric sensor. This device includes an FLL magnetometer circuit for driving the SQUID with an AC signal as a magnetometric sensor, an evaluator circuit for evaluating the SQUID characteristics, and a selector circuit for selecting a sensor function or an evaluator function. When the selection circuit selects one of the sensor and evaluator functions, only one of magnetometer and evaluator circuits is activated. Therefore, the circuit device can act alternatively as either a sensor or an evaluator.
