In one embodiment, the nondestructive testing unit includes a plurality of detection coils, a SQUID having a pair of connectors for connection to the detection coils, a probe for supporting the detection coils and the SQUID in a coolant, a cryostat for supporting the probe and for keeping the coolant constant, a controller for processing a signal transmitted from the SQUID, and a display device for displaying the result of the processing. At least two detection coils are disposed in the same plane, are directly connected to the SQUID and are integrated on a semiconductor substrate.

摘要： A nondestructive inspection apparatus having a SQUID is made with compact configuration and is capable of detecting a metallic or non-metallic metal for defects, corrosion, and the like, by forming the SQUID and a magnetic field applying coil on the same substrate. The SQUID comprises two Josephson junctions, a washer coil connected to the Josephson junctions to form a superconducting loop, shunt resistors, a damping resistor, and a feedback modulation coil, all of which are formed from a superconducting thin film on a supporting substrate. A magnetic field applying coil is formed on the same supporting substrate with a superconducting thin film or a normal conducting metal thin film. The magnetic field applying coil, which generally has plural turns around the SQUID, applies a dc or ac magnetic field to a sample. The change in magnetic field caused by a defect in the sample is detected by the washer coil, and the position and size of the defect may thus be determined. Since the magnetic field applying coil is integrated on the same substrate as that on which the SQUID is formed, the apparatus may be made compact.

摘要： An apparatus for detecting a fine magnetic field comprises a DC SQUID which detects and converts a magnetic field to an electrical signal. A flux locked looped circuit drives the DC SQUID. The flux locked loop circuit includes an amplifier for amplifying the electrical signal. A phase detector modulates the amplified electrical signal and an integration circuit outputs a voltage signal corresponding to the detected magnetic field. An oscillator coupled to the phase detector supplies a demodulation frequency signal. A modulator including a first voltage-to-current converter and a second voltage-to-current converter is coupled with the integration circuit and the oscillator for supplying a modulation signal to the DC SQUID. The modulator further includes an external input terminal and a feedback modulation change-over circuit for changing an internal feedback signal to an external test signal inputted to the external input terminal. A bias source having a third voltage-to-current converter is coupled to the DC SQUID and supplies a bias signal. The bias source also includes an external input terminal and a change-over circuit for changing an internal bias signal to an external test signal inputted to the second external input terminal. An external output terminal is connected to the amplifier for supplying a monitoring test output signal from the DC SQUID. The apparatus for detecting a fine magnetic field thus provides a self-testing function for the DC SQUID.
