High Tc SQUID Detector for Magnetic Metallic Particles in Products
High-Tc superconducting quantum interference device (SQUID) is an ultra-sensitive magnetic sensor. After the discovery of the high-Tc superconducting materials, the performance of the high-Tc SQUID has been improved and stabilized. One strong candidate for application is a detection system of magnetic foreign matters in industrial products. There is a possibility that ultra-small metallic forei...
متن کاملTopical Review High-Tc SQUID biomagnetometers
In this paper, we review the preparation technology, integration in measurement systems and tests of high-Tc superconducting quantum interference devices (SQUIDs) intended for biomagnetic applications. A focus is on developments specific to Forschungszentrum Jülich GmbH, Chalmers University of Technology, MedTech West, and the University of Gothenburg, while placing these results in the perspec...
متن کاملApplications using high-Tc superconducting terahertz emitters
Using recently-developed THz emitters constructed from single crystals of the high-Tc superconductor Bi2Sr2CaCu2O8+δ, we performed three prototype tests of the devices to demonstrate their unique characteristic properties for various practical applications. The first is a compact and simple transmission type of THz imaging system using a Stirling cryocooler. The second is a high-resolution Mich...
متن کاملMetallic Contaminant detection Systems for Foods and Beverages by High Tc SQUID Magnetic Sensor
A computer controlled contaminant detection systems based on high-Tc Superconducting Quantum Interference Device (SQUID) for food and drink have been designed and constructed. The systems we have developed are the High-Tc SQUID based systems, which are covered with waterproof stainless steel plates and acceptable to HACCP (Hazard Analysis and Critical Control Point) program. One system is for f...
متن کاملImproving high-Tc dc-SQUID performance by junction asymmetry
We study noise and noise energy of a high-Tc dc SQUID fabricated on a high-ǫR substrate whose conduction properties are given by transmission line physics. We show that transmission line resonances greatly enhance the noise. Remarkably, resistance asymmetry enhances these resonances even more. However, as the transfer function (dc dφ ) scales the same way, the noise energy is reduced by asymmet...
