Problems solved by technology

However, the axial gradiometers currently used rely on foreign imports and have not yet achieved complete autonomy, which seriously restricts the further development of the magnetic-cardiometer system.
Moreover, this axial gradiometer realizes the connection between the SQUID chip and the gradient coil by means of nut pressing. In some cases, there will be a weak connection, and the SQUID chip will be damaged due to improper operation.
In addition, during use, because the SQUID chip and the gradient coil are not integrated, it will also cause difficulties in assembly

Description

technical field [0001] The invention relates to the technical field of axial gradiometers, in particular to a manufacturing device and method of an axial gradiometer based on superconducting connections. Background technique [0002] Due to its high sensitivity, non-contact and completely non-invasive features, magnetocardiograph is expected to become a new generation of medical research and clinical diagnostic equipment. The performance of a magnetocardiograph depends on the quality of the detected magnetic signals. The typical value of the cardiomagnetic signal is tens to hundreds of pT (10 -12 T), while the environmental field noise is very strong, such as the typical strength of the earth's magnetic field is 30 ~ 50μT, the urban environmental field noise can reach hundreds of nT. In order to extract extremely weak cardiomagnetic signals from such a strong background magnetic field, not only high-sensitivity magnetic sensors, such as Superconducting Quantum Interference...
