AUTO-DRAFT

We provide a low-temperature niobium-based SQUID magnetometer developed by SIMIT.

 

● Application scope: biomagnetic detection, geophysics, triaxial compensation, etc.

Customized by users: A variety of SQUID magnetometers can be designed to meet different application requirements.

● Packaging design: reliable non-magnetic material packaging, such as glass fiber reinforced plastic, Shi Ying, etc.

● Working conditions: Magnetometer can be directly immersed in liquid helium.

● Signal readout: For self-made readout circuit to realize amplification and feedback, that is, to realize SQUID flux lock loop readout.

 

design:

● Based on reliable Nb/Al-AlOx/Nb

josephson knot process

● Magnetometer size 10 × 10 mm2

● Integrated heating resistor to realize magnetic flux removal

superior performance:

● Magnetic flux noise 5 μФ 0/& radic;Hz

● magnetic field noise 2.9fT/& radic;Hz

● Magnetic field sensitivity 0.58nT/Ф 0
