dc SQUID readout electronics





SQUID readout circuit
with bias reversal, and control box with built-in rechargable battery.

Our dc SQUID readout circuits SQE-DC-100k and SQE-DC-400k are also available with bias-reversal modulation.  Bias reversal will suppress low-frequency excess noise produced by critical current fluctuations, and is especially helpful when reading out high-temperature superconductor SQUIDs.  1/f noise produced by critical current fluctuations can also be a problem in LTS SQUIDs when magnetic fields at very low frequencies (mHz) have to be measured.
