# Micrograph of a SQUID amplifier

Micrograph of a SQUID amplifier, made at NIST in 2012, that is part of a circuit used to read signals from arrays of superconducting sensors. Small currents generated by the sensors are carried and amplified in the coils, which create magnetic fields detected by the SQUID (two small squares in the center of the image).
