Document Type and Number:
WIPO Patent Application WO/2021/065689
Kind Code:
A1
Abstract:
A magnetic-field measuring apparatus includes a SQUID; and flux-locked loop circuitry including first circuitry that includes an amplifier connected to an output of the SQUID, and second circuitry connected to the first circuitry. The first circuitry is along an inner surface or an outer surface of a shielding material that separates an inside of a magnetically shielded room from an outside of the magnetically shielded room, the magnetically shielded room including the SQUID. The second circuitry is in the outside of the magnetically shielded room.
