Abstract
A SQUID measurement apparatus for detecting weak magnetic field signals that change over time such as from a biomagnetic field source includes at least one measurement channel, a SQUID, and a superconductive flux transformer disposed in front of the SQUID that includes at least one detection loop for receiving the weak magnetic field signals. The apparatus also includes at least one connection conductor coupled to the detection loop and electromagnetically shielding for at least the at least one connection conductor of the flux transformer. The shielding includes at least one superconductive shielding element that extends in a direction substantially parallel to the at least one connection conductor and substantially equidistant from the at least one detection loop. The shielding element has a discontinuity at a separation point in a region of the detection loop.
