- Abstract
- Magnetometers based on Superconducting Quantum Interference Device (SQUID) are
widely employed in high sensitivity magnetometry. In particular, new multichannel sys-
tems for biomagnetic applications require many sensors which are very close to each other
giving the crosstalk disturbance between the neighboring channel. Here, we present ex-
perimental results about a fully integrated dc-SQUID magnetometer, based on niobium
technology, having a suitable design which allows to reduce crosstalk due to both the
feedback coil and wires.
The crosstalk level measurements relative to a particular arrangement of sensors
are reported. In such configuration, four magnetometers are placed over a square board
30 mm in side with a distance between their sensor centers of 14 mm. The measurements
have been performed in a 4 He cryostat at T = 4.2 K in a flux-locked loop configuration
using a readout electronics with a direct coupled scheme. The experimental data have
shown a substantial reduction of crosstalk among neighboring sensors with respect to a
traditional feedback coil. Furthermore, the field noise measurements have ensured that
the new pickup and feedback coils design does not introduce any noise level degradation. (literal)
