Electromagnetic Induction Imaging: Signal Detection Based on Tuned-Dressed Optical Magnetometry
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +3
A recently introduced tuning-dressed scheme makes a Bell and Bloom magnetometer suited to detect weak variations of a radio-frequency (RF) magnetic field. We envisage the applicati…
Fast, cheap, and scalable magnetic tracker with an array of magnetoresistors
Valerio Biancalana, Roberto Cecchi, Piero Chessa +3
We present the hardware of a cheap multi-sensor magnetometric setup where a relatively large set of magnetic field components is measured in several positions by calibrated magneto…
Ferromagnetic contamination of Ultra-Low-Field-NMR sample containers. Quantification of the problem and possible solutions
Giuseppe Bevilacqua, Valerio Biancalana, Marco Consumi +4
The presence of a weak remanence in Ultra-Low-Field (ULF) NMR sample containers is investigated on the basis of proton precession. The high-sensitivity magnetometer used for the NM…
Fast switching coil system for sample premagnetization in an unshielded ultra-low-field Nuclear Magnetic Resonance experiment
Valerio Biancalana, Roberto Cecchi, Leonardo Stiaccini +1
We present a system developed to premagnetize liquid samples in an ultra-low-field Nuclear Magnetic Resonance (NMR) experiment. Liquid samples of a few milliliter are exposed to a…
Spurious Ferromagnetic Remanence Detected by Hybrid Magnetometer
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +2
Nuclear magnetic resonance detection in ultra low field regime enables the measurement of different components of a spurious remanence in the polymeric material constituting the sa…
Self-adaptive loop for external disturbance reduction in differential measurement set-up
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
We present a method developed to actively compensate common-mode magnetic disturbances on a multi-sensor device devoted to differential measurements. The system uses a field-progra…
