Suppression of current source noise with an atomic magnetometer

Review of Scientific Instruments, 2020
This paper introduces a method for using an atomic magnetometer to suppress current source noise. In this method, the current noise is (i) suppressed with a lamp-pumped cesium atomic magnetometer and (ii) measured with a higher-sensitivity laser-pumped cesium atomic magnetometer.

Chip scale atomic magnetometer based on SERF

2009 4th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2009
We are developing a new detection scheme for magnetometers based on atomic vapor confined in millimeter-scale micromachined enclosures and atomic Zeeman transitions. By adding three micro-reflective mirrors and modifying the light path arrangement, the new detection scheme effectively hurdles the main obstacle which prevents SERF from being applied in ...

Highly sensitive multi-channel atomic magnetometer

2018 IEEE Sensors Applications Symposium (SAS), 2018
We describe a high-sensitivity 16-channel magnetic sensor based on a spin-exchange relaxation-free (SERF) atomic magnetometer, the most sensitive cryogen-free magnetic field sensor. It has been developed in order to accelerate magnetic measurements in various fields, such as neuroscience and biomedical research, and improve the current technologies ...

Dynamical MCG mapping with an atomic vapor magnetometer.

Neurology & clinical neurophysiology : NCN, 2004
We have developed a magnetometer based on magnetic resonance in cesium vapor optically pumped by resonant laser radiation, which has the sensitivity and bandwidth to record human magnetocardiograms. The device is operated as a first-order gradiometer in a weakly shielded environment and allows us to record 2-dimensional field maps by shifting the ...
