Mapping plasma structures in the high-latitude ionosphere using beacon satellite, incoherent scatter radar and ground-based magnetometer observations
Beacon satellites ionospheric plasma
2015/9/25
In the autumn of the year 2000, four radio receivers capable of tracking various beacon satellites were set up along the southwestern coast of Greenland. They are used to reconstruct images of the ion...
Optical Magnetometer Array for Fetal Magnetocardiography
Optical Magnetometer Array Fetal Magnetocardiography
2012/2/28
We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are configured with a small...
Detection of a single cobalt microparticle with a microfabricated atomic magnetometer
single cobalt microparticle microfabricated atomic magnetometer Instrumentation and Detectors
2011/8/3
Abstract: We present magnetic detection of a single, 2 {\mu}m diameter cobalt microparticle using an atomic magnetometer based on a microfabricated vapor cell. These results represent an improvement b...

Instrumentation and measurement, Atomic and molecular physics, Medical physics, Biological physics
2011/9/6
We present a portable four-channel atomic magnetometer array operating in the spin exchange relaxation-free regime. The magnetometer array has several design
features intended to maximize its suitabi...
Limit on Lorentz and CPT violation of the bound Neutron Using a Free Precession 3He/129Xe co-magnetometer
Lorentz CPT violation of the bound Neutron Free Precession 3He/129Xe co-magnetometer
2010/12/20
We report on the search for Lorentz violating sidereal variations of the frequency difference of colocated spin-species while the Earth and hence the laboratory reference frame rotates with respect to...
