Field validation of GNSS-independent positioning enhancement using a wearable ultra-stable quantum magnetometer
Stirling Scholes, Dominic Hunter, Courtney Dyer +8
Increasing the resilience of positioning systems that currently rely on Global Navigation Satellite System (GNSS) signals can be achieved by incorporating stable and sensitive meas…
Intrinsic atomic calibration of oscillating magnetic fields in ULF and VLF bands
Zak Johnston, Paul F. Griffin, Erling Riis +3
We present a method for absolute calibration of received radio-frequency in the ultra low frequency (ULF), and very low frequency (VLF) range. This is achieved with the use of a ra…
High-Resolution Atomic Magnetometer-Based Imaging of Integrated Circuits and Batteries
Dominic Hunter, Marcin S. Mrozowski, Stuart J. Ingleby +7
Optically pumped magnetometers (OPMs) have emerged as a powerful technique for high-resolution magnetic field imaging. However, achieving sub-millimeter spatial resolution at sub-p…
A triaxial vectorization technique for a single-beam zero-field atomic magnetometer to suppress cross-axis projection error
Rach Dawson, Marcin S. Mrozowski, Dominic Hunter +4
Zero-field optically pumped magnetometers (OPMs) have emerged as an important technology for biomagnetism due to their ulta-sensitive performance, contained within a non-cryogenic…
Distributed network of optically pumped magnetometers for space weather monitoring
M. S. Mrozowski, A. S. Bell, P. F. Griffin +6
Spatial variation in the intensity of magnetospheric and ionospheric fluctuation during solar storms creates ground-induced currents, of importance in both infrastructure engineeri…
An additive-manufactured microwave cavity for a compact cold-atom clock
Etienne Batori, Alan Bregazzi, Ben Lewis +4
We present an additive-manufactured microwave cavity for a Ramsey-type, double resonance, compact cold-atom clock. Atoms can be laser cooled inside the cavity using a grating magne…
