Alignment-Based Optically Pumped Magnetometer Using a Buffer-Gas Cell (2023)
Journal Article
Rushton, L. M., Elson, L., Meraki, A., & Jensen, K. (2023). Alignment-Based Optically Pumped Magnetometer Using a Buffer-Gas Cell. Physical Review Applied, 19(6), Article 064047. https://doi.org/10.1103/PhysRevApplied.19.064047

Alignment-based optically pumped magnetometers (OPMs) are capable of measuring oscillating magnetic fields with high sensitivity in the fT/Hz range. Until now, alignment-based magnetometers have only used paraffin-coated vapour cells to extend the sp... Read More about Alignment-Based Optically Pumped Magnetometer Using a Buffer-Gas Cell.

Unshielded portable optically pumped magnetometer for the remote detection of conductive objects using eddy current measurements (2022)
Journal Article
Rushton, L. M., Pyragius, T., Meraki, A., Elson, L., & Jensen, K. (2022). Unshielded portable optically pumped magnetometer for the remote detection of conductive objects using eddy current measurements. Review of Scientific Instruments, 93(12), Article 125103. https://doi.org/10.1063/5.0102402

Electrically conductive objects can be detected using the principle of electromagnetic induction, where a primary oscillating magnetic field induces eddy currents in the object, which in turn produce a secondary magnetic field that can be measured wi...

Detection and Characterisation of Conductive Objects Using Electromagnetic Induction and a Fluxgate Magnetometer (2022)
Journal Article
Elson, L., Meraki, A., Rushton, L. M., Pyragius, T., & Jensen, K. (2022). Detection and Characterisation of Conductive Objects Using Electromagnetic Induction and a Fluxgate Magnetometer. Sensors, 22(16), Article 5934. https://doi.org/10.3390/s22165934

Eddy currents induced in electrically conductive objects can be used to locate metallic objects as well as to assess the properties of materials non-destructively without physical contact. This technique is useful for material identification, such as... Read More about Detection and Characterisation of Conductive Objects Using Electromagnetic Induction and a Fluxgate Magnetometer.
