Prof Nigel Spooner _ An overview of The Prescott Environmental Luminescence Laboratory (PELL)
- Date: Thu, 16 Mar 2023, 11:00 am - 12:00 pm
- Location: The Braggs lecture theatre
The Prescott Environmental Luminescence Laboratory’s focus is the environmental sensing of radiation and materials through luminescence. PELL has three major aspects: Geochronology, Radiation Sensing, and Novel Fluorescence.
Underwater Operations of an Atomic Magnetometer for Magnetic Anomaly Detection
- Date: Thu, 30 Mar 2023, 11:00 am - 12:00 pm
- Location: The Braggs Building, Level 2
Since the early part of the twentieth century highly-sensitive magnetometers have become a critical tool for detecting underwater objects through magnetic anomaly detection (MAD). Optically-pumped atomic magnetometers (OPMs) are an ideal candidate for operating in an underwater environment due to their ability to provide an absolute, scalar measurement of the local magnetic field. The University of Adelaide has been developing an OPM, based on non-linear magneto-optical rotation (NMOR) of polarisation, which has achieved a sensitivity of order 100 fT/rtHz at Earth’s field at relevant target frequencies, representing 20-fold improvement over existing MAD sensors.
