Description
Low-frequency electric field detection remains a significant challenge for conventional antenna-based sensors due to their large size and limited sensitivity. Rydberg atom–based vapor-cell sensors offer a promising alternative for quasi-DC electric field sensing; however, their performance is constrained by electric-field screening arising from charge accumulation within the cell. I will be presenting results from our set-up using Rydberg atoms for sensing and investigating the impact of different vapour cell materials and coatings on the screening rates and on enhancing overall sensor performance. Furthermore, we are investigating a cavity-enhanced setup where modelling predicts an improvement in sensitivity by up to 20 dB compared to free-space measurements. Our results will enable high sensitivity detection quasi-DC electrometry assuming optimised cell coatings within the cavity-enhanced configuration.
