@article{ref1, title="Introducing the MARGOT prototype: an ultra-compact and mobile gas detection system for nuclear explosion monitoring", journal="Applied radiation and isotopes", year="2019", author="Thomas, V. and Delaune, O. and Cagniant, A. and Le Petit, G. and Fontaine, J-p", volume="152", number="", pages="91-100", abstract="An ultra-compact and unshielded spectrometer for analysis of atmospheric radioxenons has been developed. This system works at ambient temperature and has a 58 cm3 inner active volume. Atmospheric radioxenons activities are determined with electron/photon coincidence technique using both NaI(Tl) detector and large pixellized Si-PIN detector. The performances of the detection system without shielding in terms of Minimal Detectable Activities are below 65 mBq for a 12 h acquisition, for all radioxenons of interest. An enhanced version of the prototype presented here is already under development: the Mobile Analyzer for Radioactive Gases OuTflows (MARGOT) system.
