Description
Measurements of radioactive noble gases, i.e. isotopes of xenon and argon, are an important part for an on-site inspection (OSI) in detecting an underground nuclear explosion. The first integrated field exercise where the capacity to collect and analyse noble gases exercised was in Jordan in 2014 (IFE14). Since then, the development of methods and systems has improved the capacity for xenon detection. Here, details on the SAUNA Field system are presented, including a rapid deployment configuration (in a flight pod), integration with the OSI software and routines (GIMO) and an automatic inlet. The latter allows for multiple samples to be added simultaneously to the system and at the same time freeing time for the OSI inspectors. These features were tested during the build-up exercise field test in Hungary in 2024 (BUE24). Lesson learned from this, and earlier field measurements, as well as potential improvements for collection and analysis of noble gas during an OSI will be presented.
