The Pacific Northwest National Laboratory has developed an Automated Radio-xenon Sampler/Analyzer (ARSA) for the Comprehensive Test Ban Treaty (CTBT) to measure four radio-xenon isotopes, 131mXe, 133mXe, 133Xe, and 135Xe, using a beta-gamma coincidence counting detector. Betas and conversion electrons are detected in a cylindrical plastic scintillation cell and gammas and x-rays are detected in a surrounding NaI(Tl) scintillation detector. A novel method to measure beta-gamma coincidences using a phoswich detector has been investigated.
