A prototype stilbene beta cell has been designed, manufactured, tested, and compared to a plastic scintillator beta cell used for nuclear explosion monitoring of radioxenon. Measurements of the four isotopes of interest show similar responses for bot

Radioxenon detection is an important component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty. We developed and validated a new model in MCNPX-PoliMi to simulate the decay of various radioxenon isotopes and the detector resp

An algorithm was developed to improve the quantification of metastable isotopes in the presence of 133Xe. Radioxenon emissions are commonly used to monitor for nuclear explosions. When 133Xe is present in these samples it causes interference in the a

Radioxenon monitoring is one component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty. The systems in the field use hollow plastic scintillators for beta detection and NaI(Tl) detectors for gamma detection, where the plastic

Silicon detectors are of interest for the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) due to their enhanced energy resolution compared to plastic scintillators beta cells. Previous work developing a figure-of-merit (FOM) for comp

A stilbene crystal was coupled to a silicon photomultiplier (SiPM) to assess the performance of the detector's pulse shape discrimination (PSD) between fast neutrons and gamma rays. Pulses were digitized from a measurement of Cf-252 and digital charg
