Description
Summary:Radioxenon detection is one of the four technologies used in the International Monitoring System to monitor for nuclear explosions around the globe. Currently deployed radioxenon detection systems detect the correlated beta and gamma-ray emissions from radioxenon isotopes using a hollow cell of plastic scintillator (so-called "beta cell") inside a well of sodium-iodide scintillator. Newly developed organic glass scintillators possess several properties that make them attractive for beta cells in radioxenon detectors, most notably good energy resolution, which would improve the sensitivity of systems deployed in the field. In this work we are developing an organic glass beta cell using a custom-built mold; we have developed CAD models for both the square- and rounded-cylinder designs, which will be cast and characterized to determine the energy resolution compared to the plastic scintillator that is currently used in the field. In the full paper, we will present the final beta cell prototype and results for its performance characterization, including light output and energy resolution.
