In this communication, recent advances on the design, development and experimental validation of fluorescent indicators for barium tagging in double beta decay reactions of Xe-136 to yield one Ba(2+)-136 cation plus two electrons will be presented. These developments include mono- and bicolor indicators. The components of the fluorescent sensors include a Barium catcher and a fluorophore,...
The pursuit of neutrinoless double beta decay (0νββ) detection stands at the forefront of particle physics research, promising profound insights into fundamental physics beyond the Standard Model. nEXO, a cutting-edge experiment, endeavors to explore this phenomenon utilizing a 5-tonne liquid xenon (LXe) time projection chamber (TPC), enriched to 90% in Xe136, poised to achieve a half-life...
Coating detector materials with films highly reflective in the vacuum ultraviolet (VUV) region improves sensitivity of the next-generation rare-event detectors that use liquid xenon (LXe). In particular, nEXO requires its Cu field-shaping rings and cathode to be coated by films that are 80% reflective at 175 nm, the mean wavelength of LXe scintillation. Other experiments, like DARWIN, could...
