SUMMARY:Qing Shilo Xia (Yale) "Hunting for neutrinoless double beta decay with liquid xenon detectors"
DESCRIPTION:Abstract:  \n\nLiquid xenon (LXe) is employed in a number of current and future detectors for rare event searches. In this talk\, I will present the latest results from EXO-200\, which searched for neutrinoless double beta decay (0υββ) in Xe-136 between 2011 and 2018. I will also present a measurement of the absolute scintillation and ionization response generated by MeV energy gamma sources over a range of electric fields in EXO-200. These measurements are useful for simulating the performance of future 0υββ detectors employing LXe\, such as nEXO\, which is a next generation 0υββ experiment using Xe-136 aiming to reach a half-life sensitivity ~10^28 years. nEXO will require ultra-low radioactivity\, high-speed cabling to carry digital signals from in-LXe electronics. I will describe the development of high-bandwidth digital cable prototypes with sufficiently low radioactivity for use in the experiment. While designed specifically for nEXO\, the demonstration of radiopure high-bandwidth cabling and interconnection techniques is relevant for many next-generation rare-event searches with large channel counts and high-speed digital electronics.
