Abstract

nEXO is a proposed tonne-scale neutrinoless double beta decay (0νββ) experiment using liquid ¹³⁶Xe (LXe) in a Time Projection Chamber (TPC) to read out ionization and scintillation signals. Between the field cage and the LXe vessel, a layer of LXe (“skin” LXe) is present, where no ionization signal is collected. Only scintillation photons are detected, owing to the lack of optical barrier around the field cage. In this work, we show that the light originating in the skin LXe region can be used to improve background discrimination by 5% over previous published estimates. This improvement comes from two elements. First, a fraction of the γ-ray background is removed by identifying light from interactions with an energy deposition in the skin LXe. Second, background from ²²²Rn dissolved in the skin LXe can be efficiently rejected by tagging the α decay in the ²¹⁴Bi-²¹⁴Po chain in the skin LXe.
