Description
nEXO is a 5 tonne liquid xenon (LXe) time projection chamber (TPC) that aims to detect neutrinoless double beta decay in $^{136}$Xe with a projected $90 \%$ CL half-life sensitivity of $1.35 \mathrm{x}10^{28}$ yr. nEXO will be able to measure energy deposits from both ionization electrons and scintillation photons from events that occur inside the detector. To achieve the required 10 ms electron lifetime goal, it is important to understand how detector materials affect the chemical purity of LXe. This talk will overview nEXO’s efforts to characterize the outgassing rates of different materials that are common in LXe TPCs as well as other candidate detector materials for nEXO.
