Description
The nEXO experiment is a proposed next-generation liquid xenon experiment to search for neutrino-less double beta decay ($0\nu\beta\beta$) of $^{136}$Xe. The experiment will use a 5-tonne liquid xenon monolithic time projection chamber enriched to 90% $^{136}$Xe. Ionization electrons and scintillation photons from energy deposits in the detector will recorded by a segmented anode and a large area SiPM array. This talk will present recent progress in the detector design, an improved modelling of signal readout and the development of a deep neural network based data analysis architecture to improve signal/background separation. These developments result in a 90% CL $0\nu\beta\beta$ halflife sensitivity of 1.35$\times$10$^{28}$ yrs in 10 years of data taking.
