Description
nEXO is a next-generation 5 tonne homogeneous liquid xenon time projection chamber(TPC) which seeks to detect neutrinoless double beta decay($0\nu\beta\beta$) decay in $^{136}$Xe. The experiment will use the combination of scintillation and ionization signals to reconstruct events with an energy resolution of $<$1% $\sigma/E$ at the $0\nu\beta\beta$ Q-value of $2.5$MeV. It is projected to reach $0\nu\beta\beta$ half life sensitivity of $1.35 \times 10^{28}$yr in 10 years of data taking which will provide a search for lepton number violating processes with 2 orders of magnitude higher sensitivity than existing experiments.Active R&D is ongoing to optimize the design of nEXO, minimize its residual radioactivity budget and optimize novel ionization charge and scintillation light readout techniques. In this talk I will give an overview of the experiment and cover about recent R&D work by nEXO-Collaboration for nEXO design.
