Description
The planned next generation Enriched Xenon Observatory (nEXO) experiment is aiming to search for the neutrino-less double beta ($0\nu\beta\beta$) decay from $^{136}$Xe. nEXO has a sensitivity in the order of $10^{28}$ years on the half-life (T$_{1/2}$) of $0\nu\beta\beta$ decay from $^{136}$Xe after 10 years’ running, entirely covering the inverted mass hierarchy region. The nEXO detector is a time projection chamber (TPC). It has a cylindrical shape with a diameter of $\sim$1.3 m and a drift length of $\sim$1.2 m containing 5 tonnes of liquid xenon enriched to 90% ($^{136}$Xe). nEXO will use modular metal pads deposited on a quartz substrate to readout the ionisation signal and provide the spatial information of the event. nEXO will be implemented with $\sim$4 m$^2$ silicon photomultiplier (SiPM) to collect the scintillation light in addition to the charge signal. Combining both charge and light signals, nEXO aims to have an energy resolution of 1% at the Q-value of the double beta decay from $^{136}$Xe. In this talk, both the physics potential of nEXO and various R&D outcomes will be presented.
