nEXO Pre-Conceptual Design Report

Understand

The projected performance and detector configuration of nEXO are described in this pre-Conceptual Design Report (pCDR).

• nEXO is a tonne-scale neutrinoless double beta ($0\nu\beta\beta$) decay search in $^{136}$Xe, based on the ultra-low background liquid xenon technology validated by EXO-200.
• With $\simeq$ 5000 kg of xenon enriched to 90% in the isotope 136, nEXO has a projected half-life sensitivity of approximately $10^{28}$ years.
• This represents an improvement in sensitivity of about two orders of magnitude with respect to current results.
