Description
The coherent elastic neutrino-nucleus scattering (CEνNS) phenomenon, as predicted by the Standard Model, was initially observed in 2017 by the COHERENT collaboration. The detection of CEνNS, characterized by a significantly higher cross-section compared to the inverse beta decay (IBD), has introduced a novel and potent approach for reactor monitoring, nuclear structure exploration, neutrino property investigation, and exploration of new physics beyond the standard model. Currently, various experimental technologies are being developed to detect CEνNS from reactor neutrinos. Among these technologies, the dual-phase argon detector with a low detection threshold down to sub-KeVnr is of particular interest for observing CEvNS from reactor neutrinos. Our proposal entails the deployment of a hundred-kilogram dual-phase argon time projection chamber detector, positioned 35 meters away from the Taishan reactor in Guangdong, China. In this presentation, we will outline the anticipated event rate for CEνNS detection by utilizing underground argon and optimizing the background veto strategy. Furthermore, we will provide an estimation of the detector's sensitivity to measure neutrino properties, based on its preliminary design.
