Description

Liquid xenon detectors have been widely used in dark matter direct detection experiments, in which nuclear recoil thresholds down to sub-keV have been demonstrated with ionization-only signal. A liquid xenon detector, using ionization-only approach, is also sensitive to sub-keV nuclear recoils from neutrino–nucleus coherent elastic scattering (CEvNS) off xenon nucleus. With a large cross section of CEvNS, a $\mathcal{O}(10)$ kg active target liquid xenon detector placed near a nuclear reactor is possible for detection of reactor anti-neutrinos via CEvNS. A mitigation of single-and-few electron backgrounds from impurities in liquid xenon and electrons trapped at the liquid-gas interface is necessary for a detection. This poster will present status of the NUXE experiment that is being designed to achieve sub-keV nuclear recoil threshold and low single-and-few electron background rate.
