Description
Summary:Charge Coupled Devices (CCD) are used for reactor neutrino experiments and already shown their potential in constraining new physics models. The prospect of a Skipper-CCD experiment looking for standard and beyond standard model physics (BSM) in a nuclear reactor has been recently evaluated for different benchmark scenarios. Here we report the installation of the first 2 g Skipper-CCD inside the containment building of a 2 GW\(_{th}\) nuclear power plant, positioned 12 meters from the center of the reactor core. We discuss the challenges involved in the commissioning of the detector and present data acquired during reactor ON and reactor OFF periods, with the detector operating with a sub-electron readout noise of 0.17 e-. The ongoing efforts to improve sensitivities to CEvNS and BSM interaction are also discussed.
