Description
Located at a distance of 30 m from the core of the Angra II 3.8 GW nuclear reactor in Brazil, the Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) uses fully depleted high-resistivity CCDs (Charge Coupled Devices) with the goal of measuring CEνNS of reactor antineutrinos with silicon nuclei. It has been taking data since 2016 with a noise level of less than 2 e- RMS and an active mass of ~50 g. CONNIE has demonstrated to be competitive in probing physics beyond the Standard Model by placing stringent constraints on simplified extensions with light mediators.
The experiment has recently been upgraded to host 2 skipper CCD sensors. It has been operating for ~2 months with these new generation detectors, achieving a noise of ~0.2 e- RMS.
Here, we report on the latest CONNIE results before the upgrade, we present the current status of the experiment and we give a future overview of the upcoming year operations.
