Description
The CONUS experiment aims at detecting coherent elastic neutrino nucleus scattering (CE$\nu$NS) at the commercial nuclear power plant in Brokdorf, Germany. A high antineutrino flux is guaranteed at a distance of 17.1m to the reactor core with a maximum thermal power of 3.9GW$_{th}$. The recoils induced by the neutrinos are detected with four low energy threshold point-contact high-purity Germanium spectrometers enclosed in a shell-like shield design. An electron recoil threshold of ≤300eV is achieved.
The poster illustrates the analysis of the data sets collected in 2018 and 2019 to derive the first upper limit on CE$\nu$NS from the CONUS experimental data. This includes a detailed presentation of the relevant background sources, especially reactor-correlated and time-dependent backgrounds. The CONUS shield is capable to reduce the overall background at the shallow depth location of the experiment by more than four orders of magnitude. An outlook on improvements and upgrades towards a CE$\nu$NS detection in future runs is shown.
