CONUS: Towards the detection of coherent elastic neutrino nucleus scattering — •Janina Hakenmüller for the CONUS collaboration — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

The CONUS experiment is located at the nuclear power plant of Brokdorf, Germany, at 17 m distance from the reactor core. Four high-purity point contact Germanium detectors with a noise threshold in the range of 300 eV have been deployed in an elaborate shield and are used to look for the elusive coherent elastic neutrino nucleus scattering. The experiment has been set up in 2018. The analysis of the first data set based on 1 month of reactor off time and 6 months of reactor on time will be presented.

Before the setup of the experiment, the location, especially the potential neutron-induced background, has been characterized thoroughly. It will be shown in the talk that inside the detector chamber no reactor thermal power correlated background is expected.

An outlook on planned upgrades and feasible physics goals with the CONUS setup will be given.
