CEν NS at reactor site with CONUS+ — •Janine Hempfling, Nicola Ackermann, Sophie Armbruster, Aurelie Bonhomme, Hannes Bonet, Christian Buck, Janina Hakenmueller, Gerd Heusser, Manfred Lindner, Werner Maneschg, Kaixiang Ni, Thomas Rink, Edgar Sanchez-Garcia, and Herbert Strecker for the CONUS collaboration — Max-Planck Institut fuer Kernphysik, Heidelberg, Germany
As a successor of the CONUS (COherent elastic NeUtrino nucleus Scattering) experiment CONUS+ aims for the detection of coherent elastic neutrino nucleus scattering with antineutrinos on a germanium target at a nuclear reactor. After the shut down of the Brokdorf nuclear reactor in 2021 the upgraded CONUS setup was moved successfully to a new site, the nuclear power plant in Leibstadt (Switzerland). CONUS+ is located at 21m distance from the 3.6 GWth reactor core and is equipped with the four former 1kg point-contact high-purity germanium detectors of CONUS which were optimized to achieve a significantly improved performance. Additionally, a second active muon-veto system is installed to improve the tagging of cosmogenic background. This talk will focus on the background characterization campaign at the new reactor site, the improvements of the detectors and the whole setup, the final installation and the first data-taking run of CONUS+.
