Unfolding of Supernova Neutrino Spectra in JUNO — •Max Büsken, Thilo Birkenfeld, Achim Stahl, Sivaram Yogathasan, and Shivani Ramachandran — III. Physikalisches Institut B, RWTH Aachen University

The Jiangmen Underground Neutrino Observatory (short: JUNO) currently under construction in southern China, is a 20 kt liquid scintillator neutrino detector. Its main physics goal will be to determine the neutrino mass hierarchy by measuring reactor neutrinos from two nuclear power plants at a baseline of 53 km. Apart from that JUNO will also be a great detector for neutrinos emerging from core-collapse supernovae. Recording such a signal would give a lot of insight into the physics of the collapse. Comprehensive simulations allow studying JUNO's potential detector response to the energy spectrum of supernova neutrinos. In this talk such simulations together with an identification of neutrino reaction channels are presented and a first approach to spectrum unfolding is shown.
