Study on supernova neutrino signals in JUNO — •David Stipp for the JUNO collaboration — JGU Mainz

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20*kt liquid scintillator neutrino detector currently under construction in Jiangmen (China). It will start operation in 2020. The primary goal is to determine the neutrino mass hierarchy in a medium baseline experiment with reactor antineutrinos.

JUNO will also be capable of detecting neutrinos from a galactic supernova burst. In the case of a core collapse supernova at a distance of 10*kpc, approximately 5000 electron antineutrinos will be detected via the inverse beta decay channel. This talk is about a Monte-Carlo study of how detector related uncertainties affect the determination of the mean supernova neutrino energy and the so-called "pinching parameter". The latter contains information on the spatial extension of the neutrino-releasing sphere in the supernova.

This work is funded by the DFG research unit "JUNO".
