Sensitivity of multi-PMT optical modules to the energy spectrum of MeV supernova neutrinos — •Florian Sprenger, Cristian Jesús Lozano Mariscal, Lew Classen, and Alexander Kappes for the IceCube collaboration — Westfälische Wilhelms-Universität Münster, Institut für Kernphysik, Münster

Within the efforts for the next generation neutrino observatory at the South Pole, new optical modules like the multi-PMT optical module (mDOM) are being developed, which are expected to significantly increase the detector sensitivity to high energy astrophysical neutrinos. On the other hand, neutrinos from core-collapse supernovae with energies as low as few MeVs can reveal a detailed picture of the events that accompany the collapse of the core and verify and enhance our picture of these powerful explosions. With its unique features like local coincidences and information on the arrival direction of detected photons, the mDOM may allow for event-by-event detection of MeV neutrinos with a single module while at the same time keeping the background sufficiently low. The talk presents the first study on the energy sensitivity for SNe by using local coincidences in the mDOM.
