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

Within the upgrade of the IceCube neutrino detector new optical modules like the multi-PMT optical module (mDOM) are being developed, which are expected to significantly boost IceCube's performance in its main energy range from GeV to PeV and above. 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 enable the event-by-event detection of MeV neutrinos with a single module while at the same time keeping the background sufficiently low. The talk presents studies on the energy sensitivity for SNe neutrinos by using coincidences within and between mDOMs.
