Sensitivity of multi-PMT optical modules in Antarctic ice to supernova neutrinos of MeV energy
Abstract New optical sensors with a segmented photosensitive area are being developed for the next generation of neutrino telescopes at the South Pole. In addition to increasing sensitivity to high-energy astrophysical neutrinos, we show that this will also lead to a significant improvement in sensi...
