【 摘 要 】

Registration of supernova neutrinos is one of the main goals of large underground neutrino detectors. We consider the possibility of using the large water veto tanks of future dark matter experiments as the additional facilities for supernova detection. Simulations were performed for registration of Cherenkov light in 2 kt water veto of Darkside-20k from high energy positrons created by supernova electron antineutrinos via inverse beta decay reaction. Comparison between characteristics of different supernova neutrino detectors are presented.
