摘要

In its current configuration, IceCube is a formidable detector for supernovae. It can detect subtle featuresin the temporal development of MeV neutrinos from the core collapse of nearby massive stars. For a supernova atthe galactic center, its sensitivity matches that of a background-free megaton-scale supernova search experiment andtriggers on supernovae with about 200, 20, and 6 standard deviations at the galactic center (10 kpc), the galacticedge (30 kpc), and the Large Magellanic Cloud (50 kpc). Signal significances are reduced due to the noise floor andcorrelations between background hits. In this paper we discuss ways to improve the signal over background ratio withan improved data acquisition. We also discuss methods to track the average neutrino energy by multiple hit detec-tionfrom individual interacting neutrinos. The latter relies on the ability to reject coincident hits from atmospheric muons.
