SN neutrinos with HALO-2

Stanley Yen

TRIUMF

A core-collapse supernova liberates 99% of its energy in the form of neutrinos of various flavors, each of which has a distinctive energy spectrum and time dependence. A lead-based detector would permit the observation of the electron neutrinos, and would be complementary to the water Cerenkov and organic scintillator detectors which are sensitive primarily to electron anti-neutrinos. We have tentative ideas for a 1 kiloton HALO-2 detector at Gran Sasso, as a followup to the much smaller HALO-1 now operating at SNOLAB.
