Because neutrinos are so penetrating, they allow a nearly-unobstructed view of the nuclear, particle and astrophysical processes occurring deep in the interiors of the Sun and stars. Already a spectacular object at optical wavelengths, 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. Neutrinos is where the action is! A neutrino detector constructed of lead would be primarily sensitive to the electron-type neutrinos from a supernova, and would complement the existing water Cerenkov and organic scintillator detectors which are sensitive primarily to electron anti-neutrinos. We have tentative ideas for a 1 kiloton lead detector at the Gran Sasso laboratory in Italy, as a successor to the much smaller HALO-1 detector now operating at SNOLAB in Canada. We would welcome new collaborators.
