Title: GADZOOKS! Anti-neutrino spectroscopy with large water Cherenkov detectors

Journal Article · · Phys.Rev.Lett.

We propose modifying large water \v{C}erenkov detectors by the addition of 0.2% gadolinium trichloride, which is highly soluble, newly inexpensive, and transparent in solution. Since Gd has an enormous cross section for radiative neutron capture, with $$\sum E_\gamma = 8$$ MeV, this would make neutrons visible for the first time in such detectors, allowing antineutrino tagging by the coincidence detection reaction $$\bar{\nu}_e + p \to e^+ + n$$ (similarly for $$\bar{\nu}_\mu$$). Taking Super-Kamiokande as a working example, dramatic consequences for reactor neutrino measurements, first observation of the diffuse supernova neutrino background, Galactic supernova detection, and other topics are discussed.
