The experiment utilized multiple interaction channels through which the presence of a neutrino (or in this experiment, an antineutrino) could be detected. The antineutrinos would enter a tank of water doped with cadmium chloride and interact with a water molecule's proton. This reaction ( p + + ν ν − − → → n 0 + β β + , where β β + represents a positron and ν ν − − represents an antineutrino) released positions which interacted with one of two adjacent tanks of liquid scintillator. The resulting photons could then be measured by photomultiplier tubes installed on the scintillator tanks. While this interaction occurs, the neutron product from the original reaction follows a random walk through the cadmium-doped water until it is absorbed in a cadmium atom. This process then produces more gamma rays, which are subsequently detected. The overall system therefore includes two pairs of simultaneously recorded events, the correlation of which in time provides strong evidence for an interaction involving a neutrino.
