Target - Place Where Reactor Neutrinos Get Detected

  • The inner layer is the target, which is filled with a scintillator infused with the element gadolinium.
  • When an antineutrino from the nuclear reactors interacts with a proton in this scintillator, it makes a neutron and a positron via the familiar beta decay process.
  • The positron moves through the scintillator and gives off light before annihilating with an electron to produce photons. Meanwhile, the neutron is absorbed by the gadolinium, releasing even more photons.
  • This array of photons provides a more defined neutrino signature than in previous experiments.
