It is the distance the largest neutrino detector KamLAND (Kamioka Liquid Scintillator Anti-Neutrino Detector, Honshu island, Japan) has registered a decrease of the neutrino flow in the nuclear reactor antineutrino experiments [8]); see Figure 2 (the data are taken from [8]).
Reines in 1953 made the first of all attempt to detect anti-neutrino basing on the following nuclear reaction equation directly through interaction with matter method.
Heeger and his group at UW-Madison have been responsible for much of the design and development of the anti-neutrino detectors at Daya Bay.
Nonetheless, in 2005, this experiment, called KamLAND (short for Kamioka Liquid Scintillator Anti-Neutrino Detector), provided the first glimpse of geoneutrinos and a first approximation of uranium and thorium's contribution to the Earth's heat.
v], and k denote the four-momentum of the neutron, proton, electron, anti-neutrino, and photon, respectively--we denote the photon energy by [omega].
Researchers from the KamLAND or Kamioka liquid-scintillator anti-neutrino detector have reported evidence of neutrino oscillations.
KamLand, which stands for the Kamioka liquid scintillator anti-neutrino detector, measures neutrinos emitted by Japan's nuclear reactors.
