The Daya Bay antineutrino detector filling system and liquid mass measurement
The Daya Bay Reactor Neutrino Experiment has measured the neutrino mixing angle [theta] sub(13) to world-leading precision. The experiment uses eight antineutrino detectors filled with 20-tons of gadolinium-doped liquid scintillator to detect antineutrinos emitted from the Daya Bay nuclear power pla...

| description | The Daya Bay Reactor Neutrino Experiment has measured the neutrino mixing angle [theta] sub(13) to world-leading precision. The experiment uses eight antineutrino detectors filled with 20-tons of gadolinium-doped liquid scintillator to detect antineutrinos emitted from the Daya Bay nuclear power plant through the inverse beta decay reaction. The precision measurement of sin super(2)2[theta] sub( 13) relies on the relative antineutrino interaction rates between detectors at near (400 m) and far (roughly 1.8 km) distances from the nuclear reactors. The measured interaction rate in each detector is directly proportional to the number of protons in the liquid scintillator target. A precision detector filling system was developed to simultaneously fill the three liquid zones of the antineutrino detectors and measure the relative target mass between detectors to |
