The Daya Bay Reactor Neutrino Experiment discovered an unexpectedly large neutrino oscillation related to the mixing angle θ13 in 2012. The Daya Bay Reactor Neutrino Experiment discovered an unexpectedly large neutrino oscillation related to the mixing angle 13 in 2012. The Daya Bay reactor neutrino experiment [9] is being constructed by a large collab­ oration from Asia, North America, and Europe at the Daya Bay nuclear power plant in southeast China (near Shenzhen and Hong Kong). Accomplishing the experiment requires powerful reactors in a geological setting that allows for large underground neutrino detectors with significant overburden. The pool is lined with photomultiplier tubes to track any "stiff" (highly energetic) cosmic rays that make it all the way through the overlying rock. The observation of neutrino oscillation in experiments involving solar, atmospheric, accelerator, and reactor neutrinos has demonstrated that the masses of neutrinos are nonzero, and neutrinos with different flavors can mix with each other to form the mass eigenstates. The Daya Bay reactor neutrino experiment was designed to precisely measure the neutrino oscillation parameter θ 13 via the relative comparison of neutrino rates and spectra at different baselines. About the Daya Bay Experiment. This finding paved the way to the next generation of neutrino oscillation experiments. Accomplishing the experiment requires powerful reactors in a geological setting that allows for large underground neutrino detectors with significant overburden. The experiment is comprised of several an tineutrino detectors (such as shown above) that measure charge in 192 photomultiplier tubes and sensors distributed in cylindrical arrangement. The detectors rest in a pool being filled with ultrapure water. Coordinates. Available online 26 April 2016 .
