Daya Bay Antineutrino Detector
Photomultiplier tubes lining the walls of the Daya Bay neutrino detector. The tubes are designed to amplify and record the faint flashes of light that signify an antineutrino interaction. This experiment aims to measure the final unknown mixing angle that describes how neutrinos oscillate — another chapter in Brookhaven National Laboratory’s long history of neutrino research over the last several decades.
Brookhaven's chemistry and physics departments have major leadership roles in the Daya Bay experiment, from designing the detectors all the way through to analysis of the data gathered.
