Wednesday, April 21, 2021 to Thursday, April 22, 2021 How the Daya Bay experiment helped China build a neutrino legacy In an underground laboratory near Shenzhen, southern China, officials gathered on 12 December 2020 to say goodbye to a decade-old ...
The Daya Bay Neutrino Experiment exists to pin that parameter down. Brookhaven Lab scientists and engineers led the Daya Bay collaboration''s detector engineering and design efforts. They perfected the "recipe" for the chemically stable liquid scintillator that fills the experiment''s particle detectors where the antineutrinos interact.
Now, the international team of physicists of the Daya Bay collaboration has reported the first result from the experiment''s full dataset—the most precise measurement yet of theta13, ...
Some friends and I visited Daya bay recently and I was very impressed with the area. There is a brand new hotel and beach resort, with restaurants and what appears to be continuing development with shopping and residential structures under construction. The town of Daya is a short drive away and the bay at that area is home to much more ...
