A High Precision Measurement of $\theta_{13}$ with the Daya Bay Antineutrino Detectors

The Daya Bay Reactor Neutrino Experiment is being built to measure short-baseline electron antineturino disappearance at the Daya Bay nuclear reactor complex in southern China. Eight antineutrino detectors placed at different distances from the reactor cores will measure antineutrino flux and energy spectrum via inverse beta decay reactions on protons. Using this information, the experiment aims to identify the final neutrino mixing angle $\theta_{13}$ with a sensitivity of $\sin^{2}2\theta_{13} < .01$ at 90\% CL. As the Daya Bay sensitivity will ultimately be limited by detector-related systematics, understanding detector performance and identicalness will be crucial to meeting experimental goals. This talk will present the physics principles used in and the design of the detectors, the expected detector performance, an explanation of AD systematics, and the current status and future plans of the experiment.
