The Daya Bay reactor neutrino experiment is designed to measure the last unknown neutrino mixing angle with a sensitivity of sin22θ13<0.01 by measuring the flux and spectrum of reactor antineutrinos at varying distances from the Daya Bay nuclear power plant. The experiment will use eight identical liquid scintillator detectors with 20-ton target mass each at distances ranging from 0.3-2 km from the power plant. A novel concept of this oscillation search is the relative measurement of the antineutrino flux between multiple, identical detectors. To achieve the experimental sensitivity relative detector systematics will be controlled to <0.4%. We will describe the design and construction of the Daya Bay antineutrino detectors and experimental methods for the control of the detector-related systematic uncertainties.
