Description
The Daya Bay Reactor Neutrino Experiment is being built to precisely measure the value of the neutrino mixing parameter $sin^2(2\theta_{13})$ to a sensitivity of 0.01 by comparing the relative flux of antineutrinos from reactor cores with antineutrino detectors at near and far distances. In an effort to control detector systematics to $<$0.4\%, detectors were designed to be as identical as possible. Extensive quality assurance measurements and simulation studies have been carried out to determine the expected level of similarity in physics response between detectors. We will discuss the design, fabrication, transportation, assembly, and quality assurance measurements for the detectors' acrylic target vessels, which contain the scintillating target region of the detector while maintaining optical clarity, mechanical stability, and low radioactivity. Mechanical, optical, radioactivity, compatibility and temperature- and UV-stability measurements carried out on the UVT acrylics, which are utilized in many past, current, and future neutrino and dark matter experiments, will also be recounted.
