Description

The Daya Bay Reactor Neutrino Experiment expects to determine the neutrino mixing angle θ13 with a sensitivity of sin^2(2 θ13)=0.01 in a three-year run. Eight three-zone cylindrical Anti-neutrino Detector (AD) modules with Gd-doped Liquid Scintillator are arranged in two near halls and a far hall. In the outermost zone of each AD, 192 PMTs are mounted in the Mineral Oil (MO). The stability of the optical properties of the liquids is very important for controlling the systematic uncertainties of the experiment and thus will be monitored online. The design of a monitoring system for the MO and the results of the prototype will be presented.
