Automated Calibration System for a High-Precision Measurement of Neutrino Mixing Angle $\theta_{13}$ with the Daya Bay Antineutrino Detectors

Understand

We describe the automated calibration system for the antineutrino detectors in the Daya Bay Neutrino Experiment.

• This system consists of 24 identical units instrumented on 8 identical 20-ton liquid scintillator detectors.
• Each unit is a fully automated robotic system capable of deploying an LED and various radioactive sources into the detector along given vertical axes.
• Selected results from performance studies of the calibration system are reported.
