High precision measurement (or low upper limit) of the neutrino mixing angle theta13 is strongly dependent on the measurement uncertainty. Double Chooz goal is the total uncertainty of just 0.6%, which is unprecedented level of precision in the earlier reactor neutrino experiments. CHOOZ experiment has the lowest total uncertainty to date of 2.7%, while Bugey was the only reactor experiment that built 2 identical detectors, achieving 2% relative and 5% total uncertainty. Extensive calibrations are essential in achieving low uncertainty goal of Double Chooz. In my presentation, I will describe the full volume calibration system for Double Chooz and its role in achieving low systematic errors, toward the high precision measurement (or low upper limit) of theta13.
