The Double Chooz antineutrino detectors

Understand

This article describes the setup and performance of the near and far detectors in the Double Chooz experiment.

• The electron antineutrinos of the Chooz nuclear power plant were measured in two identically designed detectors with different average baselines of about 400 m and 1050 m from the two reactor cores.
• Over many years of data taking the neutrino signals were extracted from interactions in the detectors with the goal of measuring a fundamental parameter in the context of neutrino oscillation, the mixing angle {\theta}13.
• The central part of the Double Chooz detectors was a main detector comprising four cylindrical volumes filled with organic liquids.
