Double Chooz detectors design
Résumé
The Double Chooz experiment aims at improving the current knowledge about the neutrino mixing angle Θ13, for which only an upper bound is known. For Θ13>0, it may be possible to observe leptonic CP violation included within the neutrino oscillation framework through a Dirac phase. As hadronic CP violation effects are too small to explain the apparent matter-antimatter asymmetry of the universe, leptonic CP violation is a promising candidate to be explored today. To surpass the accuracy of the CHOOZ experiment with a reactor $\overline nu_e$ experiment, higher statistics and reduced systematics are mandatory. The multidetector strategy chosen by Double Chooz will--in combination with well directed R&D and careful previous termdetectornext term construction--be able to achieve these requirements.
