Double Chooz detectors design

摘要

The Double Chooz experiment aims at improving the current knowledge about the neutrino mixing angle Θ_(13), for which only an upper bound is known.rnFor Θ_(13) ＞ 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.rnTo surpass the accuracy of the CHOOZ experiment with a reactor v_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 detector construction—be able to achieve these requirements.
