A new exciting and profound question was brought up by the confirmation of neutrino oscillations: Can the source of the matter/anti-matter asymmetry of the universe be explained by CP violation in the neutrino sector? The answer to this fundamental question strongly depends on the magnitude of observable CP violation effects, which is, restricted by the size of the neutrino oscillation angle theta-13. The PI proposes a combined research and educational project focused on a highly sensitive search for a non-zero value of this neutrino mixing angle with the Double Chooz experiment. This experiment will measure, or significantly improve the upper limit on, the value of sin^2 (2theta-13) from 0.2, as measured by CHOOZ experiment, to 0.026.The PI proposes to build a multi-axis calibration system that will greatly enhance the precision of the measurement. Precise and comprehensive calibrations are critical to the minimization of systematic errors and the success of the Double Chooz experiment. The development, utilization and optimization of the articulated robotic arm system, and the analysis of the data obtained from the full volume calibration are all part of this five year research and education project. Besides providing an important augmentation for the Double Chooz experiment, the development of an articulated, robotic arm calibration system and its usage will also have important applications to future neutrino experiments where full target volume calibration systems will be of increasing importance. The PI is strongly committed to extending the scope of her research program to educate a broad range of students. A highly interactive multimedia web site that will introduce the physics of neutrinos and the Double Chooz experiment to high school students and their teachers as well as interested members of the general public will be designed and developed.

中微子振荡的证实提出了一个新的令人兴奋和深刻的问题：宇宙的物质/反物质不对称性的来源是否可以用中微子扇区中的CP破坏来解释？这个基本问题的答案很大程度上取决于可观测到的CP破坏效应的大小，这是由中微子振荡角θ-13的大小限制。PI提出了一个联合研究和教育项目，重点是通过双中微子实验高灵敏度地寻找中微子混合角的非零值。该实验将测量或显着提高sin ^2（2 theta-13）值的上限，从CHOOZ实验测量的0.2提高到0.026。PI建议建立一个多轴校准系统，这将大大提高测量的精度。精确和全面的校准对于最大限度地减少系统误差和成功进行双光子实验至关重要。关节式机械臂系统的开发、利用和优化，以及对全容积校准所获得数据的分析，都是这个为期五年的研究和教育项目的一部分。除了提供一个重要的增强双中微子实验，关节，机械臂校准系统的发展和使用也将有重要的应用，未来的中微子实验，全目标体积校准系统将越来越重要。PI坚定地致力于扩大她的研究计划的范围，以教育广泛的学生。将设计和开发一个高度互动的多媒体网站，向高中学生及其教师以及感兴趣的公众介绍中微子物理学和双中微子实验。
