DYB Reactor Neutrino ExperimentDYB Reactor Neutrino Experiment

• 中微子是构成物质世界的最基本单元。已发现的中微子振荡有两种。• 目的：寻找中微子的第三种振荡，用 13 表示。• 意义： 13 的大小决定了未来中微子物理研究的发展方向。• 用大亚湾反应堆测量 13 是我国粒子物理发展的一个重大机遇：

功率高（世界第二）、周围山体屏蔽宇宙线本底、造价较低• 难点：精度较过去提高一个量级。• 我们的突破：独特设计 + 环境优势 达到精度要求。

12

– 通过远近点之间的相对测量提高精度。– 同一点的多模块中微子测量以降低系统误差并相互校验。– 多重宇宙线反符合探测器提高效率，降低系统误差。

• From the press release:• The copious data revealed for the first time the strong

signal of the effect that the scientists were searching for, a so‑called “mixing angle” named theta one-three (written θ13), which the researchers measured with unmatched precision. The Daya Bay collaboration’s first results indicate that theta one-three, expressed as sin2 2 θ13, is equal to 0.092 plus or minus 0.017.

• “This is a new type of neutrino oscillation, and it is surprisingly large,” says Yifang Wang ……….

15

• “The Daya Bay experiment plans to stop the current data-taking this summer to install a second detector in the Ling Ao Near Hall, and a fourth detector in the Far Hall, completing the experimental design,” says Yifang Wang.
