江门中微子实验站位置测量方案设计与实施

Design and survey for the locating of Jiangmen underground neutrino observatory

为了对中微子质量顺序等前沿科学进行研究,江门中微子实验正在进行选址建设中。介绍了江门实验站与阳江核电站及台山核电站堆芯位置测量方案的设计与实施,采用GPS静态观测实现控制网的测量,并用LGO和自编软件对数据进行解算及坐标拟合转化。通过实际测量及数据解算,最终得到的坐标精度为±70 mm,满足设计要求,证明此次江门中微子实验站位置测量方案是合理可行的。

Background： In order to explore the sequence of neutrino mass and carry out other advanced scientific researches, Jiangmen underground neutrino observatory is proposed and the project is in the process of site searching. Purpose： This paper mainly introduces the way of position measurement between Jiangmen experimental station and reactor cores of Yangjiang nuclear power plant and Taishan nuclear power plant. Methods： The control network is established and measured by GPS, LGO and the self-developed software is used for data processing and fitting translation. Results： Through the actual measurement, the accuracy of the final coordinate is ±70 mm, which meets the tolerance requirement. Conclusion： According to the feedback from the designer, the scheme of the position measurement is reasonable and feasible.
