Research on ATL law based on hydrostatic leveling system

National Synchrotron Radiation Laboratory, University of Science and Technology of China, Hefei 230026, China

摘要

摘要: 针对粒子加速器，地面变形会导致束流畸变甚至丢失，所以在粒子加速器领域对地面变形的研究是有必要的。通过在合肥光源直线加速器隧道先后搭建两套并行分布、由7台间隔10 m的静力水准传感器构成的静力水准系统，经过对两套系统采集的共计三段为期半个月监测数据进行分析，发现了ATL模型中存在的线性关系，分别得到不同时段本地区模型常数值，并发现了模型常数与季节温度的相关性。最后通过数据对比发现地面点相对运动中的周期成分主要受固体潮效应影响。

Abstract: For particle accelerators, ground deformation can cause beam distortion or even loss, so it is necessary to study ground deformation in particle accelerator field. By constructing two parallel distributed hydrostatic leveling systems consisting of 7 static leveling sensors spaced 10 m apart in the Hefei Light Source’s linear accelerator tunnel, this paper analyzed a total of three monitoring data collected by the two systems for a period of half a month, find the linear relationship present in the ATL law and obtain the constant values of the ATL law separately, and discover the correlation between the model constant A and seasons’ temperature. Finally, through data comparison, it was found that the periodic components in the relative motion of ground points are mainly affected by the earth tide.
