Research on ATL law based on hydrostatic leveling system

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.
