Description
Since 2020, we have been continuing to conduct control surveys of the KEK electron-positron accelerator using a laser tracker and digital level. Since analysis has confirmed a trend in beamline fluctuations, we introduce an attempt to experimentally introduce a crack displacement meter to confirm the trend in fluctuations.
