Abstract:

Hydrostatic leveling system (HLS) is widely used in precision engineering survey, especially the alignment of particle accelerator, and the tidal effects on the measurement accuracy of HLS is non-ignorable, thus studies on tidal effects on the HLS is vital. A set of HLS was installed in Jingxian seismostation for verifying the methods to handle the tidal effects on the readings of HLS. Harmonic analysis of the data recorded by HLS and DSQ water tube clinometers in Jingxian seismostation and contrastive analysis of the results are completed. The tilt tide can be well reflected in the data of the both instruments and the results are both reliable. The reasons of the difference between the results are analyzed in this paper. Besides, a validation study based on the measurement data of the HLS used in SPring-8 storage ring for tidal correction on the reading of HLS is completed. The research establishes a foundation for HLS to be applied in micron-level precision alignment of particle accelerator in the future.
