Experiment results show that the relative displacement measurement accuracy is better than 3 micrometer in 3-meter workpiece range, which can satisfy the real-time position feedback accuracy of the magnets in the process of ultra-high-precision pre-alignment. After two years of research and development, three pre-alignment standard workstations have been established. And the laser multilateration measurement method is adopted to the pre-alignment of the three, five and eight magnet girders in the storage ring of HEPS. Currently, 240 out of 288 girders have been pre-aligned after half a year of work.}}, }
