“…In the future, it will be used as an external reference for the comparison of the accuracy of the laser tracker and geometric leveling with the help of the hydrostatic leveling system at the site of Hefei Advanced Light Facility (HALF) [22,23]. Furthermore, the deformation prediction algorithm research is carried out based on years of particle accelerators' control network re-measurement data.…”

To ensure the long-term stability of the beam and further construction needs, it is necessary to re-measure the particle accelerator regularly. Since 2013, we have been measuring the HLS-II control network with laser trackers and the level for 10 years. Taking HLS-II as the object of study, we introduced the data acquisition strategy for the period of 2013–2023. We analyzed the horizontal and vertical deformation trends of each control point. In the vertical direction, we fused the geometric level and elevation data of the laser tracker network by using MC-GMM (a Gauss-Markov model which considers the uncertainty of Monte Carlo simulation). The analysis results show that, after the HLS upgrade, the annual average settlement of the ground control network tends to be stable. The settlement and horizontal variation of the device are all within a reasonable and controllable range. To ensure stability, accuracy, and efficiency in the measurement, we recommend employing the laser tracker for the re-measurement of the HLS-II storage ring. The data processing flow and methods mentioned in the article can provide a reference for deformation analysis of the upcoming construction of the Hefei Advanced Light Facility (HALF) and other large-scale metrology projects.

“…These effects need to be minimized to improve the performance of storage rings. For example, the dynamic aperture shrinkage caused by the sextupole field errors cannot be ignored in advanced third-generation light sources, future-ring based colliders and ultimate storage rings [1][2][3][4][5][6][7][8], where the nonlinear performance is very sensitive to the errors. So the work of the optimization of magnet sorting is in high demand for installation of magnets during the construction of a storage ring.…”

In this paper, the genetic algorithms are applied to the optimization problem of magnet sorting in an electron storage ring, according to which the objectives are set so that the closed orbit distortion and beta beating can be minimized and the dynamic aperture maximized. The sorting of dipole, quadrupole and sextupole magnets is optimized while the optimization results show the power of the application of genetic algorithms in magnet sorting.
