High Energy Photon Source (HEPS) has been constructed after decade of research. As the first diffraction-limited storage ring light source, many advanced devices are applied in this project, including the Beam Based Alignment Mover (Mover), which support and adjust the position of the Sextupole Magnet. It undertakes to remotely online adjust the position of Sextupole to meet the Physical requirement to correct the optics coefficient of Electron beam current. The positioning accuracy, attitude angle, and coupled error of Mover with 450kg load strictly proposed and tested during the development of Mover. There are three main types of Mover, including Four-layer with sliding guide, Three-layer with rolling guide, and Three-layer with sliding guide. This paper introduces the development and improvement of Mover.

  HEPS is a new generation synchrotron radiation source under construction in China. In order to complete high-precision installation of the 1.4km storage ring within a limited construction period, it is necessary to identify and solve potential issues in various aspects, including opera-tion space, installation process, alignment scheme, and unit transportation, prior to the regular batch installation. Therefore, a full-process installation experiment was performed and the feasibility of relevant schemes are verified. Batch installation is currently in progress based on the experimental experience.

  The HEPS storage ring comprises 48 7BA (seven-bend achromat) cells. There are 37 independent magnets in every cell, of which 5 dipoles are permanent magnets and the rest of magnets are all electromagnets including quad-rupoles, D-Q(dipole-quadrupole) combined magnets, sextupoles, octupoles and corrector magnets. These elec-tromagnets with small aperture and high magnetic field gradient should achieve high machining and assembly precision. In October 2023, all storage ring electromag-nets manufacturing have been completed. This paper mainly introduces the mechanical design, processing and assembly, and the manufacturing issues in the machining period.

  Very low emittance of High Energy Photon Source (HEPS) demands high stability and adjusting performance of the magnet support. The alignment error between girders should be less than 50 ¿m. Based on that, the adjusting resolution of the girder are required to be less than 5 ¿m in both transverse and vertical directions. Besides, the natural frequency of magnet support system should be higher than 54 Hz to avoid the amplification of ground vibrations. To fulfill the requirements, during the development of the prototype, the structure was designed through topology optimization, static analysis, grouting experiments, dynamic stiffness test and modal analysis, and the rationality of the structure was verified through prototype experiments. During the tunnel installation, the performance of the magnet support system was again verified to be better than the design requirements through test work after installation.
