HEPS is a new generation synchrotron facility with a stringent requirement of very low emmittance. The key technology difficulties are supposed be overcome during the HEPS-TF stage. There are two projects in progress for mechanical and alignment system. One is the development of precision auto-tuning magnet girder, to meet the requirement of beam based alignment in tunnel, the other is the study on vibrating-wire alignment technique to improve alignment accuracy of magnets on a girder. This paper will describe the design and progress of both projects.

The magnet girder technology is one of the key tech-nologies which should be overcome in the stage of HEPS-TF (Test Facility of High Energy Photon Source). The girder should be beam-based aligned, and must has high adjusting precision and high stability as well. For these issues, two girder systems are designed and developed. This paper will describe the latest progress of the girder prototypes, including structure design updates, control system progress, and processing and assembling of Girder I prototype.

Abstract: There are stringent requirements on beam stability in the High Energy Photon Source (HEPS). The stability of the magnet girder is an extremely important factor for the beam stability. This paper will discuss the influence of ground vibration to the beam stability. This influence will determine the scope of the vibration magnification of the magnet girder. By improving the stiffness of the magnet girder, the influence will be reduced and the beam stability shall be improved. Besides, the progress of the HEPS-TF girder prototype and the vibration test will be described.

Magnet support system is important for CEPC. For the 100 km design of CEPC, there will be thousands of mag-nets and their supports in both collider and booster. Espe-cially, the booster ring is above the collider in the space, the magnets are hung by the supports. The goals of mag-net supports are simple and flexible structure, minimizing the magnet deformation, good stability, low cost and so on. This paper will describe the preliminary design of magnet support system, the optimization to minimize the magnet deformation and the topology optimization of the frame structure in booster.

To make the alignment become easier, the HEPS-TF (High Energy Photon Source-Test Facility) magnet girder, which is different from the conventional one, is designed to achieve the goal of adjusting the girder's position and orientation online. The control system is one of the key sub-part. This Paper will describe the control system design, especially on the hardware configuration, software programming as well as user interface design.
