	High Energy Photon Source (HEPS) has a strict restriction on vibration instabilities. To fulfill the stability specification, vibration levels on HEPS site must be controlled. The control standards are highly related with the vibration amplitude of the sources and the distance between sources and the critical positions. To establish reasonable regulations for new-built vibration sources, the decay patterns on ground are investigated on HEPS site for different frequency noises. A series of experiments were conducted using shaker to generate vibrations with frequency from 1Hz up to 100Hz. The vibration attenuation on ground and slab were measured using seismometers and the attenuation law were analyzed. Details will be presented in this paper.

	Funding: Supported by the National Natural Science Foundation of China (No.12105295) 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.

	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.

	TThe High Energy Photon Source (HEPS) is the first high-energy diffraction-limited storage ring (DLSR) light source to be built in China with natural emittance of few tens of picometer radian. Beam stability is critical for such an ultralow-emittance facility.

In this presentation, we report that the vibration levels on bare HEPS ground, the ground motion analytical model related with frequency, the designed site vibration specifications together with the careful consideration and basis. Also, the stable building design concepts, passive and active ways to minimize effects on the stability of the photon beam and critical accelerator and beamline components caused by ambient ground motion sources and the actual control effect will be introduced in detail.
