  The Shanghai Coherent Light Facility (SCLF) is a hard X-ray free electron laser facility under construction. It is designed to deliver photons from 400eV to 25keV at a repetition rate as high as 1MHz based on an 8GeV superconducting LINAC. The radiator section consists of two variable gap undulator lines and one superconducting undulator line. The main accelerator locates in the 3km tunnel, with 30m underground depths. The mechanical engineering, including the vibration on site ground and in the underground tunnel, the consideration of the tunnel sedimentation monitoring and compensation, as well as the structure design of the main components and it's support are described in this paper.

  Electron beam stability is very important for Shanghai Synchrotron Radiation Facility(SSRF). One of the major players on beam stability is the vibration stability of magnet support systems. This paper describes several kinds of hammerhead magnet support prototypes with different structures, materials and ground fixation. Modal and response analyses of these prototypes are contrasted by finite-element analysis(FEA) and tests. The design can be applied to guide and improve the mechanical structures and the stability of magnet support systems at SSRF and other light source facilities.

  For the third or fourth generation synchrotron light sources, the brilliance of the x-ray beam is 2 to 3 order higher than other generations, and in the meanwhile the beam emittance is at least one order smaller. To ensure the stability of the beam, the vibration caused beam motion is usually controlled to be within 10% of the RMS beam size. Thus the smaller beam emittance is, more restrict of the regulation plan to the vibration sources should be. Inside of the light source site, one major vibration source is the utility equipment such as water pump, compressors and so on. There are two controlling approaches for the vibration amplitude of those sources, one is damping, and another way is decay. However reasonable specification is the key of the controlling method. This work will present the detailed establish process of the regulation plan for HEPS in China.
