The facility is located in Zhanghai HighTech Park in Shanghai, with a total length of 3.1 km, consisting of three tunnels which are around 29 meters underground and 5 shafts. The 1st shaft is for injection, the 2nd shaft is for electron switches, the 3rd shaft is for beam dumps, the 4th shaft is the near experimental hall, while the 5th shaft is the far experimental hall. As such a long facility, the stability caused by the environmental vibrations is always a big concern. In this report, several vibration sensors, including accelerometers, seismometers, and velocity sensors were compared to find out the frequency range of the sensors. The vibration on the ground of the 1st shaft as well as underground were measured and analyzed. Furthermore, the ground vibrations were also compared with SSRF and SULF. To investigate the ground vibration effect on the beam transportation, the real vibration PSDs were imported into finite element analysis (FEA) model for random vibration analysis, the angular vibrations of the model were analyzed and tested.
