The purpose of the measurement is to determine the levels of Ground Motion (GM) in experimental hall in synchrotron radiation facility SOLARIS. Ground motion in various areas, such as experimental hall, and a Linear Accelerator (LINAC) tunnel, are presented. Machines with high accuracy that are sensitive to ground vibrations are generally designed using crude assumptions on the dynamic properties of the floor where they are placed. This also holds for the prediction of machine accuracy in the design phase, based on expected or measured ground vibration spectra. It is well known that floor vibrations are one of the main disturbance sources for high precision equipment. Especially for equipment in the synchrotron radiation facility, like SOLARIS, but also in the other particle physics laboratory, the impact of floor vibrations on the machine accuracy is generally determining the dynamic architecture of the system. It is said that the peak around 0.3[Hz] in the GM spectra is caused by ocean waves. This phenomenon is shown by comparing GM spectra for the concrete floor in an experimental hall of SOLARIS with wave height of the ocean. Also 3rd Octave Band Analysis it was presented and corresponding Vibration Criteria were presented and discussed.
