Abstract :
This article presents the results of ground motion measurements at DESY. Power spectral densities of vertical and horizontal ground motion were obtained in a frequency range from 0.003 Hz up to 140 Hz at some points of the HERA tunnel. The spectra of correlation were measured at a 30 m distance between seismic probes. Amplitudes of measured uncorrelated vibrations are compared with Linear Colliders tolerances
