Ground motion measurements in HERA
Proceedings Particle Accelerator Conference
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.
