Virgo seismic isolation system is composed by 10 complex mechanical structures named “Superattenuators”, or simply “Suspensions”, that isolate optical elements of Virgo interferometer from seismic noise at frequency larger than a few Hz. Each structure can be described by a model with 80 vibrational modes and is controlled by 24 coil-magnet pairs actuators. The suspension status is observed...
