Mirror Suspension Inertial Damping
Abstract
The suspension system for the VIRGO mirrors, the superattenuator, is characterized by low frequency high Q normal modes. The residual motion of the mirror associated to them must be reduced to lock the interferometer. A multidimensional active control system (the inertial damping) has been successfully implemented. The results are presented.
