Modeling and Simulation of Vibration Isolation System for Large
... Seismic motion is an inevitable noise source for ground-based interferometric gravitational wave detectors. The continuous and random motion of the ground can excite the motions of the optical components of an interferometer, resulting in a displacement noise (seismic noise). In order to reduce the ...
