Active seismic isolation for the AEI 10 m prototype interferometer — •Robin Kirchhoff — Albert-Einstein-Institute for gravitational physics Hannover, Germany

High precision measurements in various scientific fields suffer from seismic motion. Active seismic isolation is used to decouple the experiments from this disturbance. It is based on feedback control loops. The motion is measured by sensors and sent to actuators applying a counter force to reduce the motion. The poster explains the active seismic isolation of the AEI 10 m prototype interferometer. This is a testbed for large scale gravitational wave detectors. Different techniques to improve the isolation are introduced and the overall isolation performance is depicted.
