GEO 600 triple pendulum suspension system: Seismic isolation and control
2000
Review of Scientific Instruments
In this article we describe aspects of the suspension system for each of the main optics ͑test masses͒ in the GEO 600 interferometric gravitational wave detector currently under construction in Germany. In particular we describe the triple pendulum, which is a key aspect of the overall system, discuss the details of the mechanical design, present transfer functions of the isolation performance, and display examples of impulse responses for the local control used to damp the low frequency modes
