Seismic isolation of Advanced LIGO: Review of strategy, instrumentation and performance
Seismic isolation of Advanced LIGO: Review of strategy, instrumentation and performance
The new generation of gravitational waves detectors require unprecedented levels of isolation from seismic noise. This article reviews the seismic isolation strategy and instrumentation developed for the Advanced LIGO observatories. It summarizes over a decade of research on active inertial isolation and shows the performance recently achieved at the Advanced …
