Vibration analysis and control of the LIGO observatories large chambers and support piers

Abstract

The Laser Interferometer Gravitational wave Observatories (LIGO) host kilometers long vacuum equipment. At each site, five large chambers and support structures are used to store the detector's core instrumentation. This article discusses the vibrations of these large vacuum chambers and equipment. It presents and summarizes transmissibility measurements performed at the LIGO test facilities and observatories. In addition, it presents detailed models and compares them with experiments and discusses vibration mitigation techniques and control options. It concludes with recommendations for future LIGO observatories.
