First Demonstration of Electrostatic Damping of Parametric Instability at Advanced LIGO
Carl Blair, Slawek Gras, Richard Abbott +16
Interferometric gravitational wave detectors operate with high optical power in their arms in order to achieve high shot-noise limited strain sensitivity. A significant limitation…
The Advanced LIGO Input Optics
Chris Mueller, Muzammil Arain, Giacomo Ciani +18
The Advanced LIGO gravitational wave detectors are nearing their design sensitivity and should begin taking meaningful astrophysical data in the fall of 2015. These resonant optica…
Seismic isolation of Advanced LIGO: Review of strategy, instrumentation and performance
F. Matichard, B. Lantz, R. Mittleman +49
Isolating ground-based interferometric gravitational wave observatories from environmental disturbances is one of the great challenges of the advanced detector era. In order to dir…
Advanced LIGO Two-Stage Twelve-Axis Vibration Isolation and Positioning Platform. Part 1: Design and Production Overview
Fabrice Matichard, Brian Lantz, Kenneth Mason +37
New generations of gravity wave detectors require unprecedented levels of vibration isolation. This paper presents the final design of the vibration isolation and positioning platf…
Advanced LIGO Two-Stage Twelve-Axis Vibration Isolation and Positioning Platform. Part 2: Experimental Investigation and Tests Results
Fabrice Matichard, Brian Lantz, Kenneth Mason +37
This paper presents the results of the past seven years of experimental investigation and testing done on the two-stage twelve-axis vibration isolation platform for Advanced LIGO g…
Global Feed-Forward Vibration Isolation in a km scale Interferometer
Ryan DeRosa, Jennifer C Driggers, Dani Atkinson +5
Using a network of seismometers and sets of optimal filters, we implemented a feed-forward control technique to minimize the seismic contribution to multiple interferometric degree…
