Towards a first design of a Newtonian-noise cancellation system for Advanced LIGO
Towards a first design of a Newtonian-noise cancellation system for Advanced LIGO
Newtonian gravitational noise from seismic fields is predicted to be a limiting noise source at low frequency for second generation gravitational-wave detectors. Mitigation of this noise will be achieved by Wiener filtering using arrays of seismometers deployed in the vicinity of all test masses. In this work, we present optimized …
