Seismometer Isolation for Noise Cancellation at 40m Interferometer

Document #:

LIGO-T1600263-v1

Document type:

T - Technical notes

Abstract:

LIGO detectors are extremely sensitive to low frequency seismic motion. At the 40 m Prototype Interferometer, we will test new adaptive noise cancellation techniques to reduce seismic noise in the detectors. This technology will be applied to the Advanced LIGO detectors to improve low frequency sensitivity to astrophysical events, and progress made on seismic cancellation will be used to adaptively reduce other noise sources, including audio and magnetic noise. This work involves development of enclosures for seismic sensors that isolate the instruments from external electro-magnetic and thermal fluctuations, to increase the sensitivity at very low frequencies.
