Abstract:
Accelerometers were and are being developed to instrument the seismic attenuation chains of gravitational wave (GW) interferometric detectors. The main requirements of these instruments are strong directionality (>103 rejection of signal from orthogonal directions for feedback) and vacuum compatibility as well as high low-frequency sensitivity. Because of the directionality requirements, GW accelerometers tend to be more specialized for sensing of different degrees of freedom (horizontal, vertical, and tilt) than the classical geophysics seismometers but share several characteristics with these. The initial design of GW-dedicated accelerometers was inspired by geophysics instruments. Techniques developed for the GW field are now starting to spill over back into the geophysics field.
