- Abstract
- We present a novel inertial sensor designed and developed at Nikhef that features an interferometric readout for a horizontal monolithic accelerometer. It is the first time this class of mechanics and this type of optical readout √ are combined. It will be able to measure 3×10 −15 m/ Hz displacement levels from 20 Hz onwards. Current results show (self) noise √ levels of 8×10 −15 m/ Hz from 30 Hz onwards. Despite these unprecedented results, the result is worse than the sum of modeled noise contributions. Several possible unmodeled noise sources and possible solutions have been identified. Index Terms—Gravitational Waves, Accelerometer, Interfero- metric readout, Shot noise, Femtometer
