Mitigating effects of nonlinearities in homodyne quadrature interferometers
Johannes Lehmann, Artem Basalaev, Jonathan J. Carter +12
Homodyne Quadrature interferometers (HoQI) are an interferometric displacement sensing scheme proven to have excellent noise performance, making them a strong candidate for sensing…
Testing Compact, Fused Silica Resonator Based Inertial Sensors in a Gravitational Wave Detector Prototype Facility
J J Carter, P Birckigt, J Lehmann +15
Future gravitational wave observatories require significant advances in all aspects of their seismic isolation; inertial sensors being a pressing example. Inertial sensors using gr…
Bilinear noise subtraction at the GEO 600 observatory
Nikhil Mukund, James Lough, Christoph Affeldt +8
Longitudinal control signals used to keep gravitational wave detectors at a stable operating point are often affected by modulations from test mass misalignments leading to an elev…
Control of a velocity-sensitive audio-band quantum non-demolition interferometer
S. S. Leavey, S. L. Danilishin, A. Gläfke +16
The Sagnac speed meter interferometer topology can potentially provide enhanced sensitivity to gravitational waves in the audio-band compared to equivalent Michelson interferometer…
Thermal Correction of Astigmatism in the Gravitational Wave Observatory GEO 600
Holger Wittel, Harald Lück, Christoph Affeldt +10
The output port of GEO 600 is dominated by unwanted high order modes (HOMs). The current thermal actuation system, a ring heater behind one of the folding mirrors, causes a signifi…
