Design and sensitivity of a 6-axis seismometer for gravitational wave observatories

Leonid Prokhorov, Sam Cooper, Amit Singh Ubhi +13

We present the design, control system, and noise analysis of a 6-axis seismometer comprising a mass suspended by a single fused silica fibre. We utilise custom-made, compact Michel…

A vertical inertial sensor with interferometric readout

S. L. Kranzhoff, J. Lehmann, R. Kirchhoff +9

High precision interferometers such as gravitational-wave detectors require complex seismic isolation systems in order to decouple the experiment from unwanted ground motion. Impro…

Sensors and Actuators for the Advanced LIGO+ Upgrade

S J Cooper, C M Mow-Lowry, D Hoyland +6

As part of the Advanced LIGO+ (A+) project we have developed, produced, and characterised sensors and electronics to interrogate new optical suspensions. The central element is a d…

Active platform stabilisation with a 6D seismometer

Amit Singh Ubhi, Leonid Prokhorov, Sam Cooper +9

We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of…

ETpathfinder: a cryogenic testbed for interferometric gravitational-wave detectors

A. Utina, A. Amato, J. Arends +112

The third-generation of gravitational wave observatories, such as the Einstein Telescope (ET) and Cosmic Explorer (CE), aim for an improvement in sensitivity of at least a factor o…

Reducing controls noise in gravitational wave detectors with interferometric local damping of suspended optics

J van Dongen, L Prokhorov, S J Cooper +15

Control noise is a limiting factor in the low-frequency performance of the LIGO gravitational wave detectors. In this paper we model the effects of using new sensors called HoQIs t…
