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…
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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Integration of high-performance compact interferometric sensors in a suspended interferometer
Alexandra Mitchell, Johannes Lehmann, Philip Koch +6
Homodyne Quadrature Interferometers (HoQIs) are compact, low noise and high dynamic range displacement sensors designed for use in gravitational wave observatories. Their lower noi…
Multi-scale optimal control for Einstein Telescope active seismic isolation
Pooya Saffarieh, Nathan A. Holland, Michele Valentini +6
We present a multi-scale optimal control framework for active seismic isolation in the Einstein Telescope, a third-generation gravitational-wave observatory. Our approach jointly o…
