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…
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…
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…
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…
