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…
