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…
Cryogenic optical shadow sensors for future gravitational wave detectors
Amit Singh Ubhi, John Bryant, David Hoyland +1
Displacement sensors have a variety of applications within gravitational wave detectors. The seismic isolation chain of the LIGO core optics utilises optical shadow sensors for the…
Compact Michelson interferometers with subpicometer sensitivity
Jiri Smetana, Rebecca Walters, Sophie Bauchinger +11
The network of interferometric gravitational-wave observatories has successfully detected tens of astrophysical signals since 2015. In this paper, we experimentally investigate com…
