Commissioning and characterization of a shadow sensor — •Vivek Pimpalshende1, Thomas Hebbeker2, Robert Joppe1,2, Tim Kuhlbusch1, Oliver Pooth1, Achim Stahl1, and Franz-Peter Zantis2 — 1III. Physikalisches Institut B, RWTH Aachen — 2III. Physikalisches Institut A, RWTH Aachen
The Einstein Telescope will be the first gravitational wave detector of the third generation. It will extend the detection sensitivity in the low frequency domain by more than an order of magnitude compared to current second generation detectors. An essential factor in achieving the sensitivity goals is to mechanically decouple the optic system from the ground. For this, a seismic isolation system is in place in the interferometric gravitational wave detectors. This talk will discuss one of the essential position sensors in this system: a shadow sensor.
Displacement sensors are a part of a control loop that monitors the relative motion of the components of the suspension system and controls the absolute motion of these components. This talk will present the commissioning of a shadow sensor along with its characteristics at room temperature.
