Test setup for cryogenic sensors and actuators working towards the Einstein Telescope — •Robert Joppe, Matthias Bovelett, Tim Kuhlbusch, Thomas Hebbeker, Vivek Pimpalshende, Oliver Pooth, Achim Stahl, Jan Wirtz, Franz-Peter Zantis, and Markus Bachlechner — RWTH Aachen, Aachen, Deutschland

The Einstein Telescope will be the first gravitational wave detector of the third generation. The sensitivity goal, especially in the low frequency region, will be achieved among other improvements by cooling the main parts of the interferometer. The required electronic components, sensors and actuators needed for mirror alignment and active dampening of suspension resonances have to perform at cryogenic temperatures.

In this poster we will present our work on electronics and mechanics within the E-TEST project. Furthermore the performance of our cryogenic UHV test setup will be explicated.
