Description
The Einstein Telescope (ET) is the European third-generation gravitational-wave observatory currently under development.
It includes a low-frequency (LF) and a high-frequency laser interferometer.
In comparison to existing detectors, sensitivity improvements of several orders of magnitude are foreseen.
Cryogenic operation of ET-LF is imperative for exploiting the full scientific potential of ET, with mirrors operated at temperatures of 10 K to 20 K in order to reduce the thermal noise.
We present our developments for a cryogenic infrastructure and a novel payload cooling concept for ET-LF based on the application of superfluid helium.
