Gravitational wave detectors cooled with superfluid helium
GRAVITHELIUM addresses the central technology challenge in third generation gravitational wave (3G GW) detectors, proposing to cool the core optics of cryogenic detectors with superfluid helium. The Einstein Telescope (ET) will be the future European 3G GW observatory, designed to observe the whole Universe. It has entered the European ESFRI Roadmap in 2021 and is supported by the major international roadmaps. ET includes new technological challenges on the verge of feasibility, particularly in the cryogenic low-frequency interferometer (ET-LF) that is crucial to exploit the full scientific potential. Cryogenic operation of the ET-LF payloads at 10 K to 20 K is indispensable to suppress the…
