ET

The Einstein Telescope (ET) project aims at creating a third generation interferometric observatory for the detection of gravitational waves with a sensitivity at least ten times better than current detectors. The new observatory will be built underground on a site that is being identified between the two official candidates: Lula in Sardinia and Maastricht in the Netherlands.

To achieve the design sensitivity, the Einstein Telescope will develop a series of innovative technologies, including those necessary for the suspension and control of the interferometer mirrors, and those necessary for their cooling to cryogenic temperatures.

The international collaboration ET was born in 2022, including the main European countries. The site will be chosen in 2026, and the observatory will be completed by 2035.
