SILENT : Seismic isolation of the Einstein Telescope

Visit the website of this project

Measuring gravitational waves remains a challenge, because the seismic activity of the earth itself can interfere with the signal. In the SILENT (Seismic IsoLation of EinsteiN Telescope) project, researchers are working on an incredibly stable platform that ‘floats in space’ and special sensors that can help distinguish the gravitational wave signal from noise. To achieve this, three important innovations will be combined: new optical inertial sensors, special efficient control systems and direct measurement of Newtonian noise.
