The R&D lab ETPathfinder is working diligently to develop the Einstein Telescope; this special telescope makes it possible to observe gravitational waves (ripples in spacetime) and thereby observe extreme events in the universe; think, for example, of the formation of black holes, the nature of neutron stars, and the universe’s structure just after the Big Bang.
Observing these events is complicated because they involve objects that emit little or no light. This is where the Einstein Telescope offers the solution. Measuring gravitational waves makes it possible to investigate hidden objects, offering valuable opportunities for studying the universe.

The telescope uses liquid nitrogen (LN2) to cool its radiation shields used for measurements in the low-frequency range. Demaco has been responsible for supplying the cryogenic infrastructures for this liquid nitrogen, including designing, manufacturing, and installing vacuum-insulated pipes (VIP) and specially designed subcoolers capable of supercooling liquid nitrogen to around 68 K.

We are proud to have contributed to this unique project and look forward to the insights the Einstein Telescope will bring to light in the coming years.
It’s all about Cryogenius.
