For precise and uninterrupted measurements at extremely low temperatures, the Einstein Telescope (ET) requires vibration-free cooling. The consortium, consisting of Demcon kryoz, the University of Twente, and Cooll, is developing a solution based on sorption cooling, a principle already used in cryogenic microcoolers. The consortium is currently building vibration-free macro-format coolers, a technology that has never before been applied on this scale for cryogenic applications. With this development, the consortium is creating a unique value proposition in vibration-free cryocooler technology.

Vibration-free cooling for undisturbed measurements of gravity waves. A consortium of Demcon kryoz, Cooll and the University of Twente will develop an advanced cooling system for the Einstein Telescope. This enormous observatory will measure gravitational waves, which Albert Einstein predicted more than 100 years ago. It may be housed beneath the hilly landscape of the Dutch-Belgian-German border area. The consortium will receive 2.6 million euros over a period of three years from the R&D scheme for the Einstein Telescope, financed by the Dutch National Growth Fund. Vibration-free cooling to very low temperatures is necessary to detect the very weak signals from space. The three parties have a lot of fundamental knowledge and industrial expertise in vibration-free cooling. They are now using this to make the measurements much more accurate, for a better understanding of extreme events deep in the universe.
