Alumni lecture 15 April 2021: Europe's next big research infrastructure

Albert Einstein predicted the existence of Gravitational Waves (GWs) in 1918, but only in 2015 a signal from a binary black hole merger was detected by the two LIGO detectors in the USA. This spectacular revelation provided many new insights about the Dark Universe and proved the need for even more technological advancement in this area. Future GW detectors might even promise a direct insight into the Big Bang!

One of the future GW detectors, the Einstein Telescope (ET), might be built in The Netherlands. The realisation of this mega-project brings together many types of engineers like physicists, chemists, civil and mechanical engineers, geologists, computer scientists, mathematicians and technology managers. 
One of them is TU Delft alumnus and instrumental researcher Joris van Heijningen. An important element of ET are the mirrors and to achieve precise measurements these need to be cooled down to 10 Kelvin while keeping them vibrationally quiet. To monitor the tiny vibrations in these cooled mirrors, Joris is developing a cryogenic superconducting sensor. He will share the technological aspects of ET and more challenges with cold sensors with you during this online alumni lecture.
