Einstein Telescope Vacuum and Cryogenics Industrial Workshop: opportunities and challenges

Apr 21, 2026, 8:00 AM → Apr 22, 2026, 5:00 PM Europe/Zurich

30/7-018 - Kjell Johnsen Auditorium (CERN)

Carnita Hervet (CERN)

Registrations closes on Friday 27 March 2026

The purpose of the workshop is to bring together the leading institutes which are designing the vacuum and cryogenic systems of the Einstein Telescope (the third generation gravitational wave detector which is currently being designed in Europe) and European Big Science industries specialised in vacuum and cryogenic technologies, to discuss the challenges and opportunities ahead. The event will be held in CERN, where the ET vacuum pilot sector is housed. The technical challenges and aimed companies are available in the following link, and the topics for industry contribution in this link.

Registration fee is 85 CHF and includes coffee breaks and an evening aperitif at CERN on 21 April. We encourage participants to book accommodation at the CERN hostel. The rate is 62 CHF for a single room with bathroom.

Registration note (companies): Due to auditorium capacity limitations, we kindly ask each company to register no more than 2–3 representatives for this event.

Places for the visit to ET beampipe pilot sector and dinner will be limited and allocated on a first-come, first-served basis.

Thank you for your understanding.
