Technical challenges of the Einstein Telescope (general)

Zoom room (On-line)

The European physics and astronomy community wants to build a next generation gravitational wave detector: the Einstein Telescope. This detector will enable scientists to study parts of the universe that have never been observed before. It also comes with unique technical challenges that push the current state-of-the-art. In the coming three years we will invest more than 20 M€ on industry orders in the research facilities ETpathfinder and E-TEST to develop and test necessary new techniques. We are looking for industry partners who would like to join us in this challenge. That’s why we would like to invite you to a webinar and online discussion to explore the possibilities.

Outline of the programme:

Introductory webinar: Wednesday 1 July 15:00-17:00 (This meeting)

  • We will start the meeting with a general introduction of what it means to perform Gravitational Waves research and with some examples of co-development around advanced instrumentation. Then we will introduce several fields that require development or investment. After the introduction, there is some time for general questions.

Information & discussion: Wednesday 15 July 9:00-17:00 (Follow-up meeting two weeks later)

  • In the second meeting two weeks later, we organize a full day of one hour webinars per technological challenge with more technical information and discussion. You can attend any selection of sessions that are of interest to you.
  • for programme and registration per session.

Where: Online

For whom: Industry

About the Einstein Telescope and ETpathfinder

The Einstein Telescope is an advanced gravitational-wave observatory, currently in the planning stage. The border region between Belgium, Germany and the Netherlands is being considered as a possible location. This is because of its tranquility, stable ground and strong ecosystem of scientific institutions and high-tech companies. Currently an R&D-lab is being built in Maastricht: ETpathfinder. This lab will play a crucial role in the development and testing of technologies for the Einstein Telescope.
