Description

The 11th ET symposium falls in a crucial phase of the Einstein Telescope project. The ET proposal has been submitted the 9th of September 2020 to the “2021 update of the ESFRI roadmap”. The European Strategic Forum for Research Infrastructures (ESFRI) roadmap describes the future major research infrastructures in Europe. The Einstein Telescope (ET) is the most ambitious project for a future terrestrial observatory for GWs. A consortium of European countries and of research institutions and universities in Europe has officially submitted the proposal for the realisation of such an infrastructure with the political support of five European countries, Belgium, Poland, Spain and The Netherlands, led by Italy. The European Gravitational Observatory (EGO) in Italy constitutes its transitional headquarters. The ET consortium brings together about 40 research institutions and universities in several European countries, including also France, Germany, Hungary, Norway, Switzerland and the United Kingdom.

The aim of the 11th ET symposium is twofold: expose the details of the submitted proposal (the technical, scientific and organisational achievements related to that crucial milestone will be presented), and initiate the first steps for the realisation of the international ET scientific collaboration. A first skeleton of the ET collaboration and organisation will be discussed with the participants and the scientific and technological challenges for the realisation of the Einstein Telescope will be presented.

Because of the COVID-19 constraints, the ET symposium will be fully remote. Zoom connection coordinates have been distributed to the registered participants; participation is open.

        CERN’s vacuum technology for the Einstein Telescope 20m

        CERN has competences in vacuum technology that can be useful for the Einstein Telescope (ET). Mechanical design, vacuum and electrodynamic simulation are regularly used and internally developed to support the early stage of conceptual design. In prototyping and production phase, surface treatments and coating are an important aspect of our activity. To assist studies and production, a large set of measurement techniques is operated, encompassing surface and chemical analysis. Measurement of functional vacuum properties is a core capability, from outgassing rate measurement, through thermal analysis, to pumping speed evaluation. Cost assessment and optimization are essential tasks when achieving large projects as the high-luminosity LHC and conceiving future accelerators.

        Sharing our experience in design, prototyping, construction, and operation of large vacuum systems might be profitable for the ET study at different level, and perfectly in line with the recent Update of the European Strategy for Particle Physics which calls for strengthening of synergies ‘in areas of common interest and mutual benefit’.
