Dutch government embraces plans for Einstein Telescope in border region South-Limburg

The Dutch government intends to conditionally allocate 42 million euros from the Dutch National Growth Fund to the Einstein Telescope, and is also reserving 870 million euros for a future Dutch contribution to the construction. This decision was taken by the Dutch government based on the advice of the Advisory Committee of the National Growth Fund. With this decision, the Cabinet gives an enormous boost to Dutch science and to the broad development of the South Limburg border region.

The intended investment of 42 million euros will go towards preparatory work such as innovation of the necessary technology, location research, building up a high-tech ecosystem and organisation. With the reservation of the 870 million, the Netherlands has an excellent basis to apply in the future, together with Belgium and Germany, for the realisation of the Einstein Telescope in the border region of South Limburg.

The Cabinet however does ask for a further explanation of the valorisation strategy of the scientific project. The initiators are also asked to further elaborate the plan for monitoring and evaluation of the project. The partners involved will of course work to meet these conditions timely.

The proposal for granting money from the National Growth Fund to the Einstein Telescope was submitted on 31 October 2021 by the Minister of Education, Culture and Science (OCW), with the support of the colleague from Economic Affairs and Climate Policy (EZK).

National Institute for Subatomic Physics Nikhef, the Province of Limburg and regional development agency LIOF jointly drew up the growth fund proposal last year, supported by the Ministries of OCW and EZK. Nikhef director Stan Bentvelsen has been involved with the Einstein Telescope for years. He is delighted, but also sees that there is still a lot of work to be done: “It is fantastic that the cabinet embraces the ambition to make the Netherlands a world leader in research into gravity waves. These Growth Fund resources form the basis for further cooperation with our partners in Germany and Belgium and for research into the geological subsurface in the border region of South Limburg. A major project requires a careful process, and we are putting our heart and soul into it. I am confident that we will meet the additional conditions.”

Stephan Satijn, Provincial Executive member for Limburg, is very enthusiastic about the opportunities that the possible arrival of the Einstein Telescope offers for the Netherlands and Limburg.

“With today’s decision, the Cabinet places our country at the global forefront of high-tech and science. Limburg is the logical place to help shape this leading position. Not only because of the suitability of our soil for the Einstein Telescope, but also because we are accustomed like no other to working together internationally and to connecting science and business. I am pleased and proud that the government recognises the value of Limburg and is helping to increase it further with such a substantial investment. In addition to direct orders for companies, the Einstein Telescope gives Limburg and the Netherlands a unique lead in knowledge, expertise and innovative technologies that can be marketed by existing or new companies. This is essential for the economic development of the Netherlands in the medium and especially the long term.”

About the Einstein Telescope

The Einstein Telescope is a future underground observatory for measuring gravitational waves. Powerful laser beams will soon bounce between deep-cooled, vibration-free mirrors at the ends of kilometre-long vacuum tunnels. The instrument will be much more sensitive than existing detectors. As a result, it can detect many more sources and scan a volume of the universe thousand times larger. Researchers will use this instrument to look for instance for the precise structure of neutron stars, the birth process of black holes and the structure of the universe immediately after the Big Bang.

The border region of South Limburg – the Euregio Meuse-Rhine – is one of the possible locations for this observatory. Housing the Einstein Telescope in this region could have a major positive impact on science, the economy and society in the Netherlands. With the committed investments from the National Growth Fund, the Netherlands has the basis to join forces with Belgium and Germany to establish a strong candidacy in 2024/2025.

This is a joint press release of National Institute for Subatomic Physics Nikhef, Province of Limburg and regional development agency for Limburg LIOF.


Grenzlandkonferenz 2022

On 31.03.2022, the 4th German-Dutch GrenzLands Conference will take place in the Aachen Coronation Hall. During the conference, new goals of cross-border cooperation will be presented and a balance sheet of the past years will be drawn up. Thematically, the GrenzLands Conference will be based on the contents of the North Rhine-Westphalia – Dutch Borderlands Agenda. Due to the geographical location of Aachen and the Euregio Meuse-Rhine, the conference will also include elements of tri-national cooperation.

For this reason, a side event on the Einstein telescope will take place in the context of the GrenzLands Conference, with the aim of involving representatives of German politics just as closely in the preparatory activities and to consider the establishment of a German task force in the future.

The GrenzLands Conference 2022 will take place face-to-face.

On the conference, an award for special commitment to cross-border cooperation will be presented again this year. You can find the call here. Call for the Border Region Award 2022


Conférence Wallonne télescope Einstein

18/03/2022 – Liège Science Park, Liège

Le Télescope Einstein est un projet européen de grande infrastructure scientifique, qui a pour objectif de créer le plus grand observatoire mondial en matière de détection d’ondes gravitationnelles (d’infimes soubresauts de l’espace-temps) afin de mieux comprendre la théorie du big bang et les origines de l’Univers.

L’infrastructure consistera en trois paires d’interféromètres géants, longs chacun de 10km, disposés en triangle, et enfouis entre 200 et 300 mètres de profondeur. 
Plusieurs sites d’implantation en Europe sont envisagés, parmi lesquels la région des Trois Frontières, au cœur de l’Euregio Meuse-Rhin, à cheval sur les frontières belge, hollandaise et allemande. La décision sur la localisation serait prise en 2025.

En attendant, l’Euregio Meuse-Rhin se prépare, à travers plusieurs projets financés et en cours (E-TEST, ETpathfinder, ET2SMEs), permettant d’étudier par exemple les sous-sols de manière approfondie, de développer un grand miroir suspendu à température cryogénique (un projet unique au monde qui sera développé au CSL à Liège) et des technologies pour améliorer l’observation des ondes gravitationnelles. 

Prédites par Albert Einstein et observées pour la première fois en 2015, les ondes gravitationnelles marquent les débuts de la révolution de l’astronomie gravitationnelle, et d’une nouvelle physique pour aller plus loin dans la compréhension des origines et de l’évolution de notre Univers. 

Le Télescope Einstein est un énorme projet scientifique qui pourrait prendre place partiellement en Wallonie. Il offre des opportunités importantes et très stimulantes pour les chercheurs mais aussi les entreprises technologiques des régions concernées, tout en constituant un indéniable facteur d’attraction, à l’image du CERN. 

La Conférence wallonne Einstein Telescope, organisée ce 18 mars par l’ULiège et l’Euregio Meuse-Rhin, était l’occasion d’informer tous les acteurs wallons sur les multiples facettes du projet et de faire un état des lieux du dossier.

Cette conférence s’est déclinée en 3 séances:

La séance scientifique s’est tenue dès 9h00 au Centre Spatial de Liège (CSL) en présence du Secrétaire d’Etat, Thomas Dermine, du Gouverneur de la Province de Liège, Hervé Jamar, le Président de l’Euregio-Meuse-Rhin, Luc Gillard, et son Directeur, Michael Dejozé, ainsi que de Belspo et de l’Antenne Interreg régionale Liège Euregio Meuse-Rhin.

La séance politique s’est tenue à l’Interface Entreprises-Université de Liège.

Les Ministres-Présidents Pierre-Yves Jeholet et Oliver Paasch, le Secrétaire d’État Thomas Dermine ainsi que les Ministres, Vice-présidents du Gouvernement wallon Willy Borsus et Philippe Henry, le Gouverneur de la Province de Liège, Hervé Jamar, le Président de l’Euregio-Meuse-Rhin, Luc Gillard, et son Directeur, Michael Dejozé, et les représentants des communes d’Aubel, Plombières et Dalhem concernées par le projet ont pris part à la Conférence Wallonne du Télescope Einstein. Les Cabinets des Ministres Di-Rupo, Glatigny et Morreale étaient représentés par leurs conseillers.

La séance économique s’est tenue l’après-midi en présence de PMEs et de grandes entreprises wallonnes, des pôles de compétitivité Skywin, MecaTech et GreenWin, des agences de développement de l’économie Sowalfin, SPI et wfg Ostbelgien, et du réseau LIEU.


(Eu)Regional SMEs benefit from Einstein Telescope: Implement your own ideas with up to 50,000 euro vouchers!

Euregio Meuse-Rhine, December 2021 – Our cross-border region is applying for the Einstein Telescope (ET), a third generation gravitational wave detector and cutting-edge research infrastructure of global importance. As of now, small and medium-sized enterprises (SMEs), start-ups and engineering companies with special expertise in the operational and geological technologies of the planned large-scale research facility can receive funding from 25,000 to 50,000 euros to realize their project idea. This involves application and experimental development projects that are innovative and carried out with a cross-border EMR company.

Call one for vouchers: Applications for innovation vouchers can be submitted until January 24th, 2022. For more information on the conditions of the competition, please visit:

Far more than 100 businesses, especially SMEs, joined the virtual information event on December 9th and informed them-selves about their inspiring opportunities.

The new offer is provided by the ET2MEs project involving 7 business development agencies/partners supported by INTERREG EMR VA Programme.

“We not only provide innovation vouchers worth 25,000 to 50,000 euros, but also directly connect the companies with complementary partners on the other side of the national borders,” explains Ralf P. Meyer, leadpartner of the ET2SMEs project at AGIT. “In all phases, from planning and construction to regular operation of the facility, companies from the EMR will be able to apply directly for tenders and thus for numerous contracts involving the Einstein Telescope,” emphasises Ralf P.Meyer.

Companies will also soon have the opportunity to present themselves and their know-how in a virtual 3D model of the ET. Furthermore, there is and will be the opportunity to participate to the joint ET Industrial Advisory Board ( ET IAB) of business and research for the large-scale facility as a dialogue partner and advisor in the coming years.

The aim of ET2SMEs is to bring the Einstein Telescope, for which the EMR is competing with excellent chances with Sardinia, closer to SMEs in the region and to let them participate directly in terms of technology development and economic exploitation. Technologies include optics, mirror coating, laser cryogenics, vacuum, precision mechanics / mechatronics, sensors / controls, but also drilling technology, modelling, simulation, artificial intelligence or hydrology.

The most important concern is to stimulate the cross-border innovation-oriented cooperation of technology-oriented companies and to produce targeted innovations that are significant not only for the ET, but also for other demanding applications and future markets.

The Einstein Telescope is a unique research project with global impact that will put Europe at the forefront of a new research discipline worldwide: The gravitational wave observatory of the latest, third generation will produce fundamentally new insights into the formation of the universe and the evolution of galaxies, stars and black holes. The investment for this large-scale research facility alone amounts to 1.9 billion euros, 500 direct and 1,150 indirect jobs will be created and another two billion euros are estimated for its operation until 2080.

Along with Sardinia (IT), the EMR is the last suitable region in Europe to apply for the location of this facility. A final decision on the location is expected in early 2025. Commissioning of the facility is planned from 2032.

First drilling in Banholt, the Netherlands

Since not much is known from the geological formations below the Cretaceous limestones below the area near Banholt we will drill a 250 m deep borehole. Like the other upcoming planned boreholes this borehole will be finished as a deep subsurface seismic noise station.
The KNMI – Royal Netherlands Meteorological Institute will install a surface and a deep seismometer in this borehole. For accurate noise measurements the borehole should be drilled perfectly straight and finished as a watertight, dry borehole.
To obtain information for our geophysical surveys like active, passive seismics and info for our 3D-geohydrological and geological modelling we will perform multiple tests and measurements inside this and other upcoming boreholes.
The outcoming samples will be tested in the lab to obtain info of the geotechnical conditions deep below this region.
The same applies for another 250 m deep drilling starting during October 2021 in #Cottessen within 100m distance of the Belgian-Dutch border.

Einstein Telescope approved
for ESFRI Roadmap 2021

On June 30th, the European Strategy Forum on Research Infrastructures (ESFRI) decided to include the Einstein Telescope in the 2021 upgrade of its roadmap. This confirms the relevance of this major international project for a next generation gravitational waves observatory for the future of research infrastructures in Europe and gravitational wave research at global level.

The Research Infrastructure Consortium Coordinators, Antonio Zoccoli of INFN and Stan Bentvelsen of Nikhef, are extremely excited about this result. “We are very pleased about this important result: the ESFRI approval acknowledges the value of our project and strengthens the Einstein Telescope at the European level”, says Zoccoli. “We will work synergistically for its development, confident that it is strategic to foster our knowledge of the universe, technological innovation and social growth.”

“The ESFRI-status is a major step towards the realisation of this European project, – says Bentvelsen – “scientifically the Einstein Telescope is undisputed, and with the ESFRI-status there is indispensable recognized support for its quality and impact. We are looking ahead to further develop the plans together with all countries involved.”

The Italian government submitted the proposal for the ESFRI-roadmap on September 9th, 2020 supported by the Netherlands, Belgium, Poland and Spain. “The preparation of the proposal has been a two years large effort involving several research institutions and universities, now composing the Einstein Telescope consortium, belonging to ten European countries and having real interdisciplinary competences”, says Michele Punturo, Coordinator of the ET-ESFRI proposal preparation.

Since September 9th, several of the people involved were invited to present the plans, to deepen specific aspects of the project and answer questions of the ESFRI evaluation committee. Among them was Marica Branchesi, member of the ET-ESFRI proposal preparation team: “We have worked hard to develop the science case of the Einstein Telescope. Each simulation showed us the enormous capabilities of the Einstein Telescope observing the Universe. The Einstein Telescope will revolutionize our knowledge in fundamental physics, astrophysics, and cosmology”, says Branchesi.

The Einstein Telescope was identified after a long and accurate process of evaluation and selection. During the ESFRI Assembly meeting, delegates officially decided to include the Einstein Telescope in the roadmap. This official European approval now brings the project into a new phase. The scientific Institutions involved from ten countries (Belgium, Germany, Hungary, Italy, Norway, Spain, Switzerland, Poland, The Netherland, United Kingdom) will now have to intensify their research and development work on the Einstein Telescope and gravitational waves. It will also speed up the ongoing subsurface studies for the characterization and evaluation of the candidate sites that could host the underground infrastructure.

A new window on the universe

The Einstein Telescope is a future underground observatory for gravitational waves. The instrument will be much more sensitive than existing gravitational wave detectors. Therefore, the observatory will enable scientists to peek into the ‘dark ages’ of the universe for the first time. Gravitational waves were detected for the first time in 2015 and offer a new way of studying the universe. Until their first detection, scientists could only study the universe by looking at light or radiation, but with gravitational waves they can observe vibrations of spacetime itself.

Although the existence of gravitational waves was already predicted by Albert Einstein a hundred years ago, he did not expect it was possible to ever detect them. Yet with the mind blowing technological developments of the last century, scientists and engineers have managed to reach the sensitivity and precision that is needed to observe them. This opened a new era in the study of the universe, the era of gravitational wave and multimessenger astronomy, and led to a Nobel prize in 2017. The Einstein Telescope will lead to many more unimaginable discoveries in the future in this new field of research.

The Einstein-Telescope – tracking down gravitational waves with high-tech

(WebTalk in german language)

Thursday, 29. October 2020, 04:30 pm

The Einstein telescope will be used in the border region between the Netherlands, Belgium and Germany to create a new type of underground telescope that will pick up gravitational waves from the universe and thus be able to track black holes, neutron stars or stellar explosions throughout the universe. It is based on 10 km long laser interferometers whose components are operated in an ultra-high vacuum at 10 Kelvin and at the same time are mounted in vibration-damped bearings. The triangular research infrastructure with a side length of 10 km at a depth of about 300 m in the Belgian-Dutch-German border region has to overcome many technological challenges in cooperation between industry and science in order to be realised.

Professor Dr. Achim Stahl, spokesman of the Physics Section and head of the III Physics Institute B of RWTH Aachen University, will use this WebTalk to provide an insight into the fascination of gravitational wave research and the resulting findings, as well as to address some of the technological challenges that need to be solved by means of future, cross-technology cooperation between regional players from industry and research. Within the Interreg EMR project E-TEST, the technological basis for the Einstein Telescope at demonstrator scale will be developed and solutions – ideally with regional partners – for the technological implementation of the Einstein Telescope will be worked on.

Are you also interested in the topic or do you develop components and systems in the fields of cryogenics, photonics, sensor technology, (quantum) optics, control, measurement and control engineering, materials and simulations? Learn more about the technological requirements and get access to the E-TEST consortium in this WebTalk.

Interreg is the European Union’s tool to support cross-border projects which otherwise would not be carried out.

The Interreg V-A Euregio Meuse-Rhine (EMR) programme invests almost EUR 100 million in the development of our region until the end of 2020.

The E-TEST project is carried out within the framework of the Interreg V-A Euregio Meuse-Rhine Programme, with € 7,5 million from the European Regional Development Fund (ERDF).

By investing EU funds in Interreg projects, the European Union is investing directly in economic development, innovation, territorial development, social inclusion and education in the Euregio Meuse-Rhine .
