Jansen Cleanrooms & Labs and the Einstein Telescope
Most ambitious research infrastructure of the century
Across Europe, scientific institutions, governments and industry partners are preparing for one of the most ambitious research infrastructures of this century: the Einstein Telescope (ET). This next-generation underground gravitational-wave observatory will allow scientists to look deeper into the universe than ever before. Limburg is among the three regions that are currently in the running to host it. The final decision is expected in mid-2027, but the groundwork is well underway. And Jansen Cleanrooms & Labs is already playing an active role.
ETpathfinder: paving the way for the Einstein Telescope
Before the Einstein Telescope can be built, Europe needs a high-precision testing environment for its groundbreaking technologies. That is exactly what ETpathfinder provides: a state-of-the-art R&D infrastructure and cleanroom laboratory where researchers develop and validate the technologies needed for future gravitational-wave detection.
Jansen Cleanrooms & Labs designed and built crucial components of this facility, including advanced cleanrooms and lab infrastructure where ultra-sensitive optical and cryogenic experiments are conducted. More on the project:
For Jansen Cleanrooms & Labs, ETpathfinder represents more than a technical achievement: it is a demonstration of how future-proof construction, precision engineering and multidisciplinary collaboration come together in our work.
Why the Einstein Telescope matters for industry
The Einstein Telescope is not just a scientific milestone. It’s an engine for regional innovation, talent attraction and economic growth. As highlighted in a recent interview with our CEO Nadia Jansen the telescope is “a once-in-a-generation opportunity for Limburg” .
The project stimulates innovation in seven key technological domains identified for Flanders, including:
• Optics
• vibration isolation
• vacuum technology
• sensors & electronics
• future-proof construction
• digital technology & automation
• computational & data analysis
These domains are deeply connected to Jansen Cleanrooms & Labs’s core expertise, from high-precision building and technical installations to cleanroom engineering and smart building technologies.
A perfect match with Jansen Cleanrooms & Labs’s DNA
As a class-8 contractor with more than 750 in-house specialists, Group Jansen, which Jansen Cleanrooms & Labs is part of, thrives on projects where innovation, complexity and reliability are key. The Einstein Telescope fits seamlessly with that mindset. CEO Nadia Jansen explains: “The Einstein Telescope is a dream project that challenges our people to measure themselves against the absolute world top.”
She also highlights that the project aligns perfectly with Jansen Cleanrooms & Labs’s integrated approach: combining design, engineering, BIM, specialist construction and technical installations. From concept to commissioning.
If the Einstein Telescope is built in the Euregio Maas-Rijn, its impact will extend far beyond the scientific world. It will attract world-class researchers, engineers, technicians and entrepreneurs. According to Nadia Jansen: “Top scientists and companies from all over the world will come to Limburg. This can fundamentally transform our region.”
The arrival of such an ecosystem benefits not only the high-tech industry but also housing, education, hospitality and tourism.
Preparing today for tomorrow’s challenges
One of the key messages from both policymakers and industry leaders is clear: companies that prepare early will be ahead when the Einstein Telescope enters its procurement phase. “Companies often wait until tenders become concrete. But those who are smart build capacity and expertise now”, says Nadia Jansen. “That is why Jansen Cleanrooms & Labs is already strengthening partnerships with universities, research institutions and other technology-driven companies within the ET ecosystem.”
While the official bid for the Einstein Telescope will be submitted at the end of 2026, and the final decision is expected mid-2027, the preparation phase is in full motion. Regardless of the final location, the innovations developed for the project will have a global impact and Jansen Cleanrooms & Labs intends to be at the forefront. As the region’s construction and technology landscape evolves, we remain committed to shaping the future: by building the infrastructures where tomorrow’s discoveries will be made.
