Much work is being done in Europe to develop enabling technologies and strengthen a network of research laboratories for the Einstein Telescope (ET), the future gravitational-wave observatory scheduled to start construction in 2028 with full operational capacity by 2035.
The telescope will be built underground, with tunnels approximately 10 kilometers long at a depth of 250metres, housing the laser and mirror systems needed to detect gravitational waves from cosmic events like black hole and neutron star collisions.
MITI funding released
Most recently, the Italian MITI (Multimessenger Infrastructures and Technologies project) was launched by the Italian Ministry of University and Research (MUR) under the National Programme for Research, Innovation and Competitiveness (PN RIC) 2021-2027. The project comes with €15 million in funding to be allocated to sections related to ET planning – including the National Institute for Nuclear Physics (INFN): Perugia (a coordinating institution) and the INFN Southern National Laboratories.
The funding builds on the legacy of the previous ETIC (Einstein Telescope Infrastructure Consortium) project, funded through Italy’s National Recovery and Resilience Plan (NRRP) and completed on 30 June this year.
ETIC focused on carrying out a feasibility study and site characterisation for the Italian candidate site to host the Einstein Telescope – located near the former Sos Enattos mine in the province of Nuoro, in Sardinia – and on establishing and strengthening a national network of research and development laboratories dedicated to the future interferometer.
With a planned duration of 30 months, MITI will ensure continuity with ETIC, particularly by consolidating the research activities of the new laboratories established across Italy over the past two years within the framework of the NRRP project.
In addition to further enhancing these research infrastructures – which are dedicated to developing innovative technologies essential for ET – MITI will place a strong emphasis on technology transfer, actively involving industry in collaborative co-design processes and prototype development.
“Major research infrastructures begin to take shape long before construction starts”, said Anna Maria Bernini, Italy’s Minister of University and Research. “This is the purpose of the Ministry’s investment in the MITI project: to strengthen Italy’s research ecosystem and create the conditions for our country to play a leading role in major scientific challenges such as the Einstein Telescope”.
The Einstein Telescope will result in regional innovation, talent attraction and economic growth projected to stimulate innovation in key technological domains such as:
• optics
• vibration isolation
• vacuum technology
• sensors and electronics
• future-proof construction
• digital technology and automation
• computational & data analysis
Other organisations such as Jansen Cleanrooms & Labs have also developed facilities in advance of the decisions being made regarding location of the ET.
The company designed and built components of a facility to house the project, located in Maastricht University in Maastricht, Netherlands. The build includes advanced cleanrooms and lab infrastructure where ultra-sensitive optical and cryogenic experiments are conducted.
The project was commissioned by the University of Maastricht who enlisted the company to construct a scale model of the Einstein Telescope. Jansen Cleanroom & Lab specialists therefore designed and built a cutting-edge cleanroom spanning 900 m², certified to ISO-class 8 standards.
This facility includes advanced technical features, including a vibration-free, anti-static floor, smooth acoustic walls, and a robust air filtration system capable of cycling the air 20 times per hour—an impressive capacity of up to 100,000 m²/hour.
In addition, the cleanroom is equipped with essential elements such as air showers, LAF cabinets, and a comprehensive network of hot and cold piping. To streamline the process and ensure precision, the entire project was modeled using Building Information Modeling (BIM), facilitating efficient preventive maintenance. This development represents a significant milestone for science, providing the tools to simulate gravitational waves and explore the origins and dynamics of the Earth, stars, and planets.
The company executed the entire process, from initial design to final validation, in just eight months and it was completed in 2021.
This next-generation underground gravitational-wave observatory will allow scientists to look deeper into the universe than ever before and organisations such as Jansen Cleanrooms are already preparing to support the project via the ET pathfinder.
The project, called the ETpathfinder, is a state of the art R&D infrastructure and cleanroom laboratory that will enable researchers to develop and validate the technologies needed for future gravitational-wave detection.
The Einstein Telescope is planned to be operational by 2035 and is designed to run for at least 50 years. It aims to detect gravitational waves with up to 100 times higher sensitivity than current observatories, providing unprecedented insights into the formation of the Universe, black holes, and other astrophysical ph
