The dark matter experiment under Sedrun

Sedrun, in the heart of Graubünden, is ready to host a far-reaching quantum physics experiment. Sup professor Lucas Lombriser, who is responsible for the project, plans to conduct a dark matter experiment in the 800-meter well at the site. This experiment could revolutionize our understanding of dark matter, one of the universe's greatest mysteries.

Dark matter is a type of matter that does not emit or absorb electromagnetic radiation, making it invisible to our observing instruments. Despite its enigmatic nature, dark matter has been detected through its gravitational consequences. Sedrun's experiment aims to directly capture dark matter through its interaction with normal matter.

The experiment will be conducted in the Sedrun well, which offers natural protection from external noise sources. The well was chosen for its stability and its proximity to a source of hydroelectric power, which will provide the electricity needed for the experiment.

Professor Lombriser said: "Sedrun is the ideal place for this experiment. Its geographical location and its infrastructure

Operational details

Professor Lucas Lombriser explains that these experiments are advancing quantum technology and will be useful for future quantum computers. In addition, with atomic interferometry, extremely precise accelerometers can be built that could be used to navigate autonomously without relying on GPS satellites subject to error and interference.

The dark matter experiment, conducted by Professor Lucas Lombriser's research group at the University of Lausanne, is a significant example of the collaboration between science and technology in Switzerland. This project, funded by the Swiss National Fund for Scientific Research (SNF), received funding of 1.5 million Swiss francs over a period of 5 years.

The main objective of this experiment is to study dark matter, a form of matter that does not emit or absorb light and that makes up about 27% of the mass of the universe. Dark matter is responsible for the formation of galactic structures and the evolution of the universe, but its nature is still unknown.

The experiment under Sedrun uses a technique called “atomic interferometry” to measure dark matter fluctuations. This technique is based on the ability of atoms to interfere with themselves, creating an interference pattern that can be used to measure the properties of dark matter.

Key points

The quantum physics experiment could soon be conducted in the 800-meter well at Sedrun. The project manager is sup Professor Lucas Lombriser. This ambitious project aims to study dark matter, one of the greatest unknowns of modern cosmology.

Dark matter is an unknown form of matter that is believed to make up about 27% of the mass-energy of the universe. It does not emit or absorb electromagnetic radiation, so it is invisible and cannot be observed directly. However, its presence can be deduced from its gravitational interactions with normal matter.

Sedrun's experiment will take place in the 800-meter well, which will be used as a kind of artificial “micro-gravity.” The well will be used to create a weak gravitational field, which will allow dark matter to be studied under controlled conditions. Professor Lombriser said that “the Sedrun well will be a natural laboratory for studying dark matter under micro-gravity conditions.”

The project is funded by the Swiss Foundation for Science (SNF) with an amount of CHF 1.2 million. The Foundation said that "the Sedrun project is an excellent example of how science can be supported in Switzerland." The project is also supported by the canton of Graubünden, which provided a contribution of 500,000 Swiss francs.
