New helium miracle in Chemnitz: research at the lowest temperature!

In a significant step into the future of research, a new helium liquefaction plant was put into operation at Chemnitz University of Technology on July 15, 2025. This modern system replaces a machine that is over 30 years old, which was now causing maintenance problems and could no longer be operated efficiently due to its age. The new technology will provide long-term support for research in the field of low-temperature physics, an important branch of physics that deals with matter at extremely low temperatures. Information about this can be found at Erzgebirge.tv.

Liquid helium, which boils at 4.15 Kelvin (minus 269 degrees Celsius), is essential for many scientific experiments. Extreme temperatures help to minimize disruptive influences. Applications range from scanning probe microscopy in physics to nuclear magnetic resonance spectroscopy in chemistry, but quantum computers also require very low temperatures, usually just a few millikelvin, in order to work efficiently. Loud Wikipedia The fundamentals of low-temperature physics and the associated technologies are crucial for the development of new materials and applications.

The new system and its functions

The newly installed system can produce up to 20 liters of liquid helium per hour and works in a closed circulation system. It consists of three main stages: compression, cooling and expansion. Liquid helium is specifically distributed in vacuum-insulated cans to the various research laboratories on campus. The operation of this system is supported by the Vorbuchner company, which has installed a modern turbo compressor.

Because helium is limited in time and expensive, prices have risen in recent years, leading to competition between hospitals, research facilities and the space industry. Helium is primarily produced as a byproduct of natural gas production, further limiting its availability. The availability of liquid gases is of central importance for future applications in cryogenics and low-temperature mechanics, which deal with the changes in materials under extreme conditions. Study Smarter highlights the important role of low-temperature mechanics, which studies the behavior of materials at extreme temperatures.

Gain education and experience

Another advantage of the new helium liquefaction system is the possibility of using it for teaching purposes. Physics students can deepen their knowledge and gain experience in internships and lectures on low-temperature experiments. Low-temperature physics is not only an exciting field of research, but also offers a wide range of career opportunities in the chemical industry and specific applications in space travel.

Overall, the new facility at Chemnitz University of Technology represents significant progress in the university and research, which opens up extensive possibilities in both academic and practical applications. Future physicists now have the chance to acquire the necessary know-how at the “coldest point” of Chemnitz to work successfully in the fascinating world of low-temperature physics and bottleneck sources for liquid gas.
