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

With a significant step into the future of research, a new helium fluid system was put into operation on July 15, 2025 at the Technical University of Chemnitz. This modern system replaces a 30 -year -old machine that has now led to maintenance problems and could no longer be operated efficiently due to its age. With the new technology, research in the field of low temperature physics, an important sub -area of physics, which deals with matter at extremely low temperatures, supports. Information on this can be found on 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 disturbing influences. Applications range from raster-probe microscopy in physics to magnetic resonance spectroscopy in chemistry, but quantum computers also require very low temperatures, usually only a few milliclevin to be able to work efficiently. According to wikipedia , the basics of deep temperature physics and the associated technologies are decisive 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 circulatory system. It consists of three main stages: compression, cooling and expansion. Liquid helium is specifically distributed to the various research laboratories on campus in vacuum-insulated jugs. The operation of this facility is supported by the company Vorbuchner, which has installed a modern turbo compressor.

Since Helium is limited and expensive, prices have increased in recent years and lead to a competition between clinics, research systems and the space industry. Helium is mainly obtained as a by -product of natural gas production, which further restricts its availability. The availability of liquid gases is of central importance for future applications in cryotechnology and low temperature mechanics, which deals with the changes in materials under extreme conditions. Study Smarter emphasizes the important role of deep temperature mechanics at extreme temperatures.

education and experience gather

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

Overall, the new system at the TU Chemnitz is a significant progress in the university and research, which opens up extensive options 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 successfully work in the fascinating world of deep temperature physics and the bottleneck sources for liquid gas.
