Helium, due to its low boiling point (-269°C), is the only medium widely used to cool low-temperature superconductors. Superconductors are used to make superconducting magnets and resonance cavities, which are used in particle accelerators. Among many other things, accelerators are used for particle physics research.


CERN is the European Organisation for Nuclear Research, the largest particle physics center in the world.

The Large Hadron Collider is the largest and most powerful accelerator in the world. The LHC is located 100 meters underground in a tunnel with a circumference of 27 km. The design of the LHC is based on superconducting rails operating in a superfluid helium bath of 1.9 K (-271.3°C). High-Luminosity is CERN’s current flagship project, which is an upgrade of the LHC. The HL-LHC will replace the previous magnets with a new set of higher-performance ones. Cryogenic distribution and transfer systems were needed to test them and connect them to the current infrastructure. KrioSystem designed and manufactured Valve Boxes and multi-channel transfer lines for the transfer of liquefied helium (2021).

The European Spallation Source (ESS) is the European Research Infrastructure Consortium (ERIC), based on multidisciplinary research on the world’s most powerful neutron source. The aim of the project is to make a scientific breakthrough in research related to materials, energy, health, and the environment. KrioSystem delivered multi-channel transfer lines (350 m), valve boxes (31 pieces), Jumper type connections (31 pieces), and approximately 1,400 meters of auxiliary lines.


The FAIR center in Germany will enable research that will reveal previously undiscovered secrets about the structure of matter and the evolution of the universe. The heart of this facility will be an underground circular accelerator with a circumference of 1,100 meters – SIS100. It will allow accelerating protons and heavy ions. The Polish shareholder in FAIR is the Jagiellonian University which together with the Wrocław University of Science and Technology is coordinating among other things, the delivery and installation of cryogenic system elements as part of the Polish contribution. KrioSystem is responsible for the production and testing of 26 superconducting modules with a total length of 288 meters.


The European XFEL (European X-ray Free Electron Laser) was built at the DESY synchrotron research center in Hamburg. It generates 27,000 flashes per second, which makes the project unique on a global scale. KrioSystem’s contribution to the project included the delivery of a multi-channel cryogenic transfer line, a large helium cryostat, and the supply of auxiliary transfer lines. The infrastructure is primarily used to test resonance cavities at -271 degC.
