Why liquid helium ?
Cryogenics refers to the technology and science that deals with extremely low temperatures close to absolute zero (-273.15°C) in order to cool and manipulate materials and systems for special applications in areas such as superconductivity, space travel and medicine.
Liquid helium in particular, with a boiling point of -269°C, plays a central role here and is therefore indispensable for numerous scientific and industrial applications.
Superconductors show their remarkable properties, such as conductivity completely without resistance, only at extremely low temperatures. These materials enable lossless energy transfer and the generation of strong magnetic fields, making them indispensable for applications in energy technology, medical technology and high technology.
They are crucial for medical imaging (MRI), lossless power transmission, high-performance electronics, and have potential for future high-performance computing and innovative technologies. Their properties are revolutionizing various industries through improved efficiency, precision and the ability to explore new physical phenomena.

Particle accelerators
Particle accelerators use electromagnetic fields to accelerate charged particles to extremely high speeds and then cause them to collide in order to study subatomic processes. Cryogenics is essential to cool the superconducting magnets that hold and focus the particles on their path to extremely low temperatures and thus ensure their full performance.
Nuclear fusion
Nuclear fusion is the process by which light atomic nuclei, such as hydrogen isotopes, fuse at extremely high temperatures and pressures, releasing immense amounts of energy. Cryogenics is necessary to cool the superconducting magnets in fusion reactors that confine and control the hot plasma to enable a stable and efficient fusion reaction.
Superconductor
A superconductor is a material that reduces its electrical resistance to zero at low temperatures and can therefore conduct electrical currents without loss. They are used in magnetic resonance imaging (MRI) scanners, particle accelerators and efficient power lines to generate strong magnetic fields.
High-temperature superconductors are crucial for the power grid of the future, as they not only enable an extremely high current density, but are also able to transmit electricity without loss, which leads to a significant increase in efficiency and reliability of the entire energy system.
Space travel
Cryogenics is mainly used in space travel for the storage and utilization of cryogenic propellants such as liquid hydrogen and oxygen, which are necessary for efficient combustion. It also plays an important role in cooling scientific instruments and sensors to enable accurate measurements and in thermal management to protect critical components. In addition, cryogenics is used for the long-term storage of samples and as an energy source in future missions.
