Helium cryogenics

Helium cryogenics refers to the use of helium as a refrigerant in various cryogenic applications, particularly at extremely low temperatures, typically below 4.2 Kelvin (-268.95 degrees Celsius or -452.11 degrees Fahrenheit). Helium is unique among the elements because it remains in a liquid state at these very low temperatures, which makes it an ideal choice for cooling superconductors, particle accelerators, and other scientific experiments that require ultra-low temperatures.
