Cryocooler
Encyclopedia
Cryocoolers are the devices used to reach cryogenic
temperatures by cycling certain gases.
A cryostat is likely to be used to reach and/or maintain similar conditions or keep some environment in cryogenic stasis. Through the use of cryocoolers, it is possible to reach temperatures near absolute zero.
Cryogenics
In physics, cryogenics is the study of the production of very low temperature and the behavior of materials at those temperatures. A person who studies elements under extremely cold temperature is called a cryogenicist. Rather than the relative temperature scales of Celsius and Fahrenheit,...
