Cryogenics

Abstract

    The cryogenics refers to the technology and art of producing the low temperature, which cannot be observed on or near the earth under natural condition. Basically cryogenics deals with the liquefaction of gases its application in various fields. Among the all gases Intelligent System is going to focus on HELIUM.
    Although helium is classified as an inert gas, and it is one of the most difficult gases to liquefy, its unusual properties have excited so much interest that helium has been the object of more experimental and theoretical research than any of   the other cryogenic fluid. Helium is a low density inert gas with a combination of unique properties that makes its availability essential for a wide range of industrial and scientific endeavors.
Until the World War II, the principle use of helium was for inflection of military higher-than- aircraft. Although such craft are no longer in operation, helium continues to be used as lifting gas because it is much safer than hydrogen.
Because of controlled rate of cooling the hardness of material increases without loss in ductility. Due to this technology the satellites (or mission) like IARS, COBE, ISO,XRS and rocket projection is easy by using liquid fuels like liquid HELIUM.
