    CRYOGENICS—–Liquefaction of Helium and Magnetic Cooling —–SHEET 5

    CRYOGENICS—–Liquefaction of Helium, Magnetic Cooling and Nuclear demagnetization—–SHEET 5 Liquefaction of Helium by Collins’s Cryostat Principle (i)  Polytropic expansion for precooling Throttling for liquefaction. Liquifaction of helium(Fig.4) uses normal boiling liquid nitrogen for precooling before the helium enters the first cascade heat exchanger. Since helium liquefies at a lower temperature than that of even hydrogen, […]

    ** Cryogenics and Liquefaction of Gases

    Cryogenics and Liquefaction of Gases Cryogenics  involves the study of temperatures below -1500C, how to produce them, and which materials behave at those temperatures. There are many areas of interest where we need cryogenic temperatures such as (i)   Storage of large volumes of gases in small space in the liquefied form (ii)  Preservation of […]
