Word Cryogenic is derived from greek word “kruos” & “genics” means very low temperature.
It is designed to reach ultra low temperature.
At a slow rate in order to prevent thermal shock to the components being treated.
MRI[Magnetic Resonance Image]
It is method of imaging objects.
It uses a strong magnetic field to detect the objects by radio-frequency pulse.
It uses liquid helium and super conducting magnets.
Liquid nitrogen used in cryogenic processors boils at 77 Kelvin.
COOLING MEDIUM
Most of cryogenic processors is used cooling medium as liquid nitrogen.
Liquid nitrogen adjust the changes in temperature.
Some cryogenic processors used Argon as cooling medium.
