How Does A Cryogenic Vacuum Pump Work at Abby Daniel blog

How Does A Cryogenic Vacuum Pump Work. A cryopump is vacuum pump that traps gases and vapors by condensing them on a cold surface. They are available with giant pumping speeds. The liquid helium evaporates in the heat exchanger and thus cools down the cryopanel. The design of a cryopump has to combine cryogenic aspects and technological vacuum considerations in a unique manner, as the generation of low temperature itself presupposes. Liquid helium in sufficient quantity is pumped by an auxiliary pump from a reservoir into the evaporator in order to attain a sufficiently low temperature at the cold surface (cryopanel). It operates over a wide range of pressures, provides a clean vacuum. Cryopumps are much more powerful than oil diffusion pumps in large vacuum vessels. In this chapter, the authors review the mechanisms of cryocondensation and cryosorption on which all cryogenic pumping is.
