Cryopump - Wikipedia

A cryopump or a "cryogenic pump" is a vacuum pump that traps gases and vapours by condensing them on a cold surface, but are only effective on some gases. The effectiveness depends on the freezing and boiling points of the gas relative to the cryopump's temperature. They are sometimes used to block particular contaminants, for example in front of a diffusion pump to trap backstreaming oil, or ...

How cryopumps work: a detailed guide on their use

In cases where the condensate gets too thick, the cryopump reduces its performance and needs to be regenerated. This means switching the pump off, warming it up and releasing all gases previously pumped. These gases are either pumped out by an external pump, such as a rotary vane pump, dry screw pump or multistage roots pump.

How does a Cryopump work - Leybold

Cryocondensation is the physical and reversible bonding of gas molecules through Van der Waals forces on sufficiently cold surfaces of the same material. The bond energy is equal to the energy of vaporization of the solid gas bonded to the surface and thus decreases as the thickness of the condensate increases as does the vapor pressure.
