WebHow does a cryo pump work? A cryopump is vacuum pump that traps gases and vapors by condensing them on a cold surface. …The lightest gases such as hydrogen, helium, and neon are not condensed at 20K, therefore instead of relying on condensation alone, adsorbent made of special porous materials are provided to adsorb them. WebAerospace customer noticed that a cryopump installed on a large vacuum chamber would not pump down below 10 -5 range. Additionally he found oil contaminants on the 80K array. While there is oil used in the cryogenic system in the compressor and it can contaminate the helium circuit, this oil can not physically reach the vacuum vessel.
