The cryogenic pump without liquid nitrogen trapping showed pumpdown performance comparable to the turbomolecular pump with liquid nitrogen trapping. The cryopump provides fast, clean pumping of all gases in the 10 −3 to 10 −9 Torr range. The cryopump operates on the principle that gases can be condensed and held at extremely low vapor pressures, achieving high speeds and throughputs. Meer weergeven 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 … Meer weergeven Cryopumps are commonly cooled by compressed helium, though they may also use dry ice, liquid nitrogen, or stand-alone versions … Meer weergeven Early experiments into cryotrapping of gasses in activated charcoal were conducted as far back as 1874. The first cryopumps mainly used liquid helium to cool the pump, either in a large liquid helium reservoir, or by continuous flow into the … Meer weergeven longmont office space
