| Summary: | A cryogenic pump is a cold surface employed to remove large volumes
of gases from a vacuum system by condensing and freezing the gas molecules.
Experimental results are presented for the cryopumping rate of
carbon dioxide gas on a surface cooled by liquid nitrogen, and for
nitrogen gas on a surface cooled by liquid helium. The nature of the
problems encountered in the design and construction of a cryogenic pumping
system are also discussed. |
