Abstract:

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. Author
