THE TRAPPING EFFECT IN CRYOPUMPING
Abstract
A theoretical analysis of the trapping phenomenon is presented, based on the assumptions of adsorption and solution of the trapped gas. Supporting experimental data are given at total pressures ranging from 1/100,000 to 1/100 mm Hg for the trapping of air by water condensate on a spherical cryosurface at liquid nitrogen temperature.
