Concepts drawn from the kinetic theory of gases have been utilized to examine basic phenomena associated with cryopumping and low density flow. Relationships based on conductance have been used to examine the significance and interdependence of basic design parameters such as pressure, mass in-leakage rate, shielding, geometrical considerations, and flow regime. Considerations involved in predicting transition flow regime behavior are also discussed.
