Review of Molecular Beam Research in the M.I.T. Aeronautics and Astronautics Department 1970-1975.
Abstract
In the course of the research program into phenomena related to gas-surface interaction which the authors conducted over the last several years, the broad objective has been to seek answers to the following general question: Given a stream of gas molecules of known properties approaching a specified surface, how does one predict the velocity and flux distributions of the streams which leave the surface. Beginning with very simple configurations, they have attempted to account for an increasingly detailed extended set of properties of the solid surface, of the gas stream and of the interaction process. They have attempted to formulate the basic problem with a view to understanding molecular transport phenomena, first on inert metallic surfaces such as the skins of satellite vehicles in orbital flight, and later on ice crystals and nucleating centers in Brownian motion in the upper atmosphere. They have also begun to study the mechanism of interaction of molecular and atomic oxygen on graphite surfaces.
