Molecular Beam System for Gas-Surface Scattering Studies

Abstract
A molecular beam system for the study of gas scattering at surfaces is described. The system combines the use of a nozzle source for obtaining a relatively monoenergetic incident beam, with low temperature pumping which enables a clean system to be maintained. Further, the use of cryogenics enables the study of scattering behavior at low surface temperatures—a region which has to date not been investigated.
