Pulsed Laser and Molecular Beam Apparatus for Surface Studies.

摘要

Equipment was purchased, using a grant awarded by the Air Force Office of Scientific Research under the DOD University Instrumentation Program, for the construction of an apparatus for the study of gas-surface interactions. This apparatus uses pulsed lasers both to keep the surface free of contamination and for probing surface phenomena, and pulsed molecular beam sources to dose the surface with the required gaseous samples. The experiments that will be carried out are in part described in the proposal A Pulsed Laser and Molecular Beam Apparatus for Surface Studies submitted by Howard University in November 1982 for review by AFOSR, under the DOD University Instrumentation Program. This report describes the progress made during the granting period in setting up the apparatus, and also the work that will be undertaken in the immediate future. The studies are currently supported by a grant from the Standard Oil Company of Ohio who have awarded us a $225,000 three-year contract for surface studies in collaboration with the Department of Electrical Engineering.
