A new type of low energy electron diffraction apparatus was constructed which is feasible for Auger electron energy analysis. The apparatus is composed of a fluorescent screen and four mesh electrodes of hemi-spherical form. By use of the apparatus, cleaning and adsorption of gases on the (110) face of tungsten crystal were investigated from observation of the LEED pattern as well as measurement of the Auger electron spectrum. Characteristics of energy resolution of the repelling electrodes was sufficiently sensitive to detect a small Auger peak at the initial stage of gas adsorption. Under the condition of controlled gas adsorption, it is confirmed approximately that there is a linear relation between the surface coverage of gas and the peak height of Auger electrons.
