Abstract

The total electron emission of better than 99.9% bulk purity aluminum, titanium, iron, and copper has been measured for six photon energies impinging at near normal incidence (90 ± 0.8°) to the electron emitting surface. Six nearly monochromatic photon energies between 0.109 and 1.49 keV were used. Surface smoothness, oxygen, and carbon contaminants were found to strongly influence the electron emission from these devices.
