The Use of Some Metal Photocathodes for Absolute Intensity Measurements in the Soft X-ray-Vacuum Ultraviolet

Volume 31, Number 4 (Aug. 1977) Page 317-320

Burns, Erskine J.T.; Thurston, John F.


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.
