Effects of cesiation on secondary-electron emission from MgO/Au cermets

Abstract
The effect of Cs adsorption on secondary-electron emission from MgO/Au cermets has been studied by both a rapid yield measurement technique and Auger electron spectroscopy. The presence of Cs enhances the emission from these materials, but the Cs is weakly bound and is easily removed by electron bombardment. The emission is not adversely affected by the possible alloying of Cs with Au.
