THE ELECTRON AND IONIC EMISSION OF METAL-FILM CATHODES IN CESIUM VAPOR
Abstract
Some properties of electron and ion emission of porous ba-W and pressed Ba-Ni metal-film cathodes in cesium vapor are examined here. The experimental data obtained show: (1) the essential and typical adsorption effect caused by Cs vapor on the increased electron emission of those cathodes which already ave active Ba film on their surfaces; and (2) the presence in these cases of significant thermal ionization of the atoms of cesium vapors on the relatively depopulated microscopic regions of the surface of these cathodes, the ion current of which can serve as the characteristic of the degree surface inhomogeneity.
