Abstract
The beam brightness B of smooth thermionic cathodes is examined in the temperature-limited regime as affected by work-function patchiness. Beam brightness is expressed in terms of the autocorrelation function of the work function nonuniformity in the laminar approximation. The dependence on extraction field strength and other factors is discussed.
