A noise model in which fluctuation noise of output current is determined by weakly emitting fragments of thermionic cathode working in the saturation regime (defects on the emitting surface) is proposed. The measured noise characteristics of the shot

The results of experimental measurements of dispenser cathodes shot and flicker noise show that there is a relation between the experimental diodes noise characteristics and the uniformity of emitting surface. Based on these results a computer model
