12.Even though the cathode surface exhibits gross deformations caused by build‐up, it appears to remain atomically smooth for the values of applied field and temperature of interest in the operation of heated tungsten field cathodes. At still higher fields (), Drechsler has shown that the atomically smooth surface becomes unstable and changes to a hill and valley structure.

14.This value of might at first appear unreasonably large; however, it is smaller (by a factor of at least ) than the average number of impurity atoms per in the Phillips type HCA tungsten wire commonly used in the fabrication of field cathodes.

20.Characteristic effects occasionally observed on emission patterns, and reported by Dyke and Barbour (see footnote reference 2) appear to provide experimental evidence of the eruption of internal impurities onto the surface of heated tungsten field cathodes.
