Abstract
Estimates of the energy necessary to provide for the emission of a single photoelectron from a cathode in open discharge show that (i) the discharge cannot be maintained at the expense of photoemission and (ii) the contribution of photoelectrons to the energy efficiency of the electron beam formation is negligibly small.
