Abstract. The results of a detailed measurement of the dynamics of changes in the energy spectra of emitted electrons of non-activated and activated oxide thermocathodes with an increase in the emission voltage and cathode temperatures of ~590 °C and ~600 °C are presented; the changes in the spectra corresponded to the spotted cathode model. The results of measuring the energy spectrum of emitted electrons of a separate elementary emitting spot of an oxide thermocathode are presented, the spectrum had a Gaussian shape and was distinguished by a record narrow FWHM equal to 120 meV.

Key words: field emission, thermal emission, autocathode, oxide hot cathode, electron spectroscopy, electronic structure.
