Abstract

The experimental and theoretical studies of the emission characteristics of a multiple-tip cathode matrix made of glassy carbon are discussed. The thermal conditions of microtips are calculated based on the experimental current-voltage characteristics of a cathode matrix and the effective emission cross sections. The dependences between the emitting-center temperature and the autoemission current are found, and the maximum temperatures corresponding to the boundary of the stable autoelectronic emission zone are determined. The distribution functions characterizing the total energy of autoelectrons are calculated allowing for the emitting-center temperatures. The dependences of the Fermi level shift and the autoelectron energy spectrum width on the temperature are revealed.
