N2 - A new field-emission cathode based on the W-Cs2Sb metal-semiconductor system is produced. The emission current of this cathode is one and one-half orders of magnitude higher than that of a tungsten cathode, and the FWHM of the energy spectrum is about 0.3 eV. An energy model of the given emitter is proposed. Using it, one can obtain theoretical values of the main cathode parameters which are in good agreement with the experimental ones.
