Abstract: Electron source made notably in the form of a micropoint cathode electrode in which a microcathode is located in a cavity (CA) of a dielectric (3). A first gate electrode (VG1) surrounds the cavity (CA) and a second gate electrode (VG2) surrounds the first gate electrode (VG1). The different electrodes are carried to potentials such that the first gate electrode (VG1) acts as an extraction electrode and the second gate electrode acts as a focusing electrode.
