Abstract

The operational principle and structural version of a gas discharge source of charged particle fluxes (both electrons and ions) is described. Some properties of particle fluxes generated by this source are given. The differences of this device from widely known electron and ion guns come down to the fact that it applies the effects of escaping electrons and gas rarefaction in a high-current electron discharge. The use of these effects ensures the performance of this device under a relatively high operating pressure (up to several kPa), provides large angular apertures of particle fluxes (up to 180°) for electrons for a large current amplitude (more than 100A), and allows obtaining a series of pulses with a duration longer than 10 ms each. The particle energy in the experiments described does exceed 750 eV. Several research problems for a more detailed study of physical processes occurring in the source are formulated and a few ways for its practical use are proposed.
