Abstract: | The review of the methods for obtaining the runaway electron beams in the gas discharge is performed. The new method is offered,
using which the beam is first formed in a narrow gap (∼1 mm) between the cathode and the grid and then it is accelerated by
the field of the plasma column of the anomalous self-sustained discharge in the main gap (10–20 mm long). The electron beams
with an energy of about 10 keV and current density of 103 A/cm2 at a molecular nitrogen pressure of up to 100 Torr have been obtained experimentally. The results of research of the UV nitrogen
laser with an excitation via runaway electron beam and radiation of energy of ∼1 mJ are given. The UV nitrogen laser generation
with the energy of ∼1 mJ has been obtained by the runaway electron beams. |
