Runaway electrons beams in the gas disharge for UV nitrogen laser exitation
The review of methods of reception of runaway electrons beams in the gas discharge is spent. The new method of runaway electrons beams generation at gaseous discharge is offered, in this method at first the beam is forming in a narrow gap (~ 1 mm) between the cathode and grid, and then it is accelerated by the field of plasma column of the abnormal self-sustained discharge in the main gap (with length of 10-20 mm). This method experimentally provides electron beams with energy nearby 10 keV and current density larger than 103 A/cm2 at molecular nitrogen pressure of nearby 100 Torr. The results of research of UV nitrogen laser with an excitation via runaway electrons beam and radiation energy of ~ 1 mJ are given.
