“…-Nanosecond discharge in dense gases has attracted the attention of researchers due to the interesting physical phenomena involved and its practical applications [1][2][3]. Such a discharge is accompanied by the generation of runaway electrons (RAE) [3][4][5] with energies of tens of keV. These electrons are considered to play a major role in gas pre-ionization, seeding the gap with low-density plasma that allows the discharge to be developed in a nanosecond timescale.…”

“…In spite of copious experimental and simulation data [3][4][5][6][7][8][9][10][11] the origin of RAE emission and its role in the initiation of the discharge are not yet well defined. Namely, RAE are emitted or generated in the vicinity of a cathode [4] or the edge of a plasma streamer [5] propagating across the cathode-anode (CA) gap or from the virtual cathode, (a) E-mail: shurikyatom@gmail.com which can be formed near the cathode [10].…”

The results of experimental and numerical studies of the generation of runaway electrons (RAE) in a pressurized air-filled diode under the application of 20 ns, 5 ns and 1 ns duration high-voltage pulses with an amplitude up to 160 kV are presented. It is shown that with a 1 ns pulse, RAE with energy 20 keV reach the anode prior to the formation of the plasma channel between the cathode and anode. Conversely, with 20 ns or 5 ns pulses, RAE with energy 20 keV were obtained at the anode only after the formation of the plasma channel. In addition, the high-and low-impedance stages of the development of the discharge were found. Finally, a comparison between experimental and numerical simulation results is presented.

“…In recent years, the study of generation of runaway electron beams and X rays in atmospheric pressure air and other gases has been given considerable attention (see, for example, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and literature cited therein).…”

“…The generation and propagation of the back ground electron multiplication wave [5,7,23] can be used for excitation of the gaseous lamp [7,23,24] as well as laser [23][24][25][26] sources of radiation. The interest in the study of runaway electron beams and X rays from gas diodes filled with high pressure gases is also connected with the possibility of using an ultrashort runaway electron beam and diffuse discharge induced by the beam (see, for example, [27][28][29][30][31]).…”

Results of investigations of the generation of subnanosecond runaway electron beams and x radiation in gas diodes at elevated pressures are presented. The energy distributions of runaway electron beams generated in air at atmospheric pressure and the amplitude and duration of beam current pulses downstream of the foil have been measured, and also the mechanism of generation of a runaway electron beam has been analyzed. To record the beam current pulses, a collector which provided ~50-ps time resolution and a Tektronix TDS6604 real-time oscilloscope were used in the experiment. It has been shown that the new experimental data and model predictions confirm in the main the results earlier obtained at the Institute of High Current Electronics of the Russian Academy of Sciences Siberian Division. Evidence is cited that the key statements of L. P. Babich are erroneous.
