We have studied the conditions for the formation of a pulsed beam of runaway electrons in a diode filled with air at atmospheric pressure, whereby the current and voltage pulses in the system were measured with a subnanosecond time resolution. It is experimentally demonstrated for the first time that the electron beam appears on the leading front of the voltage pulse at a relatively small voltage on the discharge gap. At atmospheric pressure, a full width at half maximum of the current pulse does not exceed 0.3 ns.read more

TL;DR: In this paper, a supershort avalanche electron beam (SAEB) was generated from the inter-electrode gap at a solid angle exceeding 2π sr. In air, at a pressure of 1 ǫ atm with a sharply non-uniform electric field, an SAEB was generated by gas-filled diodes.

Supershort electron beam from air filled diode at atmospheric pressure
TL;DR: In this article, the properties of an electron beam (e-beam) formed in air under atmospheric pressure are reported, where the authors used the nanosecond generators RADAN-303 (two devices) and RadAN-220, producing up to 400 kV and subnanosecond rise time.

High-power subnanosecond beams of runaway electrons and volume discharge formation in gases at atmospheric pressure
TL;DR: In this paper, a non-local criterion for runaway electrons generation is proposed, which is a universal two-valued dependence of the critical voltage U cr on pd for a certain gas (where p is the pressure and d is the interelectrode distance).

TL;DR: In this article, a non-local criterion for runaway electron generation is proposed, which results in the universal two-valued dependence of critical voltage Ucr on pd for a certain gas (p is pressure, d is interelectrode distance).

Electron beams formed in a diode filled with air or nitrogen at atmospheric pressure
TL;DR: In this paper, the electron beam formation in a diode filled with a molecular gas at atmospheric pressure was studied and it was suggested that the main fraction of runaway electrons at low initial values of the parameter E/p (∼0.1 kV/(cm Torr)) is formed in the space between cathode plasma and anode.
